Wind power generating system  

SciTech Connect

Normally feathered propeller blades of a wind power generating system unfeather in response to the actuation of a power cylinder that responds to actuating signals. Once operational, the propellers generate power over a large range of wind velocities. A maximum power generation design point signals a feather response of the propellers so that once the design point is reached no increase in power results, but the system still generates power. At wind speeds below this maximum point, propeller speed and power output optimize to preset values. The propellers drive a positive displacement pump that in turn drives a positive displacement motor of the swash plate type. The displacement of the motor varies depending on the load on the system, with increasing displacement resulting in increasing propeller speeds, and the converse. In the event of dangerous but not clandestine problems developing in the system, a control circuit dumps hydraulic pressure from the unfeathering cylinder resulting in a predetermined, lower operating pressure produced by the pump. In the event that a problem of potentially cladestine consequence arises, the propeller unfeathering cylinder immediately unloads. Upon startup, a bypass around the motor is blocked, applying a pressure across the motor. The motor drives the generator until the generator reaches a predetermined speed whereupon the generator is placed in circuit with a utility grid and permitted to motor up to synchronous speed.

Flapping wing applied to wind generators  

Science Journals Connector (OSTI)

The new conditions at the international level for energy source distributions and the continuous increasing of energy consumption must lead to a new alternative resource with the condition of keeping the environment clean. This paper offers a new approach for a wind generator and is based on the theoretical aerodynamic model. This new model of wind generator helped me to test what influences would be if there will be a bird airfoil instead of a normal wind generator airfoil. The aim is to calculate the efficiency for the new model of wind generator. A representative direction for using the renewable energy is referred to the transformation of wind energy into electrical energy with the help of wind turbines; the development of such systems lead to new solutions based on high efficiency reduced costs and suitable to the implementation conditions.

A novel dual stator-winding induction generator system applied in wind power generation  

Science Journals Connector (OSTI)

This paper presents a novel usage of 6/3-phase dual stator-winding induction generator (DWIG) with a static excitation power controller (SEC) as a wind power generator. This generator is composed of a standard squirrel-cage rotor and two sets of winding housed in the stator slots. One is referred to as the 6-phase power winding, and the other is defined as the 3-phase control winding. On the basis of the instantaneous power theory, the control mechanism of DWIG wind power system is analysed, and the control winding flux orientation control strategy is obtained consequently. The simulation and experimental results from a prototype of 18 kW 6/3-phase DWIG wind power system are presented to verify the correctness and feasibility of control strategy, and a desirable performance is implemented.

Potential wind power generation in South Egypt  

Science Journals Connector (OSTI)

Egypt is one of the developing countries. The production of electricity in Egypt is basically on petroleum, natural gas, hydro-power and wind energy. The objective of this work to prove the availability of sufficient wind potential in the wide area of deep south Egypt for the operation of wind turbines there. Nevertheless, it gives in general an approximate profile which is useful to the wind parks design for this area. The data used in the calculation are published and analyzed for the first time. The diagrams of the measured wind data for three meteorological stations over a period of two years (wind speed, frequency, direction), wind shear coefficient, the mean monthly and annual wind speed profile for every location are presented. Monthly Weibull parameters, standard deviation and coefficient of variation have been statistically discussed. A comparison of the rose diagrams shows that the wind speed is more persistent and blow over this region of Egypt in two main sectors N and NNW with long duration of frequencies from 67% to 87% over the year with an average wind speed in the range 6.87.9m/s at the three stations. Evaluation of monthly wind energy density at 10m height by two different methods was carried out. And the final diagram for every site shows no significant difference between them. The annual natural wind energies at 70m A.G.L. lie between 333 and 377W/m2 for Dakhla South and Kharga stations, respectively, which is similar to the inland wind potential of Vindeby (Denmark) and some European countries. These results indicate that Kharga and Dakhla South locations are new explored sites for future wind power generation projects.

Operation of a third generation wind turbine  

SciTech Connect

A modern wind turbine was installed on May 26, 1982, at the USDA Conservation and Production Research Laboratory, Bushland, Texas. This wind machine was used to provide electrical energy for irrigation pumping and other agricultural loads. The wind turbine purchased for this research is an Enertech Model 44, manufactured by Enertech Corporation, Norwich, Vermont. The horizontal-axis wind turbine has a 13.4 m diameter, three-bladed, fixed-pitch rotor on a 24.4-m tower. The blades are laminated epoxy-wood, and are attached to a steel hub. A 25-kW induction generator provides 240 V, 60 Hz, single-phase electrical power. The wind turbine operated 64 percent of the time, while being available to operate over 94 percent of the time. The unit had a net energy production of over 80,000 kWh in an average windspeed of 5.9 m/s at a height of 10 m in a 16-month period. The blade pitch was originally offset two degrees from design to maintain power production within the limitations of the gearbox, generator, and brakes. A maximum output of 23.2 kW averaged over a 15-second period indicated that with a new brake, the system was capable of handling more power. After a new brake was installed, the blade pitch was changed to one degree from design. The maximum power output measured after the pitch change was 29.3 kW. Modified blade tip brakes were installed on the wind turbine on July 7, 1983. These tip brakes increased power production at lower windspeeds while reducing power at higher windspeeds.

ARE660 Wind Generator: Low Wind Speed Technology for Small Turbine Development  

SciTech Connect

This project is for the design of a wind turbine that can generate most or all of the net energy required for homes and small businesses in moderately windy areas. The purpose is to expand the current market for residential wind generators by providing cost effective power in a lower wind regime than current technology has made available, as well as reduce noise and improve reliability and safety. Robert W. Preus experience designing and/or maintaining residential wind generators of many configurations helped identify the need for an improved experience of safety for the consumer. Current small wind products have unreliable or no method of stopping the wind generator in fault or high wind conditions. Consumers and their neighbors do not want to hear their wind generators. In addition, with current technology, only sites with unusually high wind speeds provide payback times that are acceptable for the on-grid user. Abundant Renewable Energys (ARE) basic original concept for the ARE660 was a combination of a stall controlled variable speed small wind generator and automatic fail safe furling for shutdown. The stall control for a small wind generator is not novel, but has not been developed for a variable speed application with a permanent magnet alternator (PMA). The fail safe furling approach for shutdown has not been used to our knowledge.

Generation of large-scale winds in horizontally anisotropic convection  

E-Print Network (OSTI)

We simulate three-dimensional, horizontally periodic Rayleigh-B\\'enard convection between free-slip horizontal plates, rotating about a horizontal axis. When both the temperature difference between the plates and the rotation rate are sufficiently large, a strong horizontal wind is generated that is perpendicular to both the rotation vector and the gravity vector. The wind is turbulent, large-scale, and vertically sheared. Horizontal anisotropy, engendered here by rotation, appears necessary for such wind generation. Most of the kinetic energy of the flow resides in the wind, and the vertical turbulent heat flux is much lower on average than when there is no wind.

Wind Generation on Winnebago Tribal Lands  

SciTech Connect

The Winnebago Wind Energy Study evaluated facility-scale, community-scale and commercial-scale wind development on Winnebago Tribal lands in northeastern Nebraska. The Winnebago Tribe of Nebraska has been pursuing wind development in various forms for nearly ten years. Wind monitoring utilizing loaned met towers from NREL took place during two different periods. From April 2001 to April 2002, a 20-meter met tower monitored wind data at the WinnaVegas Casino on the far eastern edge of the Winnebago reservation in Iowa. In late 2006, a 50-meter tower was installed, and subsequently monitored wind data at the WinnaVegas site from late 2006 through late 2008. Significant challenges with the NREL wind monitoring equipment limited the availability of valid data, but based on the available data, average wind speeds between 13.6 14.3 miles were indicated, reflecting a 2+/3- wind class. Based on the anticipated cost of energy produced by a WinnaVegas wind turbine, and the utility policies and rates in place at this time, a WinnaVegas wind project did not appear to make economic sense. However, if substantial grant funding were available for energy equipment at the casino site, and if either Woodbury REC backup rates were lower, or NIPCO was willing to pay more for wind power, a WinnaVegas wind project could be feasible. With funding remaining in the DOE-funded project budget,a number of other possible wind project locations on the Winnebago reservation were considered. in early 2009, a NPPD-owned met tower was installed at a site identified in the study pursuant to a verbal agreement with NPPD which provided for power from any ultimately developed project on the Western Winnebago site to be sold to NPPD. Results from the first seven months of wind monitoring at the Western Winnebago site were as expected at just over 7 meters per second at 50-meter tower height, reflecting Class 4 wind speeds, adequate for commercial development. If wind data collected in the remaining months of the twelve-month collection period is consistent with that collected in the first seven months, the Western Winnebago site may present an interesting opportunity for Winnebago. Given the distance to nearby substations, and high cost of interconnection at higher voltage transmission lines, Winnebago would likely need to be part of a larger project in order to reduce power costs to more attractive levels. Another alternative would be to pursue grant funding for a portion of development or equipment costs, which would also help reduce the cost of power produced. The NREL tower from the WinnaVegas site was taken down in late 2008, re-instrumented and installation attempted on the Thunderway site south of the Winnebago community. Based on projected wind speeds, current equipment costs, and the projects proximity to substations for possible interconnection, a Thunderway community-scale wind project could also be feasible.

Design of a wind turbine-generator system considering the conformability to wind velocity fluctuations  

SciTech Connect

The conformability of the rated power output of the wind turbine-generator system and of the wind turbine type to wind velocity fluctuations are investigated with a simulation model. The authors examine three types of wind turbines: the Darrieus-Savonius hybrid, the Darrieus proper and the Propeller. These systems are mainly operated at a constant tip speed ratio, which refers to a maximum power coefficient points. As a computed result of the net extracting power, the Darrieus turbine proper has little conformability to wind velocity fluctuations because of its output characteristics. As for the other turbines, large-scale systems do not always have an advantage over small-scale systems as the effect of its dynamic characteristics. Furthermore, it is confirmed that the net extracting power of the Propeller turbine, under wind direction fluctuation, is much reduced when compared with the hybrid wind turbine. Thus, the authors conclude that the appropriate rated power output of the system exists with relation to the wind turbine type for each wind condition.

Greenhouse gas emissions from electricity generated by offshore wind farms  

Science Journals Connector (OSTI)

Abstract For wind power generation offshore sites offer significantly better wind conditions compared to onshore. At the same time, the demand for raw materials and therefore the related environmental impacts increase due to technically more demanding wind energy converters and additional components (e.g. substructure) for the balance of plant. Additionally, due to environmental concerns offshore wind farms will be sited farshore (i.e. in deep water) in the future having a significant impact on the operation and maintenance efforts (O&M). Against this background the goal of this analysis is an assessment of the specific GHG (greenhouse gas) emissions as a function of the site conditions, the wind mill technology and the O&M necessities. Therefore, a representative offshore wind farm is defined and subjected to a detailed LCA (life cycle assessment). Based on parameter variations and modifications within the technical and logistical system, promising configurations regarding GHG emissions are determined for different site conditions. Results show, that all parameters related to the energy yield have a distinctive impact on the specific GHG emissions, whereas the distance to shore and the water depth affect the results marginally. By utilizing the given improvement potentials GHG emissions of electricity from offshore wind farms are comparable to those achieved onshore.

Petschek-type time-dependent reconnection (TDR) and quasi-stationary reconnection (QSR) models are considered to understand reconnection outflow structures and the features of the associated locally generated turbulence in the solar wind. We show that the outflow structures, such as discontinuites, Kelvin-Helmholtz (KH) unstable flux tubes or continuous space filling flows cannot be distinguished from one-point WIND measurements. In both models the reconnection outflows can generate more or less spatially extended turbulent boundary layers (TBDs). The structure of an unique extended reconnection outflow is investigated in detail. The analysis of spectral scalings and break locations show that reconnection outflows can control the local field and plasma conditions which may play in favor of one or another turbulent dissipation mechanisms with their characteristic scales and wavenumbers.

More wind generation means lower GHG emissions, right?  

SciTech Connect

The answer to what will be the net effect of an x percent increase in wind generation on GHG emissions in a given system is not a simple y percent -- but is likely to depend on many variables, assumptions, modeling, and number crunching. But the result is important, and hence there has been a flurry of contradictory studies, confusing policymakers and the general public alike. While one can certainly find exceptions, under most circumstances, more renewable generation can be expected to result in lower GHG emissions.

An overview on doubly fed induction generators? controls and contributions to wind based electricity generation  

Science Journals Connector (OSTI)

Abstract Undoubtedly, energy has a significant role in economic growth and technical developments. Renewable energy resources are becoming more important in recent years due to their tremendous contributions to the independence of power generation industry from traditional fossil energy resources. Wind energy has been outstanding among renewable energy resources since continuous harvestable potential on the earth is approximately around 106MW. Concerning the variable nature of wind energy, the variable speed machines, especially doubly fed induction generators (DFIG) are one of the considerations for wind energy conversion systems (WECS). Their implementation in renewable energy conversion systems is dramatically increasing due to their numerous advantages such as low cost and small size, the elimination of external DC source, the ability to produce maximum power under various wind and rotational speeds, the capability of controlling active and reactive power, and the opportunity to employ cheaper and smaller convertors and controllers. This paper is an extensive review of researches in the past 30 years on DFIG. The study starts with describing general perspective on wind energy and commonly used generators in wind conversion. Then it presents more details on \\{DFIGs\\} operational modes, utilizations, their modeling and simulation. It is followed by DFIG control methods and overviews of different employed electrical and mechanical controlling methods. Finally the review on the mutual impact of DFIG on power networks and vice versa, including wind uncertainty, power and frequency stability, power and voltage quality, operation under steady state, dynamic and fault conditions, and protections is given. Based on the review DFIG has advantages in terms of electrical, mechanical, and economic perspectives. It can be concluded that the DFIG has the most promising future for \\{WECSs\\} in power generation to complement the conventional systems.

The economics of wind energy within the generation mix  

Science Journals Connector (OSTI)

With more than 15,000 plants of different capacity ranges, Germany has become the world's No. 1 in generating electricity from wind power, covering around 4% of the electricity requirements at home. This is due on the one hand to the successful promotion by the Renewable Energy Act (EEG) and, on the other hand, to the tax breaks from loss allocation and depreciation. During low-load periods, load dispatchers today already have to balance power gradients of more than 10% of the respective network load per minute, which are increasingly covered by the provision of balancing power from conventional power plants. The legally fixed permanent subsidy burden of the electricity industry due to the high compensation fee for wind power alone currently amounts to euro 1.4 billion a year. If base load capacity from nuclear power plants is replaced in the medium term, this will not reduce but rather increase CO2 emissions as generation from gas turbines will have to be increased temporarily in times of flagging winds.

Controller for a small induction-generator based wind-turbine  

Science Journals Connector (OSTI)

Design of a low-cost micro-controller for a small induction-generator based grid-connected wind-turbine is presented in this paper. The controller senses the parameters of the wind-turbine generator and the grid, and makes decisions about grid connection and disconnection. Low-cost instrumentation circuitry has been developed to measure the generator and grid parameters. Based on the measurement of voltage and frequency of the wind-turbine generator and the grid side, a control decision is taken to connect the system to the grid. The controller makes decision to disconnect the system from the grid based on the power flow measurement between the wind turbine and the grid. The power flow between wind turbine and the grid depends upon the availability of the wind. The prototype controller has been developed based on a micro-controller PIC16F877 and has been tested in the laboratory.

Control of wind generator associated to a flywheel energy storage system  

Science Journals Connector (OSTI)

In this paper, a doubly fed variable speed wind induction generator connected to the grid associated to a flywheel energy storage system (FESS) is investigated. The dynamic behaviour of a wind generator, including the models of the wind turbine (aerodynamic), the doubly fed induction generator (DFIG), a ac/ac direct converter, the converter control (algorithm of VENTURINI) and the power control of this system, is studied. Also investigated is a control method of the FESS system, which consists of the classical squirrel-cage induction machine supplied off the variable speed wind generator (VSWG) through a rectifierinverter cascade arrangement. Simulation results obtained on the basis of the dynamic models of the wind generator are presented, for different operating points, to demonstrate the performance of the proposed system.

Study on environmental impact model of grid-connected wind power generation  

Science Journals Connector (OSTI)

As a clean and renewable energy source, wind power is independent from the traditional external energy change, which makes it one of the most promising ways of clean energy generation. It is well known that wind power has obvious energy saving efficiency. But for long-term consideration, wind power generation still has certain impacts on human life. Therefore, standing in the point of the negative effects of wind energy, this paper makes a further research on environmental issues of wind energy development and utilisation. Then combining with fuzzy theory, the environmental impact model of wind energy utilisation is constructed, the science and effectiveness of the model is validated thorough example analysis, which aims to lay a solid theoretical foundation to solve the problems of wind farm grid-connection.

Feasibility Study of Wind Energy Potential for Electricity Generation in the Northwestern Coast of Senegal  

Science Journals Connector (OSTI)

Abstract The aim of this paper is to determine the wind energy potential for electricity generation in the northwestern coast of Senegal. The wind characteristics and wind energy potential in eight sites (Kayar, Potou, Gandon, Sakhor, Sine Moussa Abdou, Botla, Dara Andal and Nguebeul) are analyzed using the wind speed data collected during a period of one year for each site. The annual mean wind speed and the power density were computed. Results obtained show that the annual mean wind speed varies between 5.28 m/s in Potou (at 30 m) and 3.10 m/s in Dara Andal (at 7 m). The corresponding power density varies between 120.01W/m2 and 30.05W/m2 respectively. A technical assessment of electricity generation from three big wind turbines and from three small wind turbines was carried out. Results show that the highest capacity factor was 39% observed in Sokhar for the wind turbine Yellow- Sand, whereas the lowest capacity factor was 5% in Gandon for the wind turbine Ecotecnia 80. The highest output energy was 4,517,900k Wh/year in Sokhar for the wind turbine Repower, while the lowest output energy was 312 kWh/year observed in Gandon for the wind turbine Inclin 600.

Measured effect of wind generation on the fuel consumption of an isolated diesel power system  

SciTech Connect

The Block Island Power Company (BIPCO), on Block Island, Rhode Island, operates an isolated electric power system consisting of diesel generation and an experimental wind turbine. The 150-kW wind turbine, designated MOD-OA by the U.S. Department of Energy is typically operated in parallel with two diesel generators to serve an average winter load of 350 kW. Wind generation serves up to 60% of the system demand depending on wind speed and total system load. Results of diesel fuel consumption measurements are given for the diesel units operated in parallel with the wind turbine and again without the wind turbine. The fuel consumption data are used to calculate the amount of fuel displaced by wind energy. Results indicate that the wind turbine displaced 25,700 lbs. of the diesel fuel during the test period, representing a calculated reduction in fuel consumption of 6.7% while generating 11% of the total electrical energy. The amount of displaced fuel depends on operating conditions and system load. It is also shown that diesel engine throttle activity resulting from wind gusts which rapidly change the wind turbine output do not significantly influence fuel consumption.

Simulation of a new grid-connected hybrid generation system with Stirling engine and wind turbine  

Science Journals Connector (OSTI)

A detail model including all mechanical and electrical aspects is necessary to fully study hybrid grid operation. In this paper a new grid-connected hybrid generation system with a Stirling engine and a wind turbine which are connected to a grid through a common dc bus is presented. The Stirling is more efficient than photo voltaic array and its combination with the wind turbine can create an efficient hybrid system. Fatigue Aerodynamics Structures and Turbulence and Simulink/MATLAB are used to model the mechanical parts of the wind turbine Stirling engine and electrical parts. Field oriented control method is developed on voltage source converter. Power signal feedback method is implemented to determine generators reference shaft speed in hybrid system. Permanent magnet synchronous generator is used in the wind turbine and Stirling engine. Simulation results show that a new hybrid generation system with Stirling and wind turbine can work like other hybrid system and has suitable performance.

Empirical Analysis of the Variability of Wind Generation in India: Implications for Grid Integration  

SciTech Connect

We analyze variability in load and wind generation in India to assess its implications for grid integration of large scale wind projects using actual wind generation and load data from two states in India, Karnataka and Tamil Nadu. We compare the largest variations in load and net load (load ?wind, i.e., load after integrating wind) that the generation fleet has to meet. In Tamil Nadu, where wind capacity is about 53percent of the peak demand, we find that the additional variation added due to wind over the current variation in load is modest; if wind penetration reaches 15percent and 30percent by energy, the additional hourly variation is less than 0.5percent and 4.5percent of the peak demand respectively for 99percent of the time. For wind penetration of 15percent by energy, Tamil Nadu system is found to be capable of meeting the additional ramping requirement for 98.8percent of the time. Potential higher uncertainty in net load compared to load is found to have limited impact on ramping capability requirements of the system if coal plants can me ramped down to 50percent of their capacity. Load and wind aggregation in Tamil Nadu and Karnataka is found to lower the variation by at least 20percent indicating the benefits geographic diversification. These findings suggest modest additional flexible capacity requirements and costs for absorbing variation in wind power and indicate that the potential capacity support (if wind does not generate enough during peak periods) may be the issue that has more bearing on the economics of integrating wind

Viability of Small Wind Distributed Generation for Farmers Who Irrigate (Poster)  

SciTech Connect

About 14% of U.S. farms are irrigated, representing 55 million acres of irrigated land. Irrigation on these farms is a major energy user in the United States, accounting for one-third of water withdrawals and 137 billion gallons per day. More than half of the Irrigation systems use electric energy. Wind energy can be a good choice for meeting irrigation energy needs. Nine of the top 10 irrigation states (California, Texas, Idaho, Arkansas, Colorado, Nebraska, Arizona, Kansas, Washington, and Oregon) have good to excellent wind resources. Many rural areas have sufficient wind speeds to make wind an attractive alternative, and farms and ranches can often install a wind energy system without impacting their ability to plant crops and graze livestock. Additionally, the rising and uncertain future costs of diesel, natural gas, and even electricity increase the potential effectiveness for wind energy and its predictable and competitive cost. In general, wind-powered electric generation systems generate more energy in the winter months than in the summer months when most crops need the water. Therefore, those states that have a supportive net metering policy can dramatically impact the viability of an onsite wind turbine. This poster presentation highlights case studies that show favorable and unfavorable policies that impact the growth of small wind in this important sector and demonstrate how net metering policies affect the viability of distributed wind generation for farmers who irrigate.

Flicker mitigation by reactive power control in wind farm with doubly fed induction generators  

Science Journals Connector (OSTI)

Abstract This paper presents a novel wind farm control with the purpose to mitigate the flicker emission of doubly fed induction generators. The presented control strategy is implemented in a wind farm connected to a distribution grid with consumers. The control system is composed by two controllers in cascade, the wind farm control and the local wind turbine controller. The wind farm control adapts itself to the consumptions of the distribution network and generates the minimal reactive power which allows smoothing the fast variations of wind power output. In this sense, the wind farm control facilitates the integration of wind farm into weak power grids by exchanging reactive power with network. Moreover, the wind farm controller has to be stable, fast and robust and the wind farm dispatch function has to guarantees that the local wind turbine controller can exchange the reactive power set point with network. This controller has been developed with the simulation tool DigSilent PowerFactory v14.1.

Fuzzy logic control strategy of wind generator based on the dual-stator induction generator  

Science Journals Connector (OSTI)

Abstract The work presented in this paper is the evaluation of the variable speed wind turbine based on dual star induction generator (DSIG) connected for power optimization in the conversion chain connected to the electrical grid. This optimization is concretized by two methods, namely, the Maximum Power Point Tracking MPPT algorithm in the case where the characteristic of the turbine is known and the nonlinear method based on the theory of fuzzy logic controlled torque which is most appropriate when there is a lack of information on the characteristic ( C p ( ? ) ) of the turbine. However, the limitation of power is performed by action on the generator control only. Simulation results are presented and discussed.

Low-Cost Superconducting Wire for Wind Generators: High Performance, Low Cost Superconducting Wires and Coils for High Power Wind Generators  

SciTech Connect

REACT Project: The University of Houston will develop a low-cost, high-current superconducting wire that could be used in high-power wind generators. Superconducting wire currently transports 600 times more electric current than a similarly sized copper wire, but is significantly more expensive. The University of Houstons innovation is based on engineering nanoscale defects in the superconducting film. This could quadruple the current relative to todays superconducting wires, supporting the same amount of current using 25% of the material. This would make wind generators lighter, more powerful and more efficient. The design could result in a several-fold reduction in wire costs and enable their commercial viability of high-power wind generators for use in offshore applications.

Making the Economic Case for Small-Scale Distributed Wind -- A Screening for Distributed Generation Wind Opportunities: Preprint  

SciTech Connect

This study was an offshoot of a previous assessment, which examined the potential for large-scale, greater than 50 MW, wind development on occupied federal agency lands. The study did not find significant commercial wind development opportunities, primarily because of poor wind resource on available and appropriately sized land areas or land use or aesthetic concerns. The few sites that could accommodate a large wind farm failed to have transmission lines in optimum locations required to generate power at competitive wholesale prices. The study did identify a promising but less common distributed generation (DG) development option. This follow-up study documents the NREL/Global Energy Concepts team efforts to identify economic DG wind projects at a select group of occupied federal sites. It employs a screening strategy based on project economics that go beyond quantity of windy land to include state and utility incentives as well as the value of avoided power purchases. It attempts to account for the extra costs and difficulties associated with small projects through the use of project scenarios that are more compatible with federal facilities and existing land uses. These benefits and barriers of DG are discussed, and the screening methodology and results are included. The report concludes with generalizations about the screening method and recommendations for improvement and other potential applications for this methodology.

A novel optimization sizing model for hybrid solar-wind power generation system  

Science Journals Connector (OSTI)

This paper develops the Hybrid Solar-Wind System Optimization Sizing (HSWSO) model, to optimize the capacity sizes of different components of hybrid solar-wind power generation systems employing a battery bank. The HSWSO model consists of three parts: the model of the hybrid system, the model of Loss of Power Supply Probability (LPSP) and the model of the Levelised Cost of Energy (LCE). The flow chart of the HSWSO model is also illustrated. With the incorporated HSWSO model, the sizing optimization of hybrid solar-wind power generation systems can be achieved technically and economically according to the system reliability requirements. A case study is reported to show the importance of the HSWSO model for sizing the capacities of wind turbines, PV panel and battery banks of a hybrid solar-wind renewable energy system.

An Optimized Autoregressive Forecast Error Generator for Wind and Load Uncertainty Study  

SciTech Connect

This paper presents a first-order autoregressive algorithm to generate real-time (RT), hour-ahead (HA), and day-ahead (DA) wind and load forecast errors. The methodology aims at producing random wind and load forecast time series reflecting the autocorrelation and cross-correlation of historical forecast data sets. Five statistical characteristics are considered: the means, standard deviations, autocorrelations, and cross-correlations. A stochastic optimization routine is developed to minimize the differences between the statistical characteristics of the generated time series and the targeted ones. An optimal set of parameters are obtained and used to produce the RT, HA, and DA forecasts in due order of succession. This method, although implemented as the first-order regressive random forecast error generator, can be extended to higher-order. Results show that the methodology produces random series with desired statistics derived from real data sets provided by the California Independent System Operator (CAISO). The wind and load forecast error generator is currently used in wind integration studies to generate wind and load inputs for stochastic planning processes. Our future studies will focus on reflecting the diurnal and seasonal differences of the wind and load statistics and implementing them in the random forecast generator.

Capacity Value of PV and Wind Generation in the NV Energy System  

SciTech Connect

Calculation of photovoltaic (PV) and wind power capacity values is important for estimating additional load that can be served by new PV or wind installations in the electrical power system. It also is the basis for assigning capacity credit payments in systems with markets. Because of variability in solar and wind resources, PV and wind generation contribute to power system resource adequacy differently from conventional generation. Many different approaches to calculating PV and wind generation capacity values have been used by utilities and transmission operators. Using the NV Energy system as a study case, this report applies peak-period capacity factor (PPCF) and effective load carrying capability (ELCC) methods to calculate capacity values for renewable energy sources. We show the connection between the PPCF and ELCC methods in the process of deriving a simplified approach that approximates the ELCC method. This simplified approach does not require generation fleet data and provides the theoretical basis for a quick check on capacity value results of PV and wind generation. The diminishing return of capacity benefit as renewable generation increases is conveniently explained using the simplified capacity value approach.

Optimal control for variable-speed wind generation systems using General Regression Neural Network  

Science Journals Connector (OSTI)

Abstract An induction generator (IG) speed drive with the application of an optimal controller and a proposed General Regression Neural Network (GRNN) controller is introduced in this paper. Grid connected wind energy conversion system (WECS) present interesting control demands, due to the intrinsic nonlinear characteristic of wind mills and electric generators. The GRNN with adaptive ant colony optimization (AACO) torque compensation is feed-forward to increase the robustness of the wind driven induction generator system. An optimal control loop for the wind power system is designed. The optimality of the whole system is defined in relation with the trade-off between the wind energy conversion maximization and the minimization of the induction generator torque variation that is responsible for the frequency fluctuations. This is achieved by using a combined optimization criterion, resulting in a LQ tracking problem with an infinite horizon and a measurable exogenous variable (wind speed). The proposed controller is designed to drive the turbine speed to extract maximum power from the wind and adjust to the power regulation.

Open Energy Info (EERE)

If I generate 20 percent of my national electricity from wind and solar - If I generate 20 percent of my national electricity from wind and solar - what does it do to my GDP and Trade Balance ? Home > Groups > DOE Wind Vision Community I think that the economics of fossil fuesl are well understood. Some gets to find the fuel and sell it. The fuel and all associated activities factor into the economic equation of the nation and the wrold. What is the economics of generating 20 percent of my total capacity from say wind? And all of it replaces coal powered electricty ? What happended to GDP ? Is the economy a net gain or net loss ? The value of the electricity came into the system, but no coal is bought or sold.

Harmonic and interharmonic distortion analysis in the grid-connected wind electric generator  

Science Journals Connector (OSTI)

The operation of wind turbines has an impact on the power quality at the connected electric network. The integration of wind electric generators with the power grid becomes a headache for power engineers in several aspects. Harmonic distortion is one of the most important phenomena which affect the grid performance. This paper provides an in-depth discussion on harmonic and interharmonic distortion taking place on the low-voltage side of the wind generator, as well as in the power grid side. A case study, to determine where a significant amount of harmonic currents or voltages exists in the system, is performed using a power quality analyser. From these measurements and subsequent calculations, the levels of harmonics and interharmonics are analysed. It is found that the harmonic distortion is invariably present on the generator side as well as on the grid side, depending on the wind turbine technology.

Stabilisation of grid connected wind farms using doubly-fed induction generators with FACTS controllers  

Science Journals Connector (OSTI)

The impact of the wind generation on the power systems is no longer negligible if high penetration levels are going to be achieved. It is very important to boost the transfer capability of the transmission system while improving the utilisation of transmission assets to accommodate high penetration of wind power on the network. Hence, more sophisticated control schemes using advanced power electronic-based flexible AC transmission system (FACTS) controllers are required which will enhance voltage security and voltage stability control. This paper presents the impact of FACTS controllers on the dynamic stability of power systems connected with wind energy conversion systems. The wind farm model considered is a variable speed doubly-fed induction generator model. The dynamic simulation results yield information on: 1) the impact of faults and wind speed changes on the performance of DFIG-based induction generators; 2) the change in controllable parameters of the FACTS controllers following the faults and wind speed changes; 3) transient rating of the FACTS controllers for enhancement of rotor speed stability of induction generators and angle stability of synchronous generators.

Unit commitment with wind power generation: integrating wind forecast uncertainty and stochastic programming.  

SciTech Connect

We present a computational framework for integrating the state-of-the-art Weather Research and Forecasting (WRF) model in stochastic unit commitment/energy dispatch formulations that account for wind power uncertainty. We first enhance the WRF model with adjoint sensitivity analysis capabilities and a sampling technique implemented in a distributed-memory parallel computing architecture. We use these capabilities through an ensemble approach to model the uncertainty of the forecast errors. The wind power realizations are exploited through a closed-loop stochastic unit commitment/energy dispatch formulation. We discuss computational issues arising in the implementation of the framework. In addition, we validate the framework using real wind speed data obtained from a set of meteorological stations. We also build a simulated power system to demonstrate the developments.

Wind turbine generator interaction with conventional diesel generators on Block Island, Rhode Island. Volume 1. Executive summary  

SciTech Connect

This report summarizes the primary results of a three-part study involving the effects of connecting a MOD-OA wind turbine generator to an isolated diesel power system. The subject utility is that owned and operated by the Block Island Power Company (BIPCO). The MOD-OA installation here was the third of four experimental nominal 200 kW wind turbines connected to various utilities under the Federal Wind Energy Program. The BIPCO installation was characterized by the highest wind energy penetration levels of four sites and, as such, was adjudged the best candidate for conducting the data acquisition and analysis effort that is the subject of this study. The three-phases of the study analysis address: (1) fuel displacement, (2) dynamic interaction, and (3) three modes of reactive power control. These analyses all have as their basis the results of the data acquisition program conducted during 1982 from February into April on Block Island, Rhode Island.

Wind turbine generator interaction with conventional diesel generators on Block Island, Rhode Island. Volume II. Data analysis  

SciTech Connect

In order to assess the performance of a MOD-OA horizontal axis wind turbine when connected to an isolated diesel utility, a comprehensive data measurement program was conducted on the Block Island Power Company installation on Block Island, Rhode Island. This report presents the detailed results of that program focusing on three principal areas of (1) fuel displacement (savings), (2) dynamic interaction between the diesel utility and the wind turbine, (3) effects of three modes of wind turbine reactive power control. The approximate two month duration of the data acquisition program conducted in the winter months (February into April 1982) revealed performance during periods of highest wind energy penetration and hence severity of operation. It is concluded that even under such conditions fuel savings were significant resulting in a fuel reduction of 6.7% while the MOD-OA was generating 10.7% of the total electrical energy. Also, electrical disturbance and interactive effects were of an acceptable level.

Status of Power Generation by Domestic Scale Wind Turbines in Australia  

Science Journals Connector (OSTI)

The world's fossil fuel energy resources are diminishing at a faster rate and most importantly the liquid fossil fuel is expected to be finished by 2060s. Moreover, the fossil fuel is directly related to air pollution, land and water degradation. The danger of climate change due to global warming caused by greenhouse gas emissions compels the policy makers, scientists and researchers globally to explore power generation from renewable sources such as wind. Despite significant progresses have been made in power generation using large scale wind turbines recently, domestic scale wind turbines that have immense potentials for standalone power generation are not explored and adequately researched. Therefore, the primary objective of this study is to review and analyse the potentials for power generation by domestic scale wind turbines for the residential and semi-commercial applications. The study reviews the current status of wind characteristics in built-up areas, economic feasibility, aerodynamic and technological limits, local government planning requirement, local and foreign small scale wind turbine manufacturers.

The development and application practice of windsolar energy hybrid generation systems in China  

Science Journals Connector (OSTI)

China is the largest developing country in the world. At present, more and more energy demand gives immense pressure to Chinese government. The inappropriate energy structure must be improved by Chinese government in order to achieve the sustainable development of economy and society. Development and application of renewable energy, such as wind energy, solar energy, biomass energy, etc., have been regarded by the government and the local people in the past 10 years, and more and more actual examples have been established, which are supported by government and plants in China. It is well known that there are abundant wind and solar resources in China. This paper presents the distribution zone and development and application practice status in China. However, a common drawback is existing in the stand-alone wind energy and solar energy generating power system, which is the unpredictable output electric power, and the output power depends on the unpredictable weather and climatic changes. Fortunately, the windsolar hybrid generation system can partially overcome the problems. The conventional structure and key technology of stand-alone windsolar hybrid generating system, the current status and outlook of windsolar hybrid energy system are presented in the paper, for example, the city road lighting system, distributed generation, photovoltaic (PV) water pumping for irrigation, etc. At the end, the policies and laws of China central government and local governments are described, and the development barriers and recommendations are introduced.

Probabilistic tuning of Power System Stabilizers considering the wind farm generation uncertainty  

Science Journals Connector (OSTI)

Abstract The increasing use of wind farms and the uncertainties in their generation levels have led to new challenges in system dynamic behaviors and Small Signal Stability (SSS). This paper proposes a probabilistic method to investigate the impact of the wind farm generation uncertainty on power system SSS, based on the Monte Carlo simulation. The proposed method is stochastic in contrast to conventional deterministic methods, which only analyze the system dynamic behaviors in one operating point. It determines several operating points, based on wind farm generation levels and calculates the Probability Density Function (PDF) of critical eigenvalues. Then, Genetic Algorithm (GA) is used to optimize the Power System Stabilizers (PSS) parameters. A case study is carried out on the IEEE 16-machine system to demonstrate the effectiveness and validity of the proposed algorithms. The results of probabilistic stability analysis are compared with those of deterministic analysis. It is shown that variation of the wind farm generation levels can cause the instability, even though the system is stable according to the deterministic analysis. Also, the time domain simulation results show how such tunings can effectively improve the SSS performance under the wind farm generation uncertainties.

Characteristic Requirements of a Small Scale Squirrel Cage Induction Generator for Effective Electricity Generation from Wind Energy  

Science Journals Connector (OSTI)

Abstract This paper proposes characteristic requirements of a small scale squirrel cage induction generator for effective electricity generation from wind energy. These characteristics are obtained from modeling and testing results. Investigation into comparative performances between Standard and high efficiency induction generators is given in order to find out the characteristic requirements of a suitable induction generator. Performances of various features of the machine structure are given. The suitable design of the induction generator based on empirical rules is also included. The investigation of power loss of the induction machine both in theory using FEM (Finite Element Method) and tests has been made. In addition, static var (Volt-Ampere reactive power) compensator using power electronic control to keep terminal voltage of a self-excited induction generator constant is explained. These results can be guidelines for machine development and control method for effective electricity generation.

Assessment of Wind/Solar Co-located Generation in Texas  

SciTech Connect

This paper evaluates the opportunity to load co-located wind and solar generation capacity onto a constrained transmission system while engendering only minimal losses. It quantifies the economic and energy opportunities and costs associated with pursuing this strategy in two Texas locations ?¢???? one in west Texas and the other in south Texas. The study builds upon previous work published by the American Solar Energy Society (ASES) which illuminated the potential benefits of negative correlation of wind and solar generation in some locations by quantifying the economic and energy losses which would arise from deployment of solar generation in areas with existing wind generation and constrained transmission capacity. Clean Energy Associates (CEA) obtained and incorporated wind and solar resource data and the Electric Reliability Council of Texas (ERCOT)) load and price data into a model which evaluates varying levels of solar thermal, solar photovoltaic (PV) and wind capacity against an assumed transmission capacity limit at each of the two locations.

Floating axis wind turbines for offshore power generationa conceptual study  

Science Journals Connector (OSTI)

The cost of energy produced by offshore wind turbines is considered to be higher than land based ones because of the difficulties in construction, operation and maintenance on offshore sites. To solve the problem, we propose a concept of a wind turbine that is specially designed for an offshore environment. In the proposed concept, a floater of revolutionary shape supports the load of the wind turbine axis. The floater rotates with the turbine and the turbine axis tilts to balance the turbine thrust, buoyancy and gravity. The tilt angle is passively adjustable to wind force. The angle is 30 at rated power. The simplicity of the system leads to further cost reduction of offshore power generation.

Impacts of Wind and Solar on Fossil-Fueled Generators: Preprint  

SciTech Connect

High penetrations of wind and solar power will impact the operations of the remaining generators on the power system. Regional integration studies have shown that wind and solar may cause fossil-fueled generators to cycle on and off and ramp down to part load more frequently and potentially more rapidly. Increased cycling, deeper load following, and rapid ramping may result in wear-and-tear impacts on fossil-fueled generators that lead to increased capital and maintenance costs, increased equivalent forced outage rates, and degraded performance over time. Heat rates and emissions from fossil-fueled generators may be higher during cycling and ramping than during steady-state operation. Many wind and solar integration studies have not taken these increased cost and emissions impacts into account because data have not been available. This analysis considers the cost and emissions impacts of cycling and ramping of fossil-fueled generation to refine assessments of wind and solar impacts on the power system.

Strategic selection of suitable projects for hybrid solar-wind power generation systems  

Science Journals Connector (OSTI)

Because of the pressing need for maintaining a healthy environment with reasonable costs, China is moving toward the trend for generating electricity from renewable resources. Both solar energy and wind power have received a tremendous attention from private associations, political groups, and electric power companies to generate power on a large scale. A drawback is their unpredictable nature and dependence on weather. Fortunately, the problems can be partially tackled by using the strengths of one source to overcome the weakness of the other. Especially, a large fraction of the solar resource is available at times of peak electrical load. However, the complexity of using two different resources together makes the hybrid solar-wind generation systems more difficult to analyze. Accordingly, this paper first briefly introduces the solar-wind generation system and next develops its critical success criteria. Then, a fuzzy analytic hierarchy process associated with benefits, opportunities, costs and risks, is proposed to help select a suitable solar-wind power generation project.

Impacts of dynamic reactive power compensation devices on the performance of wind power generators  

Science Journals Connector (OSTI)

This paper investigates the main impacts of dynamic reactive power compensation devices on the performance of induction machine-based wind power generators. The dynamic reactive power compensation devices analysed are the SVC (Static Var Compensator) and the DSTATCOM (Distributed Static Synchronous Compensator). The usage of these devices as a power factor regulator or a voltage regulator is investigated. The technical factors analysed are small-signal voltage stability, transient stability and interactions with the anti-islanding protection system. The analyses are carried out by using a wind farm composed of 30 units of 1 MW induction generators. Such wind farm is connected to a 60 Hz, 33 kV distribution system. The results are a useful guideline to evaluate which control strategy and device are suitable for a determined application as well as to understand the dynamic interactions that can occur.

Security constrained generation scheduling for grids incorporating wind, photovoltaic and thermal power  

Science Journals Connector (OSTI)

Abstract In this paper, security constrained generation scheduling (SCGS) problem for a grid incorporating thermal, wind and photovoltaic (PV) units is formulated. The formulation takes into account the stochastic nature of both wind and PV power output and imbalance charges due to mismatch between the actual and scheduled wind and PV power outputs. A hybrid technique in which the basic elements are a genetic algorithm (GA) with artificial neural network (ANN) and a priority list (PL) is used to minimize the total operating costs while satisfying all operational constraints considering both conventional and renewable energy generators. Numerical results are reported and discussed based on the simulation performed on the IEEE 24-bus reliability test system. The results demonstrate the efficiency of the proposed approach to reduce the total production cost for real time operation. Moreover, the results verified that the proposed approach can be applied to different problem dimensions and can score more favorably compared with analytical techniques.

A concept of power generator using wind turbine, hydrodynamic retarder, and organic Rankine cycle drive  

Science Journals Connector (OSTI)

This paper describes a concept of electric power generating system that uses a wind turbine to generate kinetic energy which converts heat through a hydrodynamic retarder. The heat so generated is utilized to drive an organic Rankine cycle that converts thermal energy into electricity power for continuous and undisrupted supply during the year. A hydrodynamic retarder converts kinetic energy into heat through hot fluid by directing the flow of the fluid into the hydrodynamic retarder in a manner that resists rotation of blades of the wind turbine. The hot fluid circulating in the hydrodynamic retarder is a thermal heat source for vapor regeneration of organic heat exchange fluid mixture(s) used in the Rankine cycle. The expansion of the organic heat exchange fluid gets converted into rotation of the generator rotor.

This paper presents a sliding mode control (SMC) associated to the field oriented control (FOC) of a dual-stator induction generator (DSIG) based wind energy conversion systems (WECSs). The DSIG has two sets of stator three-phase windings spatially shifted by 30 electrical degrees. The study of operation of the wind turbine leads us to two essential cases: optimization of the power for wind speeds lower than the nominal speed of the turbine and limitation of the power for higher speeds. Conventional electrical grid connected WECS present interesting control demands, due to the intrinsic nonlinear characteristic of wind mills and electric generators. The SMC is a robust nonlinear algorithm which uses discontinuous control to force the system states trajectories to join some specified sliding surface, it has been widely used for its robustness to model parameter uncertainties and external disturbances, is studied. In order to verify the validity of the proposed method, a dynamic model of the proposed system has been simulated, to demonstrate its performance.

Variable susceptance excitation control for dynamic performance improvement of a stand-alone wind turbine induction generator system  

Science Journals Connector (OSTI)

Isolated wind farms employ simple squirrel cage induction generators driven by variable speed wind turbines. Lacking control capability, such generation can contribute very little to network support. Wind turbines mostly do not take part in voltage and frequency control and if a disturbance occurs, the turbines may be disconnected and reconnected when normal operation has been resumed. From operation viewpoint, this is definitely not acceptable. A primary reason for the rigidity of operation is the lack of excitation adaptation under variable wind conditions. This article proposes incorporation of a variable capacitance controller at the generator terminal which will automatically adjust the needed excitation. Further improvement of transient profile of the stand-alone wind turbine generator has been proposed through inclusion of additional stabilising control. Simulation studies show that the proposed excitation controller with additional PID circuit provides very good transient profile following reasonable input torque variations.

Evaluation of distributed building thermal energy storage in conjunction with wind and solar electric power generation  

Science Journals Connector (OSTI)

Abstract Energy storage is often seen as necessary for the electric utility systems with large amounts of solar or wind power generation to compensate for the inability to schedule these facilities to match power demand. This study looks at the potential to use building thermal energy storage as a load shifting technology rather than traditional electric energy storage. Analyses are conducted using hourly electric load, temperature, wind speed, and solar radiation data for a 5-state central U.S. region in conjunction with simple computer simulations and economic models to evaluate the economic benefit of distributed building thermal energy storage (TES). The value of the TES is investigated as wind and solar power generation penetration increases. In addition, building side and smart grid enabled utility side storage management strategies are explored and compared. For a relative point of comparison, batteries are simulated and compared to TES. It is found that cooling TES value remains approximately constant as wind penetration increases, but generally decreases with increasing solar penetration. It is also clearly shown that the storage management strategy is vitally important to the economic value of TES; utility side operating methods perform with at least 75% greater value as compared to building side management strategies. In addition, TES compares fairly well against batteries, obtaining nearly 90% of the battery value in the base case; this result is significant considering TES can only impact building thermal loads, whereas batteries can impact any electrical load. Surprisingly, the value of energy storage does not increase substantially with increased wind and solar penetration and in some cases it decreases. This result is true for both TES and batteries and suggests that the tie between load shifting energy storage and renewable electric power generation may not be nearly as strong as typically thought.

Decoupled Control of Doubly Fed Induction Generator by Vector Control for Wind Energy Conversion System  

Science Journals Connector (OSTI)

Abstract Since the penetration of wind power generation in growing, system operators have an increasing interest in analyzing the impact of wind power on the connected power system. The doubly fed induction generator (DFIG) is generally used in the production of the electric energy and more specifically in wind turbines. Currently, to regulate the active and reactive power exchanged between the machine and the grid. A detail dynamic model of a DFIG-based wind-turbine grid-connected system is presented in the d,q -synchronous reference frame by controlling the machine inverter with the algorithm of control based on vector control concept (with stator flux orientation). The aim of control is to have measured active and reactive powers equal to the reference values. These powers must then be collected. In order to measure only the rotor currents, we can use an indirect control method, with integrating power regulation loop, using a classical PI controller: proportionalintegral. In this way, this control is able to limit the machine rotor currents. In another way, an appropriate fitness function is derived to express the time domain evolution of DFIG, with the objective to assure the DFIG continuous operation even under a fault condition and improve at the same time its transient behavior as compared with the indirect control without power loop. The control of our machine is simulated; finally the Simulations results are presented and discussed.

On the exergetic capacity factor of a wind solar power generation system  

Science Journals Connector (OSTI)

In the recent years, exergy analysis has become a very important tool in the evaluation of systems' efficiency. It aims on minimizing the energy related-system losses and therefore maximizing energy savings and helps society substantially to move towards sustainable development and cleaner production. In this paper, a detailed exergetic analysis aiming to identify the overall Exergetic Capacity Factor (ExCF) for a wind solar power generation system was done. ExCF, as a new parameter, can be used for better classification and evaluation of renewable energy sources (RES). All the energy and exergy characteristics of wind and solar energy were examined in order to identify the variables that affect the power output of the hybrid system. A validated open source PV optimization tool was also included in the analysis, It was shown that parameters as e.g. air density or tracking losses, low irradiation losses play a crucial role in identifying the real and net wind and solar power output while planning new renewable energy projects and in fact do play a significant role on the wind solar plant's overall exergetic efficiency. In specific, it was found that air density varies from site to site influencing productivity. A difference of 6.2% on the productivity because of the air density was calculated. The wind and solar potential around a mountainous area were studied and presented based on field measurements and simulations. Since the number and the size of RES projects, over the last few years, are continually increasing, and new areas are required, the basic idea behind this research, was not only to introduce ExCF, as a new evaluation index for RES, but also to investigate the combined use of wind and solar energy under the same area and the benefits coming out of this combination.

Comparative Assessment of Direct Drive High Temperature Superconducting Generators in Multi-Megawatt Class Wind Turbines  

SciTech Connect

This paper summarizes the work completed under the CRADA between NREL and American Superconductor (AMSC). The CRADA combined NREL and AMSC resources to benchmark high temperature superconducting direct drive (HTSDD) generator technology by integrating the technologies into a conceptual wind turbine design, and comparing the design to geared drive and permanent magnet direct drive (PMDD) wind turbine configurations. Analysis was accomplished by upgrading the NREL Wind Turbine Design Cost and Scaling Model to represent geared and PMDD turbines at machine ratings up to 10 MW and then comparing cost and mass figures of AMSC's HTSDD wind turbine designs to theoretical geared and PMDD turbine designs at 3.1, 6, and 10 MW sizes. Based on the cost and performance data supplied by AMSC, HTSDD technology has good potential to compete successfully as an alternative technology to PMDD and geared technology turbines in the multi megawatt classes. In addition, data suggests the economics of HTSDD turbines improve with increasing size, although several uncertainties remain for all machines in the 6 to 10 MW class.

Current status of research on optimum sizing of stand-alone hybrid solarwind power generation systems  

Science Journals Connector (OSTI)

Solar and wind energy systems are omnipresent, freely available, environmental friendly, and they are considered as promising power generating sources due to their availability and topological advantages for local power generations. Hybrid solarwind energy systems, uses two renewable energy sources, allow improving the system efficiency and power reliability and reduce the energy storage requirements for stand-alone applications. The hybrid solarwind systems are becoming popular in remote area power generation applications due to advancements in renewable energy technologies and substantial rise in prices of petroleum products. This paper is to review the current state of the simulation, optimization and control technologies for the stand-alone hybrid solarwind energy systems with battery storage. It is found that continued research and development effort in this area is still needed for improving the systems performance, establishing techniques for accurately predicting their output and reliably integrating them with other renewable or conventional power generation sources.

Generation risk assessment in volatile conditions with wind, hydro, and natural gas units  

Science Journals Connector (OSTI)

This paper studies a generating company (GENCO)s midterm (a few months to a year) scheduling payoffs and risks in volatile operating conditions. The proposed algorithm considers the integration of intermittent wind units into a GENCOs generation assets and coordinates the GENCOs hourly wind generation schedule with that of natural gas (NG) units (with volatile gas prices) and hydro units (with water inflow forecast) for maximizing the GENCOs payoff. The proposed midterm GENCO model applies market price forecasts to the risk-constrained stochastic price-based unit commitment (PBUC) for calculating the GENCOs risk in energy and ancillary services markets. The proposed PBUC minimizes the cost of (a) NG contracts, storage, startup and shutdown, (b) startup and shutdown of cascaded hydro units, and (c) penalty for defaulting on the scheduled power delivery. Simulation results show that the diversification of generating assets including bilateral contracts (BCs) could enhance the GENCOs midterm planning by increasing the expected payoff and decreasing the financial risk.

Variable Structure Control of a Doubly Fed Induction Generator for Wind Energy Conversion Systems  

Science Journals Connector (OSTI)

Abstract This paper presents the powers control of a variable speed wind turbine (WT) device based on a doubly fed induction generator (DFIG). Indeed, to increase the efficiency of the WT system, a robust variable structure control has been applied. DFIG has been previously presented in several works with diverse control diagrams using generally conventional PI controllers. Nevertheless, this type of controllers does not sufficiently handle some of WT resource characteristics such as wind fluctuations effects. Indeed, these can reduce WT performances. Furthermore, DFIG parameter variations should be accounted for. In this context, this paper proposes a high-order sliding mode to control the WT DFIG. Simulation results show that the proposed approach presents attractive features such as chattering-free behavior, good response to speed variations and robustness against machine parameter variations compared to the conventional first order sliding mode technique and even fuzzy sliding mode one.

Steady-state analysis of doubly fed induction generators for wind turbines using MATLAB  

Science Journals Connector (OSTI)

A wind energy conversion system (WECS) differs from a conventional power system. The power output of a conventional power plant can be controlled whereas; the power output of a WECS depends on the wind. This nature of WECS makes it difficult for analysis, design and management. Various approaches have been developed to study the behaviour of WECS. In this paper, the steady-state characteristics of a WECS using doubly fed induction generators (DFIG) are analysed using MATLAB. The dynamic steady-state simulation model of the DFIG is developed using MATLAB. Simulation analysis is performed to investigate a variety of DFIG characteristics, including torque-speed, real and reactive-power over speed characteristics. Based on the analysis, the DFIG operating characteristics are studied.

Statistics for PV, wind and biomass generators and their impact on distribution grid planning  

Science Journals Connector (OSTI)

The integration of renewable energy generation leads to major challenges for distribution grid operators. When the feed-in of photovoltaic (PV), biomass and wind generators exceed significantly the local consumption, large investments are needed. To improve the knowledge on the interaction between these technologies, statistical information for load curves, correlation coefficients and general feed-in behavior is derived. These derivations are based on measured data of different generators in a German distribution area. In this paper, we give new insights useful for the dimensioning of grid structures and assets. Furthermore, an approach is presented which allows the calculation of the maximum and minimum feed-in resulting from different combinations of the considered technologies.

Grid Connected based PWM Converter Applied a Self-excited Induction Generator for Wind Turbine Applications  

Science Journals Connector (OSTI)

Abstract This paper presents the electrical power conversion system which is developed for a self-excited induction generator in order to apply with wind turbine. In the wind energy conversion system, a self-excited induction generator is converted the mechanical energy into electrical energy. A B6 rectifier and capacitor are utilized to maintain constant intermediate DC voltage. The average power is converted entirely by the PWM converter, consists of B6 voltage-source inverters. Output currents and active power of switch mode voltage source inverter are flowed into utility grid by current control and PQ theory technique. For the hardware implementation, the system consists of 1kW four poles self excited induction generator and the voltage source inverter controlled output current by hysteresis controller(bang-bang) method. The algorithm is implemented in a dSPACS ds1104DSP together with MATLAB/SIMULINK program. The validity of the proposed method is verified by both simulation and experimental results under power transferred into grid in term of power quality such as real power, reactive power, total harmonics distortion, and so on.

Fluid power network for centralized electricity generation in offshore wind farms  

Science Journals Connector (OSTI)

An innovative and completely different wind-energy conversion system is studied where a centralized electricity generation within a wind farm is proposed by means of a hydraulic network. This paper presents the dynamic interaction of two turbines when they are coupled to the same hydraulic network. Due to the stochastic nature of the wind and wake interaction effects between turbines, the operating parameters (i.e. pitch angle, rotor speed) of each turbine are different. Time domain simulations, including the main turbine dynamics and laminar transient flow in pipelines, are used to evaluate the efficiency and rotor speed stability of the hydraulic system. It is shown that a passive control of the rotor speed, as proposed in previous work for a single hydraulic turbine, has strong limitations in terms of performance for more than one turbine coupled to the same hydraulic network. It is concluded that in order to connect several turbines, a passive control strategy of the rotor speed is not sufficient and a hydraulic network with constant pressure is suggested. However, a constant pressure network requires the addition of active control at the hydraulic motors and spear valves, increasing the complexity of the initial concept. Further work needs to be done to incorporate an active control strategy and evaluate the feasibility of the constant pressure hydraulic network.

Adaptive second order sliding mode control of doubly fed induction generator in wind energy conversion system  

Science Journals Connector (OSTI)

A dynamic synchronous d-q reference frame based modeling and a novel adaptive higher order sliding mode control theory for doubly fed induction generator (DFIG) based wind energy conversion system (WECS) have been proposed in this paper. As depicted from the literature the sliding mode control strategy involving computation of converter currents introduces some inaccuracies for optimal extraction of the power references of the DFIG. On the contrary the proposed method contributes with some important features such as chatter-free performance and heftiness in terms of transient response of the non-linear systems subjected to dynamic conditions such as lower and higher wind speeds. Consequently a higher order sliding mode controller using the active and reactive power of the DFIG as controller inputs has been proposed in this paper. As compared with the other two methods the proposed higher order sliding mode power control souvenirs a significantly improved as well as stable performance of the DFIG based WECS in terms of reduced settling time as well as quickly damping out the oscillations exhibited by the system. The robustness and stability of the proposed control strategy has been validated in MATLAB environment in terms of the comparison of its performance with traditional proportional-integral and existing first-order sliding mode controller (employing converter current as input) subjected to a wide range of disturbances for sub and super synchronous mode of operation of the DFIG subjected to lower and higher wind speeds along with the available practical wind speed data as depicted in the simulation and result section.

Conventional wind energy systems are limited in wind turbine diameter by allowable rotor stresses at power levels of several megawatts. In contrast, the Electrofluid Dynamic (EFD) wind driven generator has no fundamental limits on cross sectional area. It is a direct energy conversion device which employs unipolar charged particles transported by the wind against a retarding voltage gradient to a high potential. As no moving parts are exposed to the wind, extremely large power units may be feasible.

We have adapted our model of surface?generated noise in a stratified lossy ocean to the case of low?frequency wind?generated noise produced in deep water by turbulentpressure fluctuations in the atmosphere. The model assumes a random pressure distribution at the surface and includes the effects of sound?speed profile and bottom characteristics. Using Wilson's source levels [J. H. Wilson J. Acoust. Soc. Am. 66 14991507 (1979)] we have calculated the noise level as functions of frequency and depth and compared the results with measured data. We show these results along with calculations of the spatial coherence function which differs significantly from the standard deep?water result. Finally we present calculations of the effective surface area that is the area of the surface centered above the receiver which contributes most of the noise intensity. We show that this quantity is dependent on receiver depth.

Predictive current control of outer-rotor five-phase BLDC generators applicable for off-shore wind power plants  

Science Journals Connector (OSTI)

Abstract Model predictive control algorithms have recently gained more importance in the field of wind power generators. One of the important categories of model predictive control methods is improved deadbeat control in which the reverse model of generator is used to calculate the appropriate inputs for the next iteration of controlling process. In this paper, a new improved deadbeat algorithm is proposed to control the stator currents of an outer-rotor five-phase BLDC generator. Extended Kalman filter is used in the estimation step of proposed method, and generator equations are used to calculate the appropriate voltages for the next modulation period. Two aspects of proposed controlling method are evaluated including its sensitivity to generator parameter variations and its speed in following the reference values of required torque during transient states. Wind power generators are kept in mind, and proposed controlling method is both simulated and experimentally evaluated on an outer-rotor five-phase BLDC generator.

Protection from ground faults in the stator winding of generators at power plants in the Siberian networks  

SciTech Connect

The experience of many years of experience in developing and utilization of ground fault protection in the stator winding of generators in the Siberian networks is generalized. The main method of protection is to apply a direct current or an alternating current with a frequency of 25 Hz to the primary circuits of the stator. A direct current is applied to turbo generators operating in a unit with a transformer without a resistive coupling to the external grid or to other generators. Applying a 25 Hz control current is appropriate for power generation systems with compensation of a capacitive short circuit current to ground. This method forms the basis for protection of generators operating on busbars, hydroelectric generators with a neutral grounded through an arc-suppression reactor, including in consolidated units with generators operating in parallel on a single low-voltage transformer winding.

Use of Solar and Wind as a Physical Hedge against Price Variability within a Generation Portfolio  

SciTech Connect

This study provides a framework to explore the potential use and incremental value of small- to large-scale penetration of solar and wind technologies as a physical hedge against the risk and uncertainty of electricity cost on multi-year to multi-decade timescales. Earlier studies characterizing the impacts of adding renewable energy (RE) to portfolios of electricity generators often used a levelized cost of energy or simplified net cash flow approach. In this study, we expand on previous work by demonstrating the use of an 8760 hourly production cost model (PLEXOS) to analyze the incremental impact of solar and wind penetration under a wide range of penetration scenarios for a region in the Western U.S. We do not attempt to 'optimize' the portfolio in any of these cases. Rather we consider different RE penetration scenarios, that might for example result from the implementation of a Renewable Portfolio Standard (RPS) to explore the dynamics, risk mitigation characteristics and incremental value that RE might add to the system. We also compare the use of RE to alternative mechanisms, such as the use of financial or physical supply contracts to mitigate risk and uncertainty, including consideration of their effectiveness and availability over a variety of timeframes.

In this paper, the flow physics of \\{VGs\\} and how their size affects the aerodynamic performance of a blunt trailing-edge airfoil DU97-W-300 have been investigated using CFD simulations. Based on wind turbine dedicated airfoil with and without \\{VGs\\} respectively, three-dimensional numerical models were established and further validated through the comparisons between the numerical results and the experimental data. The effects of VGs' size were analyzed from several perspectives, such as trailing-edge height, length, short and long spacing between an adjacent pair of VGs. The results indicate that drag penalty is more sensitive to the increase of VG height than lift; an increment of VG length leads to negative effects on both lift and drag; increases of the spacing between an adjacent pair of \\{VGs\\} have positive impact on suppression of separated flow. Additionally, the flow field characteristics were further revealed by the analysis of streamlines and vortices in the wake region.

Supercapacitor energy storage system for fault ride-through of a DFIG wind generation system  

Science Journals Connector (OSTI)

The doubly fed induction generators (DFIGs) are preferred over other variable speed generators because of their advantages in terms of economy and control. One of the problems associated with high wind power penetration DFIG systems, however, is the inability of their converters to work properly under extreme low voltage conditions. This article presents a decoupled PQ control strategy of a supercapacitor energy storage system, interfaced through a STATCOM, for low voltage ride through as well as damping enhancement of the DFIG system. The STATCOM meets the reactive power need under the depressed voltage condition, while the supercapacitor caters to the real power unbalance. An extensive dynamic model of the DFIG system including a supercapacitor DCDC buckboost converter and the STATCOM circuit has been developed. The fault ride-thorough capability of the generator has been investigated for a severe symmetrical three-phase to ground fault on the grid bus. Simulation results suggest that the proposed decoupled control of the supercapacitor STATCOM control strategy can help the DFIG ride through extreme low voltage conditions for significant duration. The proposed control strategy also damps the electromechanical transients, and thus quickly restores normal operation of the converters.

Simulation of Sensor Fault Diagnosis for Wind Turbine Generators DFIG and PMSM Using Kalman Filter  

Science Journals Connector (OSTI)

Abstract The fault detection and isolation of generators used in wind turbines gathering interest as to maximize the reliability and avail of distributed energy systems with recent unmatched growth in construction of offshore wind farms. In particular it is interested in performing fault detection and isolation (FDI) of incipient faults affecting the measurements of the three-phase signals (currents) in a controlled DFIG and PMSG. Although different authors have dealt with FDI for sensors in induction machines and in DFIGs, most of them rely on the machine model with constant parameters. However, the parameter uncertainties due to changes in the operating conditions will produce degradation in the performance of such FDI systems. The robust techniques to detect faults are exist but there is a need of extra sensor. This paper proposed a systematic methodology for the design of sensor FDI systems with the following characteristics: i) capable of detecting and isolating incipient additive (bias) faults, ii) robust against changes in the references/disturbances affecting the controlled DFIG and PMSG as well as modeling/parametric uncertainties, iii) residual generation system based on a multi-observer strategy to enhance the isolation process, The designed sensor FDI systems have been validated using measured voltages, as well as simulated data from a controlled DFIG. First the state space models of DFIG and PMSM explained followed by kalman filter introduction and current sensor fault detection using a bank of kalman filter named dedicated Observer Scheme and generalized Observer scheme to detect simultaneous and multiple faults was theorized and simulated using MATLAB simulation tool .The simulation results were summarized with and without Sensor fault.

An intelligent neuro-fuzzy logic controller for induction generator based wind generation to improve power system stability  

Science Journals Connector (OSTI)

Power systems are non-linear and they are often subjected to random disturbances. This paper deals with the application of the intelligent neuro-fuzzy technique to the design of the robust power system stabiliser for power system oscillation damping enhancement in a wind turbine based power system network. The stabilising signal is computed in real time using suitable fuzzy membership functions depending upon the state of the generator on the speed-acceleration phase plane. These input signals are first characterised by a set of linguistic variables using fuzzy set notations. The fuzzy relation matrix, which gives the relationship between stabiliser inputs and stabiliser output, allows a set of fuzzy logic operations that are performed on stabiliser inputs to obtain the desired stabiliser output. The performance of the proposed controller is analysed in a single induction machine-infinite bus power system data subjected to various dynamic and transient disturbances. The proposed intelligent neuro-fuzzy control scheme exhibits a superior damping performance in comparison to the conventional controllers. Its simple architecture reduces the computational burden, thereby making it attractive for real-time implementation.

Materials use in electricity generators in wind turbines state-of-the-art and future specifications  

Science Journals Connector (OSTI)

Abstract The European Strategic Energy Technology Plan, adopted by the European Union in 2008, is a first step to establish an energy technology policy for Europe and to support the 2020 energy and climate change targets from the technology development point of view. One of its initiatives is to assess the characteristics of the materials that will be needed in order to achieve the 2020 targets, in terms both of amounts of materials and their technical specifications, along with the way to get there for the latter. The Materials Initiative was created to foster a roadmap which is based on a scientific assessment of the current situation. This paper presents the work of the author in the (wind turbine) electricity generator part of that assessment, it includes the aspects of technology and system state-of-the-art; material supply status; on-going research and players; materials specification targets for 2020/2030 and beyond. The assessment found that the performance of permanent magnets is the single item potentially to provide the most significant improvement in component specification, but that in order to achieve this perhaps new chemical components based on rare earths, as currently, or not-will be necessary in order to achieve these high-performance magnets. The search for these new materials is stimulated by the current dependency of the world in a nearly-monopolistic supplier of rare earth elements. The assessment also concluded that the improvement of materials specifications is challenging but achievable in most areas, and a crucial aspect for the necessary cost reductions in wind energy production.

Effect of wind generation system types on Micro-Grid (MG) fault performance during both standalone and grid connected modes  

Science Journals Connector (OSTI)

Abstract Recently, there are three wind generation (WG) system types. The first type is called Fixed Speed Wind Generation (FSWG) system, which employs squirrel cage induction generators. Double Fed Induction Generator (DFIG) is utilized in the second type. The third type is called Full Converter Wind Generation (FCWG) system, which is interfaced with Micro-Grid (MG) through a back to back converter. During fault occurrence, each WG has its performance and characteristics which are determined by the generator physical characteristics and the MG earthing system configuration. For some WG types, the fault current depends also on the control algorithm of the power converter. The main target of this paper is to investigate and estimate how the fault performance of MG during both standalone and grid-connected modes is influenced by the type of WG. It is found during standalone mode that the type of the employed WG has a dominant impact on the MG performance under fault disturbance. On the contrary, the type of the employed WG has a negligible effect on the MG fault performance during grid-connected mode. This is because the main grid contributes most of the fault current. Effects of earthing system type on MG performance are highlighted.

Modular Isotopic Thermoelectric Generator (MITG) Design and Development, Part A-E. Original was presented at 1983 Intersociety Energy Conversion Engineering Conference (IECEC)  

SciTech Connect

Advanced RTG concepts utilizing improved thermoelectric materials and converter concepts are under study at Fairchild for DOE. The design described here is based on DOE's newly developed radioisotope heat source, and on an improved silicon-germanium material and a multicouple converter module under development at Syncal. Fairchild's assignment was to combine the above into an attractive power system for use in space, and to assess the specific power and other attributes of that design. The resultant design is highly modular, consisting of standard RTG slices, each producing 24 watts at the desired output voltage of 28 volt. Thus, the design could be adapted to various space missions over a wide range of power levels, with little or no redesign. Each RTG slice consists of a 250-watt heat source module, eight multicouple thermoelectric modules, and standard sections of insulator, housing, radiator fins, and electrical circuit. The design makes it possible to check each thermoelectric module for electrical performance, thermal contact, leaktightness, and performance stability, after the generator is fully assembled; and to replace any deficient modules without disassembling the generator or perturbing the others. The RTG end sections provide the spring-loaded supports required to hold the free-standing heat source stack together during launch vibration. Detailed analysis indicates that the present generation of RTGs, using the same heat source modules. There is a duplicate copy of this document. OSTI has a copy of this paper.

Power plants coordination for economic and environmental load dispatch of thermal power plants with wind generation systems  

Science Journals Connector (OSTI)

Economic load dispatch (ELD) and economic emission dispatch (EED) have been applied to obtain generation scheduling of thermal power plants at optimum fuel cost and emissions. Due to limited availability of quality coal, issue of environmental emissions and high prices of coal, installation of renewable energy systems are suggested in power grid. Renewable energy system preferably wind generators are used in co-working with thermal plant which reduces generation cost, coal requirement and environmental emissions. This paper presents Newton-Raphson method to obtain ELD and EED. System simulation and programming is carried out in MATLAB environment. Analysis has been made on generation cost and for nitrous oxides emissions only due to its harmful effects and its rising tendency with excess air. Price penalty factor is also calculated to determine emission cost. Doubly fed induction generator (DFIG) is suggested as wind energy systems in combination with coal-based thermal plant. Performance results related to generation scheduling, transmission line loading, bus voltages, total cost and environmental emissions are shown for coal-based thermal power plant and with co-generation. The investigation shows that with co-generation, coal-based thermal power plant runs at minimum emissions level which further reflects on the generation economy.

The aim of this researcher is to develop a complete wind central model driven doubly fed induction generator (DFIG) which feeds an AC power grid. For that, two-pulse width modulated (PWM) voltage converters are connected back to back between the rotor terminals of DFIG and the utility grid via a common DC link, in there, our contribution will appear in the utilisation of three levels voltage inverters in order to ameliorate the energy quality. The simulation was carried out on a 2 MW wind-turbine driven DFIG system and the developed unified model validity and the proposed control strategies feasibility are all confirmed by the simulated results.

Control strategies of doubly fed induction generator-based wind turbine system with new rotor current protection topology  

Science Journals Connector (OSTI)

A protection scheme of a doubly fed induction generator (DFIG) based wind turbine system during faults is crowbar activation. With this protection the rotor side converter (RSC) is temporarily disconnected and its vector control over the stator active and reactive power is lost leading to poor power quality at the point of common coupling (PCC). This paper presents a new protection scheme for transient rotor current to improve the performance of DFIG during grid disturbance. The new scheme consisting of a crowbar and series circuit is connected between the rotor windings and RSC to enhance the low voltage ride-through capability of DFIG. The proposed scheme successfully limits the transient rotor current and dc-link voltage and a disconnection of RSC from the rotor windings is avoided during fault. Additionally RSC and grid-side converter controllers are modified to improve the voltage at PCC. Simulations on matlab/Simulink verify the effectiveness of the proposed scheme.

Optimal site matching of wind turbine generator: Case study of the Gulf of Suez region in Egypt  

Science Journals Connector (OSTI)

During the last few years, Egypt has emerged as the leader of wind power in the Middle East and Africa. In the Gulf of Suez region, a continuously expanding large-scale grid-connected wind farm is available at Zafarana site. The Gulf of EL-Zayt site in the Gulf of Suez region is now under extensive studies related to wind power projects such as feasibility and bird migration studies. Therefore, the Gulf of Suez region is considered in this paper for optimal site matching of wind turbine generator (WTG). This paper treats the problem of site matching of WTG through improved formulation of the capacity factor. Such factor is estimated based on Weibull PDF and an accurate model for the WTG output-power-curve. Ornithological, martial, and other limitations placed on WTG hub heights in the Gulf of Suez region in Egypt are taken into account. In addition, a MATLAB based program is created to implement the presented technique of optimal site matching of WTG. Based on turbine-performance-index (TPI) maximization, optimal output-power-curve and optimal commercial WTG are determined for each candidate site in the Gulf of Suez region. Long-term performance measurements at Zafarana wind farms in comparison with the results are used to validate the presented technique and the optimality of the results.

Evaluation of wind energy potential and electricity generation at five locations in Jordan  

Science Journals Connector (OSTI)

Abstract Evaluation of the wind power from the knowledge of the mean monthly wind speeds of a typical year, and for five different locations in Jordan is analyzed and assessed. In addition, an investigation into the feasibility of using five different wind turbines of different rated power ranging from 100kW to 3000kW at each location to be employed in wind farms is examined. The data of the wind speeds over five years are fitted to the Weibull distribution, which is most frequently used and most appropriate, describing frequency distribution for wind moving over Jordan. The annual mean values of the wind speed and the frequency distributions were found for the five locations studied; Ras-Moneef, Azraq south; Safawi, Queen Alia Airport and Aqaba Airport. The locations included the eastern desert regions where wide plain lands are economically feasible to be used for wind farms. It is apparent from the results of the analysis that the highly promising sites of having good wind energy potential are Aqaba and Ras-Moneef, whereas, the desert sites of Safawi and Azraq South have only moderate potential and Queen Alia Airport have a lower potential. The annual mean values of the wind speed and power density of the observed and theoretical distributions are 5.5ms?1 and 160Wm?2 for Ras Moneef, 4.0ms?1 and 175Wm?2 for Azraq South, 4.5ms?1 and 94Wm?2 for Safawi, 3.13ms?1 and 31Wm?2 for Queen Alia Airport and 6.0ms?1 and 215Wm?2 for Aqaba Airport, respectively.

A KINETIC MODEL OF SOLAR WIND GENERATION BY OBLIQUE ION-CYCLOTRON WAVES  

SciTech Connect

The fast solar wind is generated by extended perpendicular ion heating in coronal holes, but the kinetic mechanism responsible for this heating has not been determined. One long-standing possibility is the resonant-cyclotron dissipation of ion-cyclotron waves, replenished from a turbulent cascade of interacting counter-propagating Alfven waves. We present results of a kinetic model for proton heating by the quasilinear resonant-cyclotron wave-particle interaction in a coronal hole. The resonant wave spectrum is taken as a power law in wavenumber, uniformly distributed in propagation direction between 0 deg. and 60 deg. with respect to the large-scale radial magnetic field. We obtain the steady-state solution of the kinetic guiding-center equation for the proton distribution in an expanding coronal hole, including the effects of large-scale forces of gravity, charge-separation electric field, Alfven wave ponderomotive force, and mirror force, along with the small-scale scattering from the wave dissipation. We find that plausible wave intensities can yield reasonable flow speeds and temperatures in the heliocentric radial range between 2 and 6 solar radii. We address the claim in earlier work that dissipation of parallel-propagating ion-cyclotron waves cannot provide enough acceleration and show that claim to be incorrect. We find that the combined action of the large-scale forces and the resonant-cyclotron scattering produces proton distribution functions with a characteristic structure: compressed in the sunward half of velocity space with a high-density shell separate from the origin, and relatively expanded in the anti-sunward half of velocity space. We suggest that qualitatively similar proton distributions would result from the kinetic evolution of any sufficiently effective perpendicular heating mechanism operating in an expanding coronal hole.

This paper recommend an optimal design model for designing hybrid solarwind systems employing battery banks for calculating the system optimum configurations and ensuring that the annualized cost of the systems is minimized while satisfying the custom required loss of power supply probability (LPSP). The five decision variables included in the optimization process are the PV module number, PV module slope angle, wind turbine number, wind turbine installation height and battery capacity. The proposed method has been applied to design a hybrid system to supply power for a telecommunication relay station along south-east coast of China. The research and project monitoring results of the hybrid project were reported, good complementary characteristics between the solar and wind energy were found, and the hybrid system turned out to be able to perform very well as expected throughout the year with the battery over-discharge situations seldom occurred.

Optimisation of voltage and frequency regulation in an isolated wind-driven six-phase self-excited induction generator  

Science Journals Connector (OSTI)

Abstract This paper presents a constant voltage operation of a Six-Phase Self-Excited Induction Generator (SPSEIG) driven by a fixed speed wind turbine using an Ant colony optimisation (ACO) technique to predict the behaviour of a the machine. In this paper, an attempt has been made to estimate the excitation capacitance requirements of a SPSEIG for maintaining rated terminal voltage and frequency. The range of capacitance variation required for maintaining constant terminal voltage while supplying a load of variable magnitude is evaluated. Analytical approaches, suitable for all the configurations of shunt capacitances such as variable excitation capacitance connected across (i) single three-phase winding set only and (ii) both the three-phase winding sets of an SPSEIG for operation as a simple shunt on no load and pure resistive load, are presented. The mathematical model developed is based on loop impedance method using graph theory. It is shown that the proposed technique is very effective and useful for making the SPSEIG feasible for remote areas with wind potential. The proposed approach is tested and compared with Genetic Algorithm (GA) and Fmincon technique.

Optimal sizing study of hybrid wind/PV/diesel power generation unit  

SciTech Connect

In this paper, a methodology of sizing optimization of a stand-alone hybrid wind/PV/diesel energy system is presented. This approach makes use of a deterministic algorithm to suggest, among a list of commercially available system devices, the optimal number and type of units ensuring that the total cost of the system is minimized while guaranteeing the availability of the energy. The collection of 6 months of data of wind speed, solar radiation and ambient temperature recorded for every hour of the day were used. The mathematical modeling of the main elements of the hybrid wind/PV/diesel system is exposed showing the more relevant sizing variables. A deterministic algorithm is used to minimize the total cost of the system while guaranteeing the satisfaction of the load demand. A comparison between the total cost of the hybrid wind/PV/diesel energy system with batteries and the hybrid wind/PV/diesel energy system without batteries is presented. The reached results demonstrate the practical utility of the used sizing methodology and show the influence of the battery storage on the total cost of the hybrid system. (author)

Statistical characterization of aggregated wind power from small clusters of generators  

Science Journals Connector (OSTI)

Abstract In this paper we address the problem of aggregating wind power. The purpose of the methodology presented here is to avoid the assumption of extreme values of correlation, meaning perfect dependence or perfect independence of the production. That is, we accept intermediate values of correlation, which we argue is of special interest for small-scale siting analysis, where the fluctuations of wind power production affect the capacity value or the size of energy storage. We provide a formulation that is based on the integration of the joint probability density function (PDF) of the wind power. We formulate this PDF by means of copula theory in order to cope with the involved representation of the marginal PDFs. As a result, we characterize the PDF of the aggregated wind power and the associated duration curve. We also present a simple formulation of the joint forced outage rate. These serves us for verifying, through a case analysis based on NREL datasets, that in some cases the assumption of extreme dependence in small-scale sites does not hold.

Ocean acoustic noise budgets: Application to the environmental assessment of offshore wind power generation.  

Science Journals Connector (OSTI)

A noise budget is a listing of the various sources of acoustic noise and their associated ranking by importance. A number of different types of budgets can be conceived using various acoustic measures such as intensity energy or duration of maximum amplitude level. These budgets are typically parameterized by frequency and are usually computed over 1/3 octave bands. As part of the environmental assessment of the proposed offshore wind powergeneration project under the Rhode Island Special Area Management Plan (SAMP) noise measurements were made using the Passive Acoustic Listener (PAL) systems off the coast of Rhode Island prior to the installation of any wind power facilities. Two PALs were deployed within two miles of Block Island in water depths of 20 m from October 6 to November 11 2008. The data included noise spectra and source identification every 3 min. Short snapshots of unusual sounds were also recorded. From this data the ocean acoustic noise budget is computed with contributions from shipping wind/waves marine mammals and rain from 500 Hz to 50 kHz. The shipnoise data is correlated with ship traffic data from the Automatic Identification System (AIS). [Funding provided by the Rhode Island Office of Energy Resources.

Simulation for Wind Turbine Generators -- With FAST and MATLAB-Simulink Modules  

SciTech Connect

This report presents the work done to develop generator and gearbox models in the Matrix Laboratory (MATLAB) environment and couple them to the National Renewable Energy Laboratory's Fatigue, Aerodynamics, Structures, and Turbulence (FAST) program. The goal of this project was to interface the superior aerodynamic and mechanical models of FAST to the excellent electrical generator models found in various Simulink libraries and applications. The scope was limited to Type 1, Type 2, and Type 3 generators and fairly basic gear-train models. Future work will include models of Type 4 generators and more-advanced gear-train models with increased degrees of freedom. As described in this study, implementation of the developed drivetrain model enables the software tool to be used in many ways. Several case studies are presented as examples of the many types of studies that can be performed using this tool.

Effects of variable renewable power on a country-scale electricity system: High penetration of hydro power plants and wind farms in electricity generation  

Science Journals Connector (OSTI)

The present article analyses the effects caused by variable power. The analysis concerns a country-scale electricity system with a relatively high penetration of seasonally variable hydro power plants and wind farms in the total electricity generation in 2030. For this purpose, the Latvian electricity system was chosen as an appropriate case study, as around half of its electricity is already generated from hydro power and numerous wind farm installations are planned for 2030. Results indicate that in such systems high renewable power variations occur between seasons causing a high probability of power deficit in the winter and power surplus in the spring. Based on the results, the wind farms' influence on the power deficit and surplus occurrences are discussed in detail. Wind farm generation decreases the probability of the electricity system being in power deficit, but increases the probability of the system being in power surplus. In the latter situation, the maximum value of power surplus increases since it is enhanced by the wind farm generation. Probability equations to express these changes are provided.

Novel fuzzy logic based sensorless maximum power point tracking strategy for wind turbine systems driven DFIG (doubly-fed induction generator)  

Science Journals Connector (OSTI)

Abstract This paper presents a novel FLC MPPT (fuzzy logic sensorless maximum power point tracking) method for WECS (wind energy conversion systems). The proposed method greatly reduces the speed variation range of the wind generator which leads to the downsizing the PWM (pulse width modulation) back-to-back converters by approximately 40% in comparison with conventional techniques. The method also increases the system's reliability by reducing the converter losses. Firstly, a MRAS (model reference adaptive system) based on fuzzy logic technique is used to estimate the DFIG (doubly-fed induction generator) rotor's speed. Then, a FLC MPPT (Fuzzy Logic Maximum Power Point Tracking) method is applied to provide the reference electromagnetic torque. Subsequently, in order to achieve the overall sensorless MPPT technique, the wind power is approximated from estimated generator speed and the reference of electromagnetic torque. Finally, the wind speed is estimated from the mechanical power using a fuzzy logic technique. The proposed control method has been applied to a WTG (wind turbine generator) driving a 3.7kW DFIG in variable speed mode. In order to validate the simulation results, experimental tests have been performed on a 3.7kW test bench, consisting of a DFIG and DC motor drive.

Impact of wind power on generation economy and emission from coal based thermal power plant  

Science Journals Connector (OSTI)

The major chunk of power generation is based on coal fueled thermal power plant. Due to increasing demand of power there will be future crises of coal reservoirs and its costing. Apart from this, coal based thermal power plant is the main source of environmental emissions like carbon dioxides (CO2), sulfur dioxides (SO2) and oxides of nitrogen (NOx) which not only degrades the air quality but also is responsible for global warming, acid rain etc. This paper proposes a combined working of Doubly Fed Induction Generator (DFIG) with coal based Synchronous Generator (SG) in the MATLAB environment. STATCOM is suggested at common coupling point to maintain voltage stability and also maintain the system in synchronism. Analysis have been made for environmental emissions, coal requirement and system economy for both the cases, when the total load supplied by only SG and with the combination. Emission analysis have been also made with the application of washed coal in SG. With the impact of DFIG energy generation from SG have been reduces which proportionally affects on coal requirement, generation cost and environmental emissions. Application of washed coal improves the performance of SG and also reduces the environmental emissions.

Solar wind energy transfer regions inside the dayside magnetopauseII. Evidence for an MHD generator process  

Science Journals Connector (OSTI)

In this paper a quantitative analysis of magnetosheath injection regions observed by PROGNOZ-7 in the dayside high latitude boundary layer is performed. Particular emphasis is laid on describing the consequences of the observed excess transverse momentum of solar wind ions (H+ and He2+) as compared to the magnetospheric ions (e.g. He+ and O+) in the magnetosheath injection regions, hereafter referred to as energy transfer regions. An important result of this study is that the observed excess drift velocity of the solar wind ions as compared to the magnetospheric ions can be interpreted as a negative inertia current being present in the boundary layer. This means that the inertia current goes against the local electric field and that particle kinetic energy is converted into electric energy there. The dayside high-latitude boundary layer therefore constitutes a voltage generator (at least with respect to the injected magnetosheath plasma). The MHD-theory predicts a strong coupling of the energy transfer process in the boundary layer and the ionosphere, both regions being connected by field aligned currents. The rate of decay of the inertia current in the injected plasma element is in the range of a few minutes, a value which is directly proportional to the ionospheric resistance. By taking into account both the Hall and the Pedersen conductivities in the ionosphere, the theory also predicts a strong coupling between ionospheric East/West and North/South currents. A considerable part of the inertia current may actually flow in the tangential (East/West) direction due to this coupling. Thus, a consequence of the boundary layer energy transfer process is that it may generate currents, powering other magnetospheric plasma processes, down to ionospheric heights.

Darrieus vertical axis wind turbine for power generation I: Assessment of Darrieus VAWT configurations  

Science Journals Connector (OSTI)

Abstract This paper aims to assess the Darrieus vertical axis wind turbine (VAWT) configurations, including the drawbacks of each variation that hindered the development into large scale rotor. A comprehensive timeline is given as a lineage chart. The variations are assessed on the performance, components and operational reliability. In addition, current development and future prospects of Darrieus VAWT are presented. The Darrieus VAWT patented in France in 1925 and in the US in 1931 had two configurations: (i) curved blades and (ii) straight blades configurations. Curved blades configuration (egg-beater or phi-rotor) has evolved from the conventional guy-wires support into fixed-on-tower and cantilevered versions. Straight blades configuration used to have variable-geometry (Musgrove-rotor), variable-pitch (Giromill), Diamond, Delta and V/Y rotor variations. They were stopped due to low economical value, i.e. high specific cost of energy (COE). Musgrove-rotor has evolved into fixed-pitch straight-bladed H-rotor (referred as H-rotor in this paper for simplicity). H-rotor, in turn, has evolved into several variations: Articulating, Tilted and Helical H-rotors.

Employing two novel mechanical fault ride through controllers for keeping stability of fixed speed wind generation systems hosted by standalone micro-grid  

Science Journals Connector (OSTI)

Abstract This paper proposes and designs two novels Fault Ride Through (FRT) controllers for maintaining Fixed Speed Wind Generation system (FSWGs) stability during fault events. The first technique has been implemented by increasing the wind turbine blade pitch angle with maximum possible rate to reduce the mechanical extracted wind power and consequently suppress wind generation system acceleration. The second FRT technique has been verified by adapting gear ratio of wind generation system to run far from optimum maximum power point and help FRT process. Effectiveness of the two proposed FRT techniques has been proven by accurate simulation of the most severe disturbance conditions. Also, Results indicated that second technique gives faster response than the first one. Without employing any FRT technique, \\{FSWGs\\} cannot keep its stability and the standalone Micro-Grid (MG) transfers to the blackout mode. Implementation the two FRT techniques requires no additional hardware. Only, control algorithms need little modification to deal with fault event and help FRT process. This fact makes the two proposed FRT techniques are simple, practical and highly economical attractive.

A Gravitational Search Algorithm (GSA) based Photo-Voltaic (PV) excitation control strategy for single phase operation of three phase wind-turbine coupled induction generator  

Science Journals Connector (OSTI)

Abstract Three phase induction generators are widely used for single phase operation in wind based micro-generation schemes to cater single phase loads due to various advantages. This paper presents an improved control methodology for self excited three phase induction generator operating in single phase mode. The excitation is controlled through an inverter with Photo-Voltaic (PV) panels providing power to the dc bus. The proposed technique enables the generator for building up voltage from low wind speeds compared to conventional three phase machines. A capacitor connected across load terminals reduces the reactive power supplied by the inverter connected across the other two phases. Gravitational search algorithm (GSA) is used to calculate the switching angles of the inverter under various load and wind speeds for minimum Total Harmonic Distortion (THD) of the generated voltage. The proposed induction generator is aimed to be conveniently used in remote and grid isolated areas as a portable source of electrical power driving single phase loads. Simulations and experiments performed on a 3-phase 1kW, 415V, 50Hz, 1440r/min induction machine validates the proposed concept.

User`s guide for PLTWIND Version 1.0: PC-based software for generating plots of monitored wind data and gridded wind fields for Hanford emergency response applications  

SciTech Connect

This document is a user`s guide for the PLoT Near-Surface WIND (PLTWIND) modeling system. PLTWIND is a personal-computer-based software product designed to produce graphical displays of Hanford wind observations and model-generated wind fields. The real-time wind data processed by PLTWIND are acquired from the mainframe computer system at the Hanford Meteorology Station and copied to PLTWIND systems by the Hanford Local Area Network (HLAN). PLTWIND is designed fbr operation on an IBM-compatible PC with a connection to the HLAN. An HP-compatible pen plotter or laser printer (with a minimum of 1.5 megabytes of memory and a Plotter-in-a-Cartridge hardware) is required to generate hardcopies of PLTWTND`s graphical products. PLTWM`s products are intended for use by emergency response personnel in evaluating atmospheric dispersion characteristics in the near-surface environment. Model products provide important atmospheric information to hazard evaluators; however, these products are only tools for assessing near-surface atmospheric transport and should not be interrupted as providing definitive representation of atmospheric conditions.

Wind energy conversion system  

DOE Patents (OSTI)

The wind energy conversion system includes a wind machine having a propeller connected to a generator of electric power, the propeller rotating the generator in response to force of an incident wind. The generator converts the power of the wind to electric power for use by an electric load. Circuitry for varying the duty factor of the generator output power is connected between the generator and the load to thereby alter a loading of the generator and the propeller by the electric load. Wind speed is sensed electro-optically to provide data of wind speed upwind of the propeller, to thereby permit tip speed ratio circuitry to operate the power control circuitry and thereby optimize the tip speed ratio by varying the loading of the propeller. Accordingly, the efficiency of the wind energy conversion system is maximized.

Modeling, analysis and comparison of TSR and OTC methods for MPPT and power smoothing in permanent magnet synchronous generator-based wind turbines  

Science Journals Connector (OSTI)

Abstract This paper presents a small signal modeling of a direct-driven permanent magnet synchronous generator (PMSG) based on wind turbine which is connected to the grid via back-to-back converters. The proposed small signal model includes two maximum power point tracking (MPPT) controllers: tip speed ratio (TSR) control and optimal torque control (OTC). These methods are analytically compared to illustrate MPPT and power smoothing capability. Then, to compare the MPPT and power smoothing operation of the mentioned methods, simulations are performed in MATLAB/Simulink software. From the simulation results, OTC is highly efficient in power smoothing enhancement and has clearly good performance to extract maximum power from wind; however, TSR control has definitely fast responses to wind speed variations with the expense of higher fluctuations due to its non-minimum phase characteristic.

Wind Power Wind Power Jump to: navigation, search Wind Power WIndfarm.Sunset.jpg Wind power is a form of solar energy.[1] Wind is caused by the uneven heating of the atmosphere by the sun, variations in the earth's surface, and rotation of the earth. Mountains, bodies of water, and vegetation all influence wind flow patterns[2], [3]. Wind energy (or wind power) describes the process by which wind is used to generate electricity. Wind turbines convert the energy in wind to electricity by rotating propeller-like blades around a rotor.

Plug-in hybrid electric vehicles as a way to maximize the integration of variable renewable energy in power systems: The case of wind generation in northeastern Brazil  

Science Journals Connector (OSTI)

Several studies have proposed different tools for analyzing the integration of variable renewable energy into power grids. This study applies an optimization tool to model the expansion of the electric power system in northeastern Brazil, enabling the most efficient dispatch of the variable output of the wind farms that will be built in the region over the next 20 years. The expected combined expansion of wind generation with conventional inflexible generation facilities, such as nuclear plants and run-of-the-river hydropower plants, poses risks of future mismatch between supply and demand in northeastern Brazil. Therefore, this article evaluates the possibility of using a fleet of plug-in hybrid electric vehicles (PHEVs) to regularize possible energy imbalances. Findings indicate that a dedicated fleet of 500 thousand \\{PHEVs\\} in 2015, and a further 1.5 million in 2030, could be recharged overnight to take advantage of the surplus power generated by wind farms. To avoid the initial costs of smart grids, this article suggests, as a first step, the use of a governmental PHEV fleet that allows fleet managers to control battery charging times. Finally, the study demonstrates the advantages of optimizing simultaneously the power and transport sectors to test the strategy suggested here.

Wind energy  

Science Journals Connector (OSTI)

Wind energy is rapidly growing. In 2006 the installed generating capacity in the world increased by 25%, a growth rate which has more or less been sustained during the last decade. And there is no reason to believe that this growth will slow significantly in the coming years. For example, the United Kingdom's goal for installed wind turbines by 2020 is 33GW up from 2GW in 2006, an average annual growth rate of 22% over that period. More than half of all turbines are installed in Europe, but United States, India and lately China are also rapidly growing markets. The cradle of modern wind energy was set by innovative blacksmiths in rural Denmark. Now the wind provides more than 20% of the electrical power in Denmark, the industry has professionalized and has close ties with public research at universities. This focus issue is concerned with research in wind energy. The main purposes of research in wind energy are to: decrease the cost of power generated by the wind; increase the reliability and predictability of the energy source; investigate and reduce the adverse environmental impact of massive deployment of wind turbines; build research based educations for wind energy engineers. This focus issue contains contributions from several fields of research. Decreased costs cover a very wide range of activities from aerodynamics of the wind turbine blades, optimal site selection for the turbines, optimization of the electrical grid and power market for a fluctuating source, more efficient electrical generators and gears, and new materials and production techniques for turbine manufacturing. The United Kingdom recently started the construction of the London Array, a 1GW off-shore wind farm east of London consisting of several hundred turbines. To design such a farm optimally it is necessary to understand the chaotic and very turbulent flow downwind from a turbine, which decreases the power production and increases the mechanical loads on other nearby turbines. Also addressed within the issue is how much conventional power production can be replaced by the ceaseless wind, with the question of how Greece's target of 29% renewables by 2020 is to be met efficiently. Other topics include an innovative way to determine the power curve of a turbine experimentally more accurately, the use of fluid dynamics tools to investigate the implications of placing vortex generators on wind turbine blades (thereby possibly improving their efficiency) and a study of the perception of wind turbine noise. It turns out that a small but significant fraction of wind turbine neighbours feel that turbine generated noise impairs their ability to rest. The annoyance is correlated with a negative attitude towards the visual impact on the landscape, but what is cause and effect is too early to say. As mentioned there is a rush for wind turbines in many countries. However, this positive development for the global climate is currently limited by practical barriers. One bottleneck is the difficulties for the sub-suppliers of gears and other parts to meet the demand. Another is the difficulties to meet the demand for engineers specialized in wind. For that reason the Technical University of Denmark (DTU) recently launched the world's first Wind Energy Masters Program. Here and elsewhere in the world of wind education and research we should really speed up now, as our chances of contributing to emission free energy production and a healthier global climate have never been better.

Environmental assessment of offshore wind power generation near Rhode Island: Acoustic and electromagnetic effects on marine animals.  

Science Journals Connector (OSTI)

An offshore wind farm is planned for Rhode Island coastal waters. The developer has proposed to deploy wind turbines in two stages: 5 turbines in shallow waters 5 km south of Block Island and 100 turbines in deeper waters 30 km to the east. As part of the planning of the proposed offshore wind powergeneration project under the Rhode Island Special Area Management Plan ambient acoustic and electromagneticmeasurements were made in the area. Two passive acoustic listener (PAL) systems were deployed within 4 km of Block Island from October 6 to November 11 2008. Data from the PALs were used to compute the ocean acousticnoise budget and other statistics by source. Transmission loss measurements were also made to support the noise budget calculation. Measurements of airborne noise from a 1.5?MW land?based wind turbine already in operation in Rhode Island were made. To support the electromagneticeffect study an underwater magnetometer was towed at the two proposed sites and over an operational underwater 23?kV power cable. A preliminary assessment of the effects of the offshore wind farm on marine animals at these sites will be presented. [Funding provided by the RI Office of Energy Resources.

New England Wind Forum: Selling Wind Power  

Wind Powering America (EERE)

Selling Wind Power Selling Wind Power Markets are either well-developed or developing for each of the 'products' produced by wind generators. These include electricity products and generation attributes. Electricity Electricity can be used in two ways: on-site (interconnected behind a retail customer's meter) of for sales of electricity over the electric grid. On-site generation can displace a portion of a customer's purchases of electricity from the grid. In addition, net metering rules are in place at the state level that in some cases allow generation in excess of on-site load to be sold back to the local utility (see state pages for net metering specifics). For sales over the electricity grid, the Independent System Operator of New England (ISO New England) creates and manages a wholesale market for electric energy, capacity, and ancillary services within the New England Power Pool (NEPOOL). Wind generators may sell their electric energy and capacity in spot markets organized by the ISO, or they may contract with wholesale buyers to sell these products for any term to buyers operating in the ISO New England marketplace. Wind generators do not generally produce other marketable ancillary services. The ISO has rules specific to the operation of wind generators reflecting operations, scheduling, calculation of installed capacity credit, and so forth.

NREL: Learning - Wind Energy Basics: How Wind Turbines Work  

NLE Websites -- All DOE Office Websites (Extended Search)

Wind Energy Basics: How Wind Turbines Work Wind Energy Basics: How Wind Turbines Work We have been harnessing the wind's energy for hundreds of years. From old Holland to farms in the United States, windmills have been used for pumping water or grinding grain. Today, the windmill's modern equivalent-a wind turbine-can use the wind's energy to generate electricity. Wind turbines, like windmills, are mounted on a tower to capture the most energy. At 100 feet (30 meters) or more aboveground, they can take advantage of the faster and less turbulent wind. Turbines catch the wind's energy with their propeller-like blades. Usually, two or three blades are mounted on a shaft to form a rotor. A blade acts much like an airplane wing. When the wind blows, a pocket of low-pressure air forms on the downwind side of the blade. The low-pressure

Energy from the wind  

Science Journals Connector (OSTI)

The large?scale generation of electrical power by wind turbine fields is discussed. It is shown that the maximum power which can be extracted by a wind turbine is 16/27 or 59.3% of the power available in the wind. An estimate is made of the total electrical power which could be generated in the United States by utilizing wind energy. The material in this paper was presented by the authors in a one?semester course on energy science. It could also be used in an introductory physics class as an illustration of elementary fluid mechanics concepts and of the basic principles of energy and momentum conservation.

This wind energy resource atlas identifies the wind characteristics and distribution of the wind resource in the country of Armenia. The detailed wind resource maps and other information contained in the atlas facilitate the identification of prospective areas for use of wind energy technologies for utility-scale power generation and off-grid wind energy applications. The maps portray the wind resource with high-resolution (1-km2) grids of wind power density at 50-m above ground. The wind maps were created at the National Renewable Energy Laboratory (NREL) using a computerized wind mapping system that uses Geographic Information System (GIS) software.

Environmental impact of wind energy  

Science Journals Connector (OSTI)

One purpose of wind turbines is to provide pollution-free electric power at a reasonable price in an environmentally sound way. In this focus issue the latest research on the environmental impact of wind farms is presented. Offshore wind farms affect the marine fauna in both positive and negative ways. For example, some farms are safe havens for porpoises while other farms show fewer harbor porpoises even after ten years. Atmospheric computer experiments are carried out to investigate the possible impact and resource of future massive installations of wind turbines. The following questions are treated. What is the global capacity for energy production by the wind? Will the added turbulence and reduced wind speeds generated by massive wind farms cool or heat the surface? Can wind farms affect precipitation? It is also shown through life-cycle analysis how wind energy can reduce the atmospheric emission of eight air pollutants. Finally, noise generation and its impact on humans are studied.

On the Heating of the Solar Corona and the Acceleration of the Low-Speed Solar Wind by Acoustic Waves Generated in Corona  

E-Print Network (OSTI)

We investigate possibilities of solar coronal heating by acoustic waves generated not at the photosphere but in the corona, aiming at heating in the mid- to low-latitude corona where the low-speed wind is expected to come from. Acoustic waves of period tau ~ 100s are triggered by chromospheric reconnection, one model of small scale magnetic reconnection events recently proposed by Sturrock. These waves having a finite amplitude eventually form shocks to shape sawtooth waves (N-waves), and directly heat the surrounding corona by dissipation of their wave energy. Outward propagation of the N-waves is treated based on the weak shock theory, so that the heating rate can be evaluated consistently with physical properties of the background coronal plasma without setting a dissipation length in an ad hoc manner. We construct coronal structures from the upper chromosphere to the outside of 1AU for various inputs of the acoustic waves having a range of energy flux of F_{w,0} = (1-20) times 10^5 erg cm^{-2} s^{-1} and a period of tau = 60-300s. The heating by the N-wave dissipation effectively works in the inner corona and we find that the waves of F_{w,0} >= 2 times 10^5 erg cm^{-2} s^{-1} and tau >= 60s could maintain peak coronal temperature, T_{max} > 10^6 K. The model could also reproduce the density profile observed in the streamer region. However, due to its short dissipation length, the location of T_{max} is closer to the surface than the observation, and the resultant flow velocity of the solar wind is lower than the observed profile of the low-speed wind. The cooperations with other heating and acceleration sources with the larger dissipation length are inevitable to reproduce the real solar corona.

Magnetism, rotation and accretion in Herbig Ae-Be stars  

E-Print Network (OSTI)

Studies of stellar magnetism at the pre-main sequence phase can provide important new insights into the detailed physics of the late stages of star formation, and into the observed properties of main sequence stars. This is especially true at intermediate stellar masses, where magnetic fields are strong and globally organised, and therefore most amenable to direct study. This talk reviews recent high-precision ESPaDOnS observations of pre-main sequence Herbig Ae-Be stars, which are yielding qualitatively new information about intermediate-mass stars: the origin and evolution of their magnetic fields, the role of magnetic fields in generating their spectroscopic activity and in mediating accretion in their late formative stages, and the factors influencing their rotational angular momentum.

Investigation of Small Wind-Turbine Induction Generators : Final Technical Report, September 16, 1980-December 31, 1982.  

SciTech Connect

A new and accurate experimental set-up was developed to test induction machines in the 1-5 kW range. Two single-phase induction generators were tested - the Enertech 1500 and Enertech 1800. A detailed mathematical model to evaluate the performance of single-phase induction generators was developed and documented in the form of a FORTRAN computer simulation program. Then the program was used to analyze the Enertech 1800 and the results were compared with the test results. (LEW)

Case study evaluating the potential for small wind energy conversion systems (SWECS) as an integral part of the generating mix of a regional utility. Final report, ICFAR Project 05-3-7001-0  

SciTech Connect

Average annual measured wind speeds in Indiana extrapolated to 30m vary from approximately 4.5 to 6.5 m/s. Stronger winds are observed in the northern part of the state than in the southern, with the central region exhibiting intermediate values. The annual array capacity factors of the three selected wind turbines operating in an Indianapolis wind regime at height 30m varied from 0.243 for the machine with rated power density (P/sub rd/) 244 W/m/sup 2/ to 0.462 for the machine with P/sub rd/ = 93 W/m/sup 2/ - a difference in power output of nearly a factor of 2. These results strongly suggest that wind turbines with low rated power densities are best suited for Indiana's wind regimes. The economic analyses of WECS break-even costs show that, given the assumptions of the analysis, a wind turbine with P/sub rd/ = 244 W/m/sup 2/ would be economically competitive with conventional generating sources were the capital cost not to exceed about $750 per rated kW (1989 dollars). This figure for a machine with P/sub rd/ = 93 W/m/sup 2/ is nearly $2000/kW. Brought back to 1980 dollars by an inflation factor of (1.08)/sup 9/ = 2.00, these values reckon to $375/kW and $1000/kW, respectively.

Vertical axis wind turbines  

DOE Patents (OSTI)

A vertical axis wind turbine is described. The wind turbine can include a top ring, a middle ring and a lower ring, wherein a plurality of vertical airfoils are disposed between the rings. For example, three vertical airfoils can be attached between the upper ring and the middle ring. In addition, three more vertical airfoils can be attached between the lower ring and the middle ring. When wind contacts the vertically arranged airfoils the rings begin to spin. By connecting the rings to a center pole which spins an alternator, electricity can be generated from wind.

Comparative life cycle energy, emission, and economic analysis of 100kW nameplate wind power generation  

Science Journals Connector (OSTI)

This study compares three configurations of wind turbines to produce a nameplate power of 100kW applying LCA methodology over a lifetime of 25 years. Alternatives under study are: installing twenty Endurance (EN) 5kW, or five Jacobs (JA) 20kW, or one Northern Power (NP) 100kW turbines in the Halkirk region of Alberta, Canada. The comparison has been done taking life cycle energy, environment and economic aspects into consideration. Each parameter has been quantified corresponding to a functional unit (FU) of 1kWh. Life cycle energy requirement for NP is found to be 133.3kJ/kWh, which is about 69% and 41% less than EN and JA respectively. Global warming impact from NP is found to be 17.8gCO2eq/kWh, which is around 58% and 29% less respective to EN and JA. The acidification (SO2eq/kWh) and ground level ozone [(VOC+NOx)/kWh] impacts from NP are also found significantly less compared to EN and JA configuration. The difference in relative environmental impacts from configurations is found to be less while performing uncertainty analysis, but does not alter the ranking of configurations. At 10% internal rate of return (IRR), electricity price for NP is 0.21$/kWh, whereas EN and JA prices are 65% and 16% higher respectively.

Measurement of the underwater noise levels generated from marine piling associated with the installation of offshore wind turbines.  

Science Journals Connector (OSTI)

Marine piling is the most commonly used method for the installation of offshore wind turbines in the shallow coastal waters in the UK and consists of steel mono?piles being driven into the seabed using powerful hydraulic hammers. This is a source of impulsive sound of potentially high level that can travel a considerable distance in the water column and has the potential for impact on marine life. This presentation describes methodologies developed for measurement of marine piling and for the estimation of the energy source level. Measurements are presented for piles of typically 5 m in diameter driven by hammers with typical strike energies of 1000 kJ. Data were recorded as a function of range from the source using vessel?deployed hydrophones and using fixed acoustic buoys that recorded the entire piling sequence including soft start. The methodology of measurement is described along with the method of estimation of the energy source level. Limitations and knowledge gaps are discussed.

Federal and state policies play an important role in encouraging wind energy development by leveling the playing field compared to other energy sources. Many of the substantial benefits of wind power as a domestic, zero-emission part of the energy portfolio - sustainability, displacement of pollutant emissions from other power sources, fuel diversity, price stabilization, keeping a substantial portion of energy expenditures in the local economy - are shared by society as a whole and cannot be readily captured by wind generators directly in the price they charge for their output. In addition, while wind power receives some policy support, the level of federal incentives for wind represents less than 1% of the subsidies and tax breaks given to the fossil fuels and nuclear industries (source: "Wind Power An Increasingly Competitive Source of New Generation." Wind Energy Weekly #1130.).

Operating Reserve Reductions from a Proposed Energy Imbalance Market with Wind and Solar Generation in the Western Interconnection  

SciTech Connect

This paper considers several alternative forms of an energy imbalance market (EIM) proposed in the nonmarket areas of the Western Interconnection. The proposed EIM includes two changes in operating practices that independently reduce variability and increase access to responsive resources: balancing authority cooperation and sub-hourly dispatch. As the penetration of variable generation increases on the power system, additional interest in coordination would likely occur. Several alternative approaches could be used, but consideration of any form of coordinated unit commitment is beyond the scope of this analysis. This report examines the benefits of several possible EIM implementations--both separately and in concert.

Distributed Wind Energy in Idaho  

SciTech Connect

Project Objective: This project is a research and development program aimed at furthering distributed wind technology. In particular, this project addresses some of the barriers to distributed wind energy utilization in Idaho. Background: At its core, the technological challenge inherent in Wind Energy is the transformation of a highly variable form of energy to one which is compatible with the commercial power grid or another useful application. A major economic barrier to the success of distributed wind technology is the relatively high capital investment (and related long payback periods) associated with wind turbines. This project will carry out fundamental research and technology development to address both the technological and economic barriers. â?¢ Active drive train control holds the potential to improve the overall efficiency of a turbine system by allowing variable speed turbine operation while ensuring a tight control of generator shaft speed, thus greatly simplifying power conditioning. â?¢ Recent blade aerodynamic advancements have been focused on large, utility-scale wind turbine generators (WTGs) as opposed to smaller WTGs designed for distributed generation. Because of Reynolds Number considerations, blade designs do not scale well. Blades which are aerodynamically optimized for distributed-scale WTGs can potentially reduce the cost of electricity by increasing shaft-torque in a given wind speed. â?¢ Grid-connected electric generators typically operate at a fixed speed. If a generator were able to economically operate at multiple speeds, it could potentially convert more of the windâ??s energy to electricity, thus reducing the cost of electricity. This research directly supports the stated goal of the Wind and Hydropower Technologies Program for Distributed Wind Energy Technology: By 2007, reduce the cost of electricity from distributed wind systems to 10 to 15 cents/kWh in Class 3 wind resources, the same level that is currently achievable in Class 5 winds.

Airborne Wind Turbine  

SciTech Connect

Broad Funding Opportunity Announcement Project: Makani Power is developing an Airborne Wind Turbine (AWT) that eliminates 90% of the mass of a conventional wind turbine and accesses a stronger, more consistent wind at altitudes of near 1,000 feet. At these altitudes, 85% of the country can offer viable wind resources compared to only 15% accessible with current technology. Additionally, the Makani Power wing can be economically deployed in deep offshore waters, opening up a resource which is 4 times greater than the entire U.S. electrical generation capacity. Makani Power has demonstrated the core technology, including autonomous launch, land, and power generation with an 8 meter wingspan, 20 kW prototype. At commercial scale, Makani Power aims to develop a 600 kW, 28 meter wingspan product capable of delivering energy at an unsubsidized cost competitive with coal, the current benchmark for low-cost power.

Wind Speed Data Analysis using Wavelet Transform  

E-Print Network (OSTI)

AbstractRenewable energy systems are becoming a topic of great interest and investment in the world. In recent years wind power generation has experienced a very fast development in the whole world. For planning and successful implementations of good wind power plant projects, wind potential measurements are required. In these projects, of great importance is the effective choice of the micro location for wind potential measurements, installation of the measurement station with the appropriate measuring equipment, its maintenance and analysis of the gained data on wind potential characteristics. In this paper, a wavelet transform has been applied to analyze the wind speed data in the context of insight in the characteristics of the wind and the selection of suitable locations that could be the subject of a wind farm construction. This approach shows that it can be a useful tool in investigation of wind potential. KeywordsWind potential, Wind speed data, Wavelet transform.

Magnetism of Herbig Ae/Be stars  

E-Print Network (OSTI)

Observations of magnetic fields of stars at the pre-main sequence phase can provide important new insights into the complex physics of the late stages of star formation. This is especially true at intermediate stellar masses, where magnetic fields are strong and globally organised, and therefore most amenable to direct study. Recent circularly-polarised spectroscopic observations of pre-main sequence Herbig Ae/Be stars have revealed the presence of organised magnetic fields in the photospheres of a small fraction of these objects. To date, 9 magnetic HAeBe stars have been detected, and those detections confirmed by repeated observations. The morphology and variability of their Stokes V signatures indicates that their magnetic fields have important dipole components of kG strength, and that the dipole is stable on timescales ofat least years. These magnetic stars exhibit a large range of stellar mass, from about 2-13 solar masses, and diverse rotational properties, with vsini from a few km/s to 200 km/s. Most ...

New England Wind Forum: Technical Challenges  

Wind Powering America (EERE)

Technical Challenges Technical Challenges Wind power is by its nature variable, and as a result, it differs from the majority of generation supplying the electric grid. Aspects of this variability are often cited as shortcomings. For instance, the fact that wind power will not be as regularly and reliably available at system peak times as most other generators is sometimes used to argue that wind power requires additional backup resources by other generation on a one-to-one basis. And wind's relatively low capacity factor (a ratio of the total energy output relative to the theoretical sustained peak output) is sometimes used to characterize wind generators as inefficient. It's been stated that other generation will have to be operated in such an inefficient manner to react to wind that it will not reduce fossil fuel usage or emissions. Here we address concerns that wind power's variability will eradicate any expected benefit.
