Design of isolated renewable hybrid power systems  

SciTech Connect (OSTI)

Isolated electrical power generating units can be used as an economically viable alternative to electrify remote villages where grid extension is not feasible. One of the options for building isolated power systems is by hybridizing renewable power sources like wind, solar, micro-hydro, etc. along with appropriate energy storage. A method to optimally size and to evaluate the cost of energy produced by a renewable hybrid system is proposed in this paper. The proposed method, which is based on the design space approach, can be used to determine the conditions for which hybridization of the system is cost effective. The simple and novel methodology, proposed in this paper, is based on the principles of process integration. It finds the minimum battery capacity when the availability and ratings of various renewable resources as well as load demand are known. The battery sizing methodology is used to determine the sizing curve and thereby the feasible design space for the entire system. Chance constrained programming approach is used to account for the stochastic nature of the renewable energy resources and to arrive at the design space. The optimal system configuration in the entire design space is selected based on the lowest cost of energy, subject to a specified reliability criterion. The effects of variation of the specified system reliability and the coefficient of correlation between renewable sources on the design space, as well as the optimum configuration are also studied in this paper. The proposed method is demonstrated by designing an isolated power system for an Indian village utilizing wind-solar photovoltaic-battery system. (author)

Broader source: All U.S. Department of Energy (DOE) Office Webpages (Extended Search)

On-site Renewable Energy Systems On-site Renewable Energy Systems For consumers or organizations wishing to install on-site renewable energy systems, there are a variety of options available, including electricity generating systems and thermal systems that can displace electricity or fossil fuel use. Solar photovoltaics convert sunlight directly into electricity. Solar hot water systems use the sun's energy to heat water. Wind turbines convert the kinetic energy in wind into mechanical power that runs a generator to produce electricity. Geothermal heat pumps use the constant temperature of the upper 10 feet of the Earth to heat and cool buildings. Fuel cells produce electricity from hydrogen and oxygen and can be powered by a number of sources, including renewables. Biomass power systems use biomass feedstocks such as wood waste or methane from animal waste or other sources to generate electricity. Biomass resources can also be used in direct heat and combined heat and power applications.

The RenewElec Project: Variable Renewable Energy and the Power System  

SciTech Connect (OSTI)

Variable energy resources, such as wind power, now produce about 4% of U.S. electricity. They can play a significantly expanded role if the U.S. adopts a systems approach that considers affordability, security and reliability. Reaching a 20-30% renewable portfolio standard goal is possible, but not without changes in the management and regulation of the power system, including accurately assessing and preparing for the operational effects of renewable generation. The RenewElec project will help the nation make the transition to the use of significant amounts of electric generation from variable and intermittent sources of renewable power.

Multiobjective Optimization of Renewable Energy Penetration Rate in Power Systems  

Science Journals Connector (OSTI)

Abstract Nowadays, multi-source systems based on renewable energy technologies become the key to a sustainable energy supply infrastructure against the rising cost and the pollutant nature of fossil primary energy used in conventional power plant. However, the cost of renewable energy technologies and the reliability of a multi-sources generation system are generally conflicting with each other. This paper presents a multiobjective formulation to allow optimizing simultaneously both the annualized renewable energy cost the system reliability defined as the renewable energy - load disparity (RELD). This later takes into account the lack of energy as well as the exceed weighted by a penalty factor. The optimization is reach by acting on the penetration rate of each type of renewable generation technologies in order to satisfy a certain load curve. In order to solve this problem, this work suggests to use the fast and elitist multiobjective genetic algorithm: NSGA-II. A case study shows that the use of diversified resources allows to handle the RELD and to decrease the exceed renewable energy (RERE) and load energy notsupplied (LENS).

Power System Study for Renewable Energy Interconnection in Malaysia  

Science Journals Connector (OSTI)

The renewable energy (RE) sector has grown exponentially in Malaysia with the introduction of the Feed-In-Tariff (FIT) by the Ministry of Energy, Green Technology and Water. Photovoltaic, biogas, biomass and mini hydro are among the renewable energy sources which offer a lucrative tariff to incite developers in taking the green technology route. In order to receive the FIT, a developer is required by the utility company to perform a power system analysis which will determine the technical feasibility of an RE interconnection to the utility company's existing grid system. There are a number of aspects which the analysis looks at, the most important being the load flow and fault levels in the network after the introduction of an RE source. The analysis is done by modelling the utility company's existing network and simulating the network with the interconnection of an RE source. The results are then compared to the values before an interconnection is made as well as ensuring the voltage rise or the increase in fault levels do not violate any pre-existing regulations set by the utility company. This paper will delve into the mechanics of performing a load flow analysis and examining the results obtained.

A review on promoting share of renewable energy by green-trading mechanisms in power system  

Science Journals Connector (OSTI)

Abstract In order to promote the development of renewable energy power generation, many countries have issued corresponding policies. Meanwhile, some green-trading mechanisms have been implemented in power industry. And this paper has mainly presented a review on promoting share of renewable energy by green-trading mechanisms in power system with a focus on promotion effects of three mechanisms: feed-in tariff, renewable portfolio standard and emission trading scheme. Apart from a review, summaries, comparisons, and an outlook for future study are also presented. Our review suggests that feed-in tariff and renewable portfolio standard can effectively increase the share of renewable energy power and lead to renewable resource diversity. In addition, emission trading also provides stimulus for development of renewable energy besides mitigation of carbon emission.

Design of Micro-grid System Based on Renewable Power Generation Units  

E-Print Network [OSTI]

Abstract- Micro-grid system is currently a conceptual solution to fulfill the commitment of reliable power delivery for future power systems. Renewable power sources such as wind and hydro offer the best potential for emission free power for future micro-grid systems. This paper presents a micro-grid system based on wind and hydro power sources and addresses issues related to operation, control, and stability of the system. The micro-grid system investigated in this paper represents a case study in Newfoundland, Canada. It consists of a small hydro generation unit and a wind farm that contains nine variable- speed, double-fed induction generator based wind turbines. Using Matlab/Simulink, the system is modeled and simulated to identify the technical issues involved in the operation of a micro-grid system based on renewable power generation units. The operational modes, technical challenges and a brief outline of conceptual approaches to addressing some of the technical issues are presented for further investigation.

Multi-criteria Operation Strategies of Power-to-Heat-Systems in Virtual Power Plants with a High Penetration of Renewable Energies  

Science Journals Connector (OSTI)

Abstract The integration of renewable energy into the existing energy supply system is a core challenge regarding the successful realization of the German Energiewende. One concept to integrate decentralized regenerative power generators is a virtual power plant that operates many small facilities as one power plant. Essential parts of the concept are controllable loads and generators to reduce the impact of volatile energy resource like wind power stations on operational planning. Power-to-Heat-Systems (P2H) are one possible technology that can be used to a limited extent as a controllable load. The P2H-system as a component of virtual power plants is capable of supplying flexibility due to various possible operation strategies. This flexibility can either be used for ancillary services (primary, secondary and tertiary ancillary services), to provide schedule energy or for balancing group management. This paper presents a modeling approach for P2H systems as a component of virtual power plants with a high share of renewable energies. The operation strategies are evaluated with respect to economic and technical aspects and uncertainties in generation and load. The operation strategies of P2H systems are shown with regard to market integration of renewable energies within a virtual power plant and the provision of ancillary services.

Renewable Energy for Sustainable Rural Village Power  

SciTech Connect (OSTI)

It is estimated that two billion people live without electricity and its services worldwide. In addition, there is a sizeable number of rural villages that have limited electrical service, with either part-day operation by diesel generator or partial electrification. For many villages connected to the grid, power is often sporadically available and of poor quality. The US National Renewable Energy Laboratory (NREL) in Golden, Colorado, has initiated a program that involves hybrid systems, to address these potential electricity opportunities in rural villages through the application of renewable energy technologies.1 The objective of this program is to develop and implement applications that demonstrate the technical performance, economic competitiveness, operational viability, and environmental benefits of renewable rural electric solutions, compared to the conventional options of line extension and isolated diesel mini-grids. Hybrid systems are multi-disciplinary, multi-technology, multi-application programs composed of six activities, including village applications development, computer model development, systems analysis, pilot project development, technical assistance, and Internet-based village power project data base. While the current program emphasizes wind, photovoltaics (PV), and their hybrids with diesel generator, micro-hydro and micro-biomass technologies may be integrated in the future. Thirteen countries are actively engaged in hybrid systems for rural and remote applications and another dozen countries have requested assistance in exploring wind/PV hybrid systems within their territories. At present rural/remote site application of renewable technologies is the fastest growing aspect of renewable energy worldwide.

Integration of renewable energies and nuclear power into North African Energy Systems: An analysis of energy import and export effects  

Science Journals Connector (OSTI)

The North African countries Morocco, Algeria, Tunisia, Libya and Egypt have been and are currently experiencing rapid growth in energy demand. This development confronts their political leaders with the question of how to expand or diversify their countries generation capacities. In this context, renewable energies and nuclear power constitute options that have rarely been exploited so far in the region. This article analyzes the drawbacks and benefits of both alternatives, with a special focus on import and export dynamics. When attempting to make the strategic decision between renewables and atomic power, North African regional specifics and circumstances have to be taken into account. Hence, in a first step, the article characterizes the energy systems of the North African countries and presents scenarios for their future development. In a second step, it scrutinizes the energy challenges these states face in terms of domestic concerns and foreign affairs. Finally, a case study of Algeria is used to demonstrate how renewable energies, but not nuclear power, are able to respond to North African energy challenges.

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.

SciTech Connect (OSTI)

The Renewable Electricity Futures (RE Futures) Study investigated the challenges and impacts of achieving very high renewable electricity generation levels in the contiguous United States by 2050. The analysis focused on the sufficiency of the geographically diverse U.S. renewable resources to meet electricity demand over future decades, the hourly operational characteristics of the U.S. grid with high levels of variable wind and solar generation, and the potential implications of deploying high levels of renewables in the future. RE Futures focused on technical aspects of high penetration of renewable electricity; it did not focus on how to achieve such a future through policy or other measures. Given the inherent uncertainties involved with analyzing alternative long-term energy futures as well as the multiple pathways that might be taken to achieve higher levels of renewable electricity supply, RE Futures explored a range of scenarios to investigate and compare the impacts of renewable electricity penetration levels (30%-90%), future technology performance improvements, potential constraints to renewable electricity development, and future electricity demand growth assumptions. RE Futures was led by the National Renewable Energy Laboratory (NREL) and the Massachusetts Institute of Technology (MIT).

Evaluation of renewable energy development in power generation in Finland  

Science Journals Connector (OSTI)

Renewable energy resources have historically played an important role for heat/electricity generation in Finland. Although diffusion costs of renewable energy utilization are higher than fossil fuels and nuclear power plants other policy aspects and operation costs of renewables cover this gap particularly in high dependent countries to fossil fuels. The current paper discusses the role of renewable portfolio in the Finland's energy action plan during 20112020. A system dynamics model is constructed to evaluate different costs of renewable energy utilization by 2020. Results show that total costs of new capacities of renewable energy systems as well as operation and maintenance costs of current systems bring 7% saving compared to total costs of new natural gas power plants (as a sample for second scenario) in Finland.

Communication Systems for Grid Integration of Renewable Energy Resources  

E-Print Network [OSTI]

There is growing interest in renewable energy around the world. Since most renewable sources are intermittent in nature, it is a challenging task to integrate renewable energy resources into the power grid infrastructure. In this grid integration, communication systems are crucial technologies, which enable the accommodation of distributed renewable energy generation and play extremely important role in monitoring, operating, and protecting both renewable energy generators and power systems. In this paper, we review some communication technologies available for grid integration of renewable energy resources. Then, we present the communication systems used in a real renewable energy project, Bear Mountain Wind Farm (BMW) in British Columbia, Canada. In addition, we present the communication systems used in Photovoltaic Power Systems (PPS). Finally, we outline some research challenges and possible solutions about the communication systems for grid integration of renewable energy resources.

China's Renewable Energy Law and its impact on renewable power in China: Progress, challenges and recommendations for improving implementation  

Science Journals Connector (OSTI)

Beginning in 2006, China experienced a rapid growth in its renewable energy resources, particularly wind power, placing it among the world's leading countries in terms of renewable energy installation and generation. This growth was greatly enabled by the renewable energy policy framework created by its landmark Renewable Energy Law, passed in 2005 and amended in 2009, which established key policies including: national renewable energy targets; a mandatory connection and purchase policy; a national feed-in tariff system; and arrangements for cost-sharing and funding of renewable energy incentives. This paper describes the mechanisms established by the Renewable Energy Law and its implementing regulations, as well as the challenges China continues to face in improving its renewable energy policy framework to improve integration and utilization of renewable energy sources. It also provides a comparison of the Chinese renewable energy policy framework with those in the European Union and United States. Finally, the paper provides recommendations for improving implementation of the Renewable Energy Law, with regard to implementing a renewable power quota system and priority dispatch policy, developing technical standards for connection of renewable resources with the grid, development of a more advanced feed-in tariff system, and central-local coordination of renewable energy development.

Renewable power needs smart storage solutions  

SciTech Connect (OSTI)

Ancient Greek philosopher Heraclitus claimed that the only thing constant in life is change, a truth we must accept and even celebrate. Another truth we face today is a growing demand for more energy to help us power the kind and pace of change weve become accustomed to, while minimizing environmental consequences. Renewable energy--two words that often find themselves woven into environmentally conscious dialogue. And according to Dave Lucero, director of alternative energy storage at EaglePicher Technologies LLC, the Tri-Cities should be thinking about two more: energy storage. Lucero recently addressed the Tri-Cities Research District about tackling the persistent challenge of maximizing renewable energy, which is inherently variable due to changing weather patterns. Capturing that energy and making it available for later use is vital.

Renewable Energy Positioning System: Energy Positioning: Control and Economics  

SciTech Connect (OSTI)

GENI Project: The University of Washington and the University of Michigan are developing an integrated system to match well-positioned energy storage facilities with precise control technologies so the electric grid can more easily include energy from renewable power sources like wind and solar. Because renewable energy sources provide intermittent power, it is difficult for the grid to efficiently allocate those resources without developing solutions to store their energy for later use. The two universities are working with utilities, regulators, and the private sector to position renewable energy storage facilities in locations that optimize their ability to provide and transmit electricity where and when it is needed most. Expanding the network of transmission lines is prohibitively expensive, so combining well-placed storage facilities with robust control systems to efficiently route their power will save consumers money and enable the widespread use of safe, renewable sources of power.

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.

Mini Renewable Hybrid Distributed Power Plants for Lebanon  

Science Journals Connector (OSTI)

Lebanon has spent billions of dollars on its electricity sector, but the demand is higher than available power. In peak demand time, blackouts are the major phenomena in almost all the Lebanese regions. As the world today is going into green energy, this project This step will minimize green house gas emissions, increase the reliability of the grid finally, increase the power generation capacity in Lebanon. For all the mentioned problems, distributed generation using hybrid-renewable energy systems is proposed as a future solution for the Lebanese energy sector. Losses in the transmission and distribution system will be reduced since power is generated near loads. The grid availability and stability will increase and individuals can save money in their electricity bill and finally the generated power is clean and nonpolluting. A study of a design will be launched, including simulation using MATLAB/SIMULINK.

The Treatment of Renewable Energy Certificates, EmissionsAllowances, and Green Power Programs in State Renewables PortfolioStandards  

SciTech Connect (OSTI)

Twenty-one states and the District of Columbia have adopted mandatory renewables portfolio standards (RPS) over the last ten years. Renewable energy attributes-such as the energy source, conversion technology, plant location and vintage, and emissions-are usually required to verify compliance with these policies, sometimes through attributes bundled with electricity, and sometimes with the attributes unbundled from electricity and traded separately as renewable energy certificates (RECs). This report summarizes the treatment of renewable energy attributes in state RPS rules. Its purpose is to provide a source of information for states considering RPS policies, and also to draw attention to certain policy issues that arise when renewable attributes and RECs are used for RPS compliance. Three specific issues are addressed: (1) the degree to which unbundled RECs are allowed under existing state RPS programs and the status of systems to track RECs and renewable energy attributes; (2) definitions of the renewable energy attributes that must be included in order to meet state RPS obligations, including the treatment of available emissions allowances; and (3) state policies on whether renewable energy or RECs sold through voluntary green power transactions may count towards RPS obligations.

Renewable Energy Options for a Utility System  

Science Journals Connector (OSTI)

In this paper renewable energies have been re?addressed with respect to the potentials and feasibility of being incorporated in process industries. Within a process utility system is considered to be the most appropriate place for using sustainable energies. For integrating the renewable energies the pinch analysis is applied as the main tool to provide opportunity for energy conservation. The results demonstrated that the power generation by the wind is the most cost effective and environmentally friendly option for energy conservation in comparison to the other sustainable resources. However the tidal energy stands the least due to the long payback period. Also a computer program has been developed using MATLAB 7.3 to screen out different scenarios and perform economic study. The outcome data showed that there are several different opportunities for the integration of alternative energies. Finally this method has been applied to a case study and various retrofit projects have been identified each of which has certain amount of CO 2 reduction and estimated values for the required investment saving potential and payback period.

GENI Project: MSU is developing a power flow controller to improve the routing of electricity from renewable sources through existing power lines. The fast, innovative, and lightweight circuitry that MSU is incorporating into its controller will eliminate the need for a separate heavy and expensive transformer, as well as the construction of new transmission lines. MSUs controller is better suited to control power flows from distributed and intermittent wind and solar power systems than traditional transformer-based controllers are, so it will help to integrate more renewable energy into the grid. MSUs power flow controller can be installed anywhere in the existing grid to optimize energy transmission and help reduce transmission congestion.

Barbose, and Edward Holt Pagination 49 Date Published 10/2010 Publisher LBNL City Berkeley Keywords electricity markets and policy group, energy analysis and environmental impacts department, photovoltaics, renewable energy, renewable energy policies Abstract Among the available options for encouraging the increased deployment of renewable electricity, renewables portfolio standards (RPS) have become increasingly popular. The RPS is a relatively new policy mechanism, however, and experience with its use is only beginning to emerge. One key concern that has been voiced is whether RPS policies will offer adequate support to a wide range of renewable energy technologies and applications or whether, alternatively, RPS programs will favor a small number of the currently least-cost forms of renewable energy. This report documents the design of and early experience with state-level RPS programs in the United States that have been specifically tailored to encourage a wider diversity of renewable energy technologies, and solar energy in particular. As shown here, state-level RPS programs specifically designed to support solar have already proven to be an important, albeit somewhat modest, driver for solar energy deployment, and those impacts are projected to continue to build in the coming years. State experience in supporting solar energy with RPS programs is mixed, however, and full compliance with existing requirements has not been achieved. The comparative experiences described herein highlight the opportunities and challenges of applying an RPS to specifically support solar energy, as well as the importance of policy design details to ensuring that program goals are achieved.

Renewable energy technologies for the Indian power sector: mitigation potential and operational strategies  

Science Journals Connector (OSTI)

The future economic development trajectory for India is likely to result in rapid and accelerated growth in energy demand, with attendant shortages and problems. Due to the predominance of fossil fuels in the generation mix, there are large negative environmental externalities caused by electricity generation. The power sector alone has a 40 percent contribution to the total carbon emissions. In this context, it is imperative to develop and promote alternative energy sources that can lead to sustainability of the energyenvironment system. There are opportunities for renewable energy technologies under the new climate change regime as they meet the two basic conditions to be eligible for assistance under UNFCCC mechanisms: they contribute to global sustainability through GHG mitigation; and, they conform to national priorities by leading to the development of local capacities and infrastructure. This increases the importance of electricity generation from renewables. Considerable experience and capabilities exist in the country on renewable electricity technologies. But a number of technoeconomic, market-related, and institutional barriers impede technology development and penetration. Although at present the contribution of renewable electricity is small, the capabilities promise the flexibility for responding to emerging economic, socioenvironmental and sustainable development needs. This paper discusses the renewable and carbon market linkages and assesses mitigation potential of power sector renewable energy technologies under global environmental intervention scenarios for GHG emissions reduction. An overall energy system framework is used for assessing the future role of renewable energy in the power sector under baseline and different mitigation scenarios over a time frame of 35 years, between 2000 to 2035. The methodology uses an integrated bottom-up modelling framework. Looking into past performance trends and likely future developments, analysis results are compared with officially set targets for renewable energy. The paper also assesses the CDM investment potential for power sector renewables. It outlines specific policy interventions for overcoming the barriers and enhancing deployment of renewables for the future.

Fuel Cell Electric Vehicle Powered by Renewable Hydrogen  

SciTech Connect (OSTI)

The National Renewable Energy Laboratory (NREL) recently received a Borrego fuel cell electric vehicle (FCEV) on loan from Kia for display at a variety of summer events. The Borrego is fueled using renewable hydrogen that is produced and dispensed at NREL's National Wind Technology Center near Boulder, Colorado. The hydrogen dispensed at the station is produced via renewable electrolysis as part of the wind-to-hydrogen project, which uses wind turbines and photovoltaic arrays to power electrolyzer stacks that split water into hydrogen and oxygen. The FCEV features state-of-the-art technology with zero harmful emissions.

Opportunities and Challenges of Integrating Renewable Energy in Smart Grid System  

Science Journals Connector (OSTI)

Abstract Smart grid technology is the key for an efficient use of distributed energy resources. Noting the climate change becomes an important issue the whole world is currently facing, the ever increasing price of petroleum products and the reduction in cost of renewable energy power systems, opportunities for renewable energy systems to address electricity generation seems to be increasing. However, to achieve commercialization and widespread use, an efficient energy management strategy of system needs to be addressed. Recently, the concept of smart grid has been successfully applied to the electric power systems. This paper presents the study of integrating renewable energy in smart grid system. The introductory sections provide the role of renewable energy and distributed generation in smart grid system. Subsequent sections cover the concept of smart grid as well as benefits and barrier of smart grid renewable energy system. Pricing is a significant variable in success of renewable energy promotion. Thus, it is important to gain insight to renewable energy pricing by considering unique characteristics associated with renewable energy alternatives. A review of work done in renewable smart grid systems in recent years indicates the promising potential of such research characteristics in the future. This would be useful to developers and practitioners of renewable energy systems and to policy makers.

Feasibility analysis of renewable energy powered tourism islandHainan, China  

Science Journals Connector (OSTI)

The current paper presents a feasibility analysis on a renewable energy dominated power structure in terms of both technological and economic considerations for Hainan Island China. To determine the optimal system configuration for a hybrid renewable energy system the software HOMER is used. The assessment criteria include net present cost cost of energy (COE) and carbon emission intensity (CEI). The modeling results demonstrate that renewable energy dominated power structures can meet the power demand of the island not only in 2010 but also in 2020 despite the almost doubled demand for electricity in 2020 assumed in our model. Thus building a nuclear power station in this location is unnecessary. The modeling results also show that the COE of the power system decreases from $0.074/kW h in 2010 to $0.051/kW h in 2020 as a result of the declining cost of renewable power equipment. Additionally CEI can be reduced by 69.2%74.9% against the current status. Sensitivity analysis shows that the correlation between interest rate and COE is linearly positive. However the relationship between gas prices and COE is not linearly positive because COE increases significantly faster than gas price does when it is less than $0.24/m3. A counter-intuitive phenomenon is found from the sensitivity analysis in which COE decreases with increasing carbon tax.

Modelling of Integrated Renewable Energy System  

Science Journals Connector (OSTI)

Energy is supplied in the form of electricity heat or fuels and an energy supply system must guarantee sufficient production and distribution of energy. An energy supply system based on renewable energy can be utilized as integrated renewable energy system (IRES) which can satisfy the energy needs of an area in appropriate & sustainable manner. Given the key role of renewable energy in rural electrification of remote rural areas the IRES for a given area can be modeled & optimized for meeting the energy needs. In the present paper Jaunpur block of Uttaranchal state of India has been selected as remote area. Based upon the data collected the resource potential and energy demand has been calculated & presented. The model on the basis of unit cost of the energy has been optimized using LINDO software 6.10 version. The results indicated that the optimized model has been found to the best choice for meeting the energy needs of the area. The results further indicated that for the above area either an IRES consisting of the above sources can provide a feasible solution in terms of energy fulfillments in the range of EPDF from 1.0 to 0.75.

Nuclear-renewable hybrid energy systems: Opportunities, interconnections, and needs  

SciTech Connect (OSTI)

As the U.S. energy system evolves, the amount of electricity from variable-generation sources is likely to increase, which could result in additional times when electricity demand is lower than available production. Thus, purveyors of technologies that traditionally have provided base-load electricitysuch as nuclear power plantscan explore new operating procedures to deal with the associated market signals. Concurrently, innovations in nuclear reactor design coupled with sophisticated control systems now allow for more complex apportionment of heat within an integrated system such as one linked to energy-intensive chemical processes. This paper explores one opportunity nuclear-renewable hybrid energy systems. These are defined as integrated facilities comprised of nuclear reactors, renewable energy generation, and industrial processes that can simultaneously address the need for grid flexibility, greenhouse gas emission reductions, and optimal use of investment capital. Six aspects of interaction (interconnections) between elements of nuclear-renewable hybrid energy systems are identified: Thermal, electrical, chemical, hydrogen, mechanical, and information. Additionally, system-level aspects affect selection, design, and operation of this hybrid system type. Throughout the paper, gaps and research needs are identified to promote further exploration of the topic.

Rethinking the Future Grid: Integrated Nuclear Renewable Energy Systems: Preprint  

SciTech Connect (OSTI)

The U.S. DOE is supporting research and development that could lead to more efficient utilization of clean energy generation sources, including renewable and nuclear options, to meet both grid demand and thermal energy needs in the industrial sector. One concept under consideration by the DOE-NE and DOE-EERE is tighter coupling of nuclear and renewable energy sources in a manner that better optimizes energy use for the combined electricity, industrial manufacturing, and transportation sectors. This integration concept has been referred to as a 'hybrid system' that is capable of apportioning thermal and electrical energy to first meet the grid demand (with appropriate power conversion systems), then utilizing excess thermal and, in some cases, electrical energy to drive a process that results in an additional product.

Integrating Variable Renewable Energy in Electric Power Markets: Best Practices from International Experience  

SciTech Connect (OSTI)

Many countries -- reflecting very different geographies, markets, and power systems -- are successfully managing high levels of variable renewable energy on the electric grid, including that from wind and solar energy. This study documents the diverse approaches to effective integration of variable renewable energy among six countries -- Australia (South Australia), Denmark, Germany, Ireland, Spain, and the United States (Western region-Colorado and Texas)-- and summarizes policy best practices that energy ministers and other stakeholders can pursue to ensure that electricity markets and power systems can effectively coevolve with increasing penetrations of variable renewable energy. Each country has crafted its own combination of policies, market designs, and system operations to achieve the system reliability and flexibility needed to successfully integrate renewables. Notwithstanding this diversity, the approaches taken by the countries studied all coalesce around five strategic areas: lead public engagement, particularly for new transmission; coordinate and integrate planning; develop rules for market evolution that enable system flexibility; expand access to diverse resources and geographic footprint of operations; and improve system operations. The ability to maintain a broad ecosystem perspective, to organize and make available the wealth of experiences, and to ensure a clear path from analysis to enactment should be the primary focus going forward.

Investigation into economical desalination using optimized hybrid renewable energy system  

Science Journals Connector (OSTI)

This paper investigates the use of hybrid renewable energy systems (HRESs) in Reverse Osmosis (RO) desalination. Mathematical model aided with a newly developed computer program for sizing (HRES) components. The study evaluates the individual and total expenses needed as well as the amount of excess renewable energy production. An optimization program was developed to select the best (HRES) combination that can produce desalinated water in a relatively economic cost. It demonstrates an investigated optimization approach based on minimization of the excess energy. It presents the impact of the considered optimization technique on the unit cost of energy and consequently unit cost of desalinated water. Unit production costs of both energy and desalinated water for two existing small and medium (RO) plants powered with conventional electricity grid are compared with the generated electricity from optimized (HRES). Cost sensitivity evaluation for (HRES) components to estimate the most economical price of (HRES) for desalination is presented.

Integrating Variable Renewable Energy in Electric Power Markets: Best Practices from International Experience, Summary for Policymakers  

SciTech Connect (OSTI)

Many countries -- reflecting very different geographies, markets, and power systems -- are successfully managing high levels of variable renewable energy on the electric grid, including that from wind and solar energy. This document summarizes policy best practices that energy ministers and other stakeholders can pursue to ensure that electricity markets and power systems can effectively coevolve with increasing penetrations of variable renewable energy. There is no one-size-fits-all approach; each country studied has crafted its own combination of policies, market designs, and system operations to achieve the system reliability and flexibility needed to successfully integrate renewables. Notwithstanding this diversity, the approaches taken by the countries studied all coalesce around five strategic areas: lead public engagement, particularly for new transmission; coordinate and integrate planning; develop rules for market evolution that enable system flexibility; expand access to diverse resources and geographic footprint of operations; and improve system operations. This study also emphatically underscores the value of countries sharing their experiences. The more diverse and robust the experience base from which a country can draw, the more likely that it will be able to implement an appropriate, optimized, and system-wide approach.

Transient stability and control of renewable generators based on Hamiltonian surface shaping and power flow control. Part II, analysis.  

SciTech Connect (OSTI)

The swing equations for renewable generators connected to the grid are developed and a wind turbine is used as an example. The swing equations for the renewable generators are formulated as a natural Hamiltonian system with externally applied non-conservative forces. A two-step process referred to as Hamiltonian Surface Shaping and Power Flow Control (HSSPFC) is used to analyze and design feedback controllers for the renewable generators system. This formulation extends previous results on the analytical verification of the Potential Energy Boundary Surface (PEBS) method to nonlinear control analysis and design and justifies the decomposition of the system into conservative and non-conservative systems to enable a two-step, serial analysis and design procedure. The first step is to analyze the system as a conservative natural Hamiltonian system with no externally applied non-conservative forces. The Hamiltonian surface of the swing equations is related to the Equal-Area Criterion and the PEBS method to formulate the nonlinear transient stability problem. This formulation demonstrates the effectiveness of proportional feedback control to expand the stability region. The second step is to analyze the system as natural Hamiltonian system with externally applied non-conservative forces. The time derivative of the Hamiltonian produces the work/rate (power flow) equation which is used to ensure balanced power flows from the renewable generators to the loads. The Second Law of Thermodynamics is applied to the power flow equations to determine the stability boundaries (limit cycles) of the renewable generators system and enable design of feedback controllers that meet stability requirements while maximizing the power generation and flow to the load. Necessary and sufficient conditions for stability of renewable generators systems are determined based on the concepts of Hamiltonian systems, power flow, exergy (the maximum work that can be extracted from an energy flow) rate, and entropy rate. This paper will present the analysis and numerical simulation results for two nonlinear control design examples that include: (1) the One-Machine Infinite Bus (OMIB) system with a Unified Power Flow Controller (UPFC) and (2) the swing equation for a wind turbine connected to an infinite bus through a UPFC to determine the required performance of the UPFC to enable the maximum power output of a wind turbine subject to stochastic inputs while meeting the power system constraints on frequency and phase. The energy storage requirements will also be identified from the UPFC and/or FACTS devices while working in combination with the wind turbine.

Methodology of risk analysis by Monte Carlo Method applied to power generation with renewable energy  

Science Journals Connector (OSTI)

Abstract This paper presents a methodology that uses the Monte Carlo Method (MCM) to estimate the behavior of economic parameters which may help decision, considering the risk in project sustainability. In order to show how this methodology can be used, a Grid-Connected Photovoltaic System (GCPVS) of 1.575kWp, located on the roof top of the laboratory building of the Grupo de Estudos e Desenvolvimento de Alternativas Energticas GEDAE, at the Universidade Federal do Par UFPA, Belm Par Brazil, and operating since December 2007, is analyzed. This system was chosen because it was the first GCPVS installed in the Brazilian Amazon Region, being the first risk evaluation on using a renewable energy source connected to the grid in the Region. This work also presents a similar treatment for the case of a stand-alone photovoltaic system (SAPVS) installed in the remote Santo Antnio Village, municipality of Breves, Par, Brazil, considering the risk of investment assumed by an investor in power generation projects with similar characteristics or using other renewable energy sources. The last case allows a better assessment for other important applications of renewable energy in the Amazon Region, where the demand for energy is growing, but is still costly and often not a priority in government actions.

Modelling of a smart micro grid with renewable energy for rural area based on power line communication  

Science Journals Connector (OSTI)

Renewable energy conversion systems are main factor driving research on smart grid technology. Smart grid represents the paradigm to enable highly efficient power generation, transmission, distribution and consumption from the source to consumer. Bangladesh is facing energy crisis like other developing countries. High energy demands and environmental concerns force the transformation of existing power grid into smart micro grid. This paper proposes power line communication-based (PLC) platform on dynamic demand response and distributed generation including renewable power generation management approach in the context of smart micro grid model for residential and industrial consumptions. The implementation of smart micro grid to a rural area promotes the utilisation of renewable resources such as solar and wind energy. In this model, deployed PLC networks, data management system to integrate sensors, switchgears, transformers and other utility devices are used to interconnect smart homes to smart grids. Analytical results show the effectiveness of the proposed system to optimise residential renewable energy generation and smart meters to improve electrical grid control and energy conservation system.

Assessment of H2- and H2O-based renewable energy-buffering systems in minor islands  

Science Journals Connector (OSTI)

The paper assesses the energy and environmental performance of two solutions designed to complement renewable energy (RE) technologies, in stand-alone power system (SAPS) configuration typical of minor Mediterranean islands, by converting the available RE surplus. The studied SAPS, based on the Ventotene island demographic, meteorological and load data, features high renewable energy penetration onto the load power demand, i.e. up to 55.25% share of peak power capacity. Transient models have been developed to simulate the storage process of winter renewable energy surplus and the time-dependent matching among SAPS electric demand and the stochastic renewable power contributions combined with energy surplus conversion systems. The study compares a hydrogen-based system and a desalinated water-production system, proposed as two effective alternatives for renewable energy seasonal buffering in an island context. The comparative analysis of the time-dependent system's behaviour has been investigated with an hourly distribution over the period of one reference year, in terms of fuel consumption and hydrogen system energy storage or desalination capacity. The assessment is carried out by taking performance indicators, SAPS fuel savings, as well as stored and dump power data. The study demonstrates the suitability of both the models for the winter renewable energy buffer, in order to improve to the matching of peak energy and water demands.

Feasibility study and economic analysis of pumped hydro storage and battery storage for a renewable energy powered island  

Science Journals Connector (OSTI)

Abstract This study examined and compared two energy storage technologies, i.e. batteries and pumped hydro storage (PHS), for the renewable energy powered microgrid power supply system on a remote island in Hong Kong. The problems of energy storage for off-grid renewable energy were analyzed. The sizing methods and economic models were developed, and finally applied in the real project (case study). The results provide the most suitable energy storage scheme for local decision-makers. The two storage schemes were further divided into 4 options. Accordingly, the life-cycle costs (LCC), levelized costs for the renewable energy storage system (LCRES) and the LCC ratios between all options were calculated and compared. It was found that the employment of conventional battery (Option 2) had a higher LCC value than the advanced deep cycle battery (Option 1), indicating that using deep cycle batteries is more suitable for a standalone renewable power supply system. The pumped storage combined with battery bank option (Option 3) had only 55% LCC of that of Option 1, making this combined option more cost-competitive than the sole battery option. The economic benefit of pumped storage is even more significant in the case of purely pumped storage with a hydraulic controller (Option 4), with the lowest LCC among all options at 2948% of Option 1. Sensitivity analysis demonstrates that PHS is even more cost competitive by controlling some adjustments such as increasing energy storage capacity and days of autonomy. Therefore, the renewable energy system coupled with pumped storage presents technically feasible opportunities and practical potential for continuous power supply in remote areas.

Integrating Variable Renewable Energy in Electric Power Markets: Best Practices from International Experience (Fact Sheet)  

SciTech Connect (OSTI)

Many countries--reflecting very different geographies, markets, and power systems--are successfully managing high levels of variable renewable energy (RE) on the grid. Australia (South Australia), Denmark, Germany, Ireland, Spain, and the United States (Colorado and Texas), for example, have effectively integrated variable RE utilizing diverse approaches. Analysis of the results from these case studies reveals a wide range of mechanisms that can be used to accommodate high penetrations of variable RE (e.g., from new market designs to centralized planning). Nevertheless, the myriad approaches collectively suggest that governments can best enable variable RE grid integration by implementing best practices in five areas of intervention: lead public engagement, particularly for new transmission; coordinate and integrate planning; develop rules for market evolution that enable system flexibility; expand access to diverse resources and geographic footprint of operations; and improve system operations.

A Stochastic Calculus for Network Systems with Renewable Energy Sources  

E-Print Network [OSTI]

We consider the performance modeling and evaluation of network systems powered with renewable energy sources such as solar and wind energy. Such energy sources largely depend on environmental conditions, which are hard to predict accurately. As such, it may only make sense to require the network systems to support a soft quality of service (QoS) guarantee, i.e., to guarantee a service requirement with a certain high probability. In this paper, we intend to build a solid mathematical foundation to help better understand the stochastic energy constraint and the inherent correlation between QoS and the uncertain energy supply. We utilize a calculus approach to model the cumulative amount of charged energy and the cumulative amount of consumed energy. We derive upper and lower bounds on the remaining energy level based on a stochastic energy charging rate and a stochastic energy discharging rate. By building the bridge between energy consumption and task execution (i.e., service), we study the QoS guarantee under...

Review of transmission schemes and case studies for renewable power integration into the remote grid  

Science Journals Connector (OSTI)

Investment in transmission for renewable power penetration to the remote grid essentially faces a set of inherent, regulatory, economic and technical challenges. This work investigates these challenges to enhance renewable power integration into the remote grid. This study aims to enhance regulatory policies and associated planning frameworks to be more efficient and justifiable for renewable power integration paradigm. First, a set of leading transmission schemes practiced, or investigated, in different countries are evaluated against the challenges which are obvious for long distance renewable power transmission. Second, a net benefit framework is presented to address the challenging issues of location constrained renewable power penetration into the Queensland network of the Australian grid. The proposed framework incorporates the carbon emission price as an environmental benefit which significantly influences the costbenefit analysis. This paper discusses the hub approach of network integration. The transmission investment cost allocation is addressed here as well. The concepts are verified through the implementation of the proposed framework in four prospective projects of the Queensland network in the Australian national electricity market (NEM).

Determining the best source of renewable electricity to power a remote site for the National Park Service  

SciTech Connect (OSTI)

Renewable energy technologies have economic and environmental advantages in many remote applications. They can provide most of the power to off-grid loads, where batteries and another power source such as a generator or a fuel cell may be required to ensure availability and feasibility. In support of the National Park Service, the Federal Energy Management Program Team at the National Renewable Energy Laboratory has evaluated several methods for providing a renewable source of electricity to a beach campsite at Kirby Cove, Marin County, California. This site requires 2 kWh per day to power a campground host in a motor home five months power year. The existing electricity line to the site is in need of replacement and the NPS is interested in evaluating more cost-effective and environmentally sensitive alternatives. Photovoltaics, tidal current, and wind power systems in combination with a back-up electric system (standard, thermoelectric, and Stirling generator and fuel cell) and an energy storage medium (battery, flywheel, and hydrogen) were analyzed. Multi-objective optimization criteria include initial cost, operating cost, emissions, maintenance requirements, and to be consistent with the NPS requirements, the system must be clean, silent, and sustainable. The best system combination was designed according to these evaluation criteria and a demonstration system is to be constructed. This paper describes the optimization procedure and design. Results indicate that a 800 Watt photovoltaic array with a hydrogen fuel cell best serves the requirements for clean, silent power. Since fuel cells are developmental, a propane generator is recommended as an alternative.

Adaptations of renewable energy policies to unstable macroeconomic situationsCase study: Wind power in Brazil  

Science Journals Connector (OSTI)

Despite the massive cost reduction in the last decade, wind power generation is generally still more expensive than conventional energy sources which benefit from the exclusion of externality costs in the price structure. Support policies for renewable energies guarantee the economic viability of this type of electrical power generation in many European countries. In Latin America, Brazil has become the pioneer state for renewable energy with the implementation of the PROINFA programme that supports, among other sources, wind power development of 1100MW. This article presents an overview of the differences between the German and Brazilian wind power promotion policies with a special focus on how PROINFA can be adapted to the unstable macroeconomic situation of Brazil. The document specifically examines the adaptation of wind power promotion policies to large inflation and interest rates in Brazil.

Catalog of DC Appliances and Power Systems Catalog of DC Appliances and Power Systems Title Catalog of DC Appliances and Power Systems Publication Type Report LBNL Report Number LBNL-5364E Year of Publication 2011 Authors Garbesi, Karina, Vagelis Vossos, and Hongxia Shen Document Number LBNL-5364E Date Published October Publisher Lawrence Berkeley National Laboratory Abstract This document catalogs the characteristics of current and potential future direct current (DC) products and power systems. It is part of a larger U.S. Department of Energy-funded project, "Direct-DC Power Systems for Energy Efficiency and Renewable Energy Integration with a Residential and Small Commercial Focus". That project is investigating the energy-savings potential, benefits, and barriers of using DC generated by on-site renewable energy systems directly in its DC form, rather than converting it first to alternating current (AC) for distribution to loads. Two related reports resulted from this work: this Catalog and a companion report that addresses direct-DC energy savings in U.S. residential buildings.Interest in 'direct-DC' is motivated by a combination of factors: the very rapid increase in residential and commercial photovoltaic (PV) power systems in the United States; the rapid expansion in the current and expected future use of energy efficient products that utilize DC power internally; the demonstrated energy savings of direct-DC in commercial data centers; and the current emergence of direct-DC power standards and products designed for grid-connected residential and commercial products. Based on an in-depth study of DC appliances and power systems, we assessed off-grid markets for DC appliances, the DC compatibility of mainstream electricity end-uses, and the emerging mainstream market for direct-DC appliances and power systems.

Energy storage for desalination processes powered by renewable energy and waste heat sources  

Science Journals Connector (OSTI)

Abstract Desalination has become imperative as a drinking water source for many parts of the world. Due to the large quantities of thermal energy and high quality electricity requirements for water purification, the desalination industry depends on waste heat resources and renewable energy sources such as solar collectors, photovoltaic arrays, geothermal and wind and tidal energy sources. Considering the mismatch between the source supply and demand and intermittent nature of these energy resources, energy storage is a must for reliable and continuous operation of desalination facilities. Thermal energy storage (TES) requires a suitable medium for storage and circulation while the photovoltaic/wind generated electricity needs to be stored in batteries for later use. Desalination technologies that utilize thermal energy and thus require storage for uninterrupted process operation are multi-stage flash distillation (MSF), multi-effect evaporation (MED), low temperature desalination (LTD) and humidificationdehumidification (HD) and membrane distillation (MD). Energy accumulation, storage and supply are the key components of energy storage concept which improve process performance along with better resource economics, and minimum environmental impact. Similarly, the battery energy storage (BES) is essential to store electrical energy for electrodialysis (ED), reverse osmosis (RO) and mechanical vapor compression (MVC) technologies. This research-review paper provides a critical review on current energy storage options for different desalination processes powered by various renewable energy and waste heat sources with focus on thermal energy storage and battery energy storage systems. Principles of energy storage (thermal and electrical energy) are discussed with details on the design, sizing, and economics for desalination process applications.

NSTX Electrical Power Systems  

SciTech Connect (OSTI)

The National Spherical Torus Experiment (NSTX) has been designed and installed in the existing facilities at Princeton Plasma Physic Laboratory (PPPL). Most of the hardware, plant facilities, auxiliary sub-systems, and power systems originally used for the Tokamak Fusion Test Reactor (TFTR) have been used with suitable modifications to reflect NSTX needs. The design of the NSTX electrical power system was tailored to suit the available infrastructure and electrical equipment on site. Components were analyzed to verify their suitability for use in NSTX. The total number of circuits and the location of the NSTX device drove the major changes in the Power system hardware. The NSTX has eleven (11) circuits to be fed as compared to the basic three power loops for TFTR. This required changes in cabling to insure that each cable tray system has the positive and negative leg of cables in the same tray. Also additional power cabling had to be installed to the new location. The hardware had to b e modified to address the need for eleven power loops. Power converters had to be reconnected and controlled in anti-parallel mode for the Ohmic heating and two of the Poloidal Field circuits. The circuit for the Coaxial Helicity Injection (CHI) System had to be carefully developed to meet this special application. Additional Protection devices were designed and installed for the magnet coils and the CHI. The thrust was to making the changes in the most cost-effective manner without compromising technical requirements. This paper describes the changes and addition to the Electrical Power System components for the NSTX magnet systems.

Flexibility in 21st Century Power Systems (Fact Sheet)  

SciTech Connect (OSTI)

Flexibility of operation--the ability of a power system to respond to change in demand and supply--is a characteristic of all power systems. Flexibility is especially prized in twenty-first century power systems, with higher levels of grid-connected variable renewable energy (primarily, wind and solar). Sources of flexibility exist--and can be enhanced--across all of the physical and institutional elements of the power system, including system operations and markets, demand side resources and storage; generation; and transmission networks. Accessing flexibility requires significant planning to optimize investments and ensure that both short- and long-time power system requirements are met.

Recognition also is growing that our air and land can no longer absorb unlimited quantities of waste from fossil fuel extraction and combustion. As that day draws nearer, policymakers will have no realistic alternative but to turn to sources of power that today make up a viable but small part of America's energy picture. And they will be forced to embrace energy efficiencies - those that are within our reach today, and those that will be developed tomorrow. Precisely when they come lo grips with that reality - this year, 10 years from now, or 20 years from now - will determine bow smooth the transition will be for consumers and industry alike.

Wind power generating system  

SciTech Connect (OSTI)

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.

Scenarios for the role of hydrogen in a future energy system based on renewable energy  

Science Journals Connector (OSTI)

An all-renewable energy system for a group of North European countries is investigated by temporal simulation of the demand-supply matching for various system configurations. The role of hydrogen technologies for energy storage and fuel cell applications is studied and applied to both stationary and transportation sectors. It is shown that there is scope for considerable amounts of energy trade between the countries, owing to the different endowment of different countries with particular renewable energy sources, and to the particular benefit that intermittent energy sources such as wind and solar can derive from the exchange of power. A smooth energy supply is demonstrated by use of the seasonal reservoir-based hydro components in the northern parts of the region. Comments are also made on the competition between biofuels and hydrogen in the transportation sector.

SciTech Connect (OSTI)

ORPC Maine, LLC, a wholly-owned subsidiary of Ocean Renewable Power Company, LLC (collectively ORPC), submits this Final Technical Report for the TidGen Power System Commercialization Project (Project), partially funded by the U.S. Department of Energy (DE-EE0003647). The Project was built and operated in compliance with the Federal Energy Regulatory Commission (FERC) pilot project license (P-12711) and other permits and approvals needed for the Project. This report documents the methodologies, activities and results of the various phases of the Project, including design, engineering, procurement, assembly, installation, operation, licensing, environmental monitoring, retrieval, maintenance and repair. The Project represents a significant achievement for the renewable energy portfolio of the U.S. in general, and for the U.S. marine hydrokinetic (MHK) industry in particular. The stated Project goal was to advance, demonstrate and accelerate deployment and commercialization of ORPCs tidal-current based hydrokinetic power generation system, including the energy extraction and conversion technology, associated power electronics, and interconnection equipment capable of reliably delivering electricity to the domestic power grid. ORPC achieved this goal by designing, building and operating the TidGen Power System in 2012 and becoming the first federally licensed hydrokinetic tidal energy project to deliver electricity to a power grid under a power purchase agreement in North America. Located in Cobscook Bay between Eastport and Lubec, Maine, the TidGen Power System was connected to the Bangor Hydro Electric utility grid at an on-shore station in North Lubec on September 13, 2012. ORPC obtained a FERC pilot project license for the Project on February 12, 2012 and the first Maine Department of Environmental Protection General Permit issued for a tidal energy project on January 31, 2012. In addition, ORPC entered into a 20-year agreement with Bangor Hydro Electric Company on January 1, 2013 for up to 5 megawatts at a price of $215/MWh, escalating at 2.0% per year.

Advanced photovoltaic/hydro hybrid renewable energy system for remote areas  

Science Journals Connector (OSTI)

This paper presents modeling and simulation of the advanced photovoltaic (PV)/hydro based Hybrid Renewable Energy System (HRES) to electrify such isolated/remote areas where grid accessibility is not possible. For 7.5?kW hydro generation system a Self Excited Induction Generator (SEIG) with improved technique is used to optimize the utilization of hydro power. To achieve this aim an uncontrolled bridge rectifier coupled with Hydro side Voltage Source Inverter is implemented for the SEIG based advanced hydro system. The PV system is configured by PV array battery DC/DC converter maximum power point tracking controller and PV side Voltage Source Inverter. A Constant Current Control scheme is developed in this paper to control active and reactive power flow and to synchronize hydro and PV systems. The proposed system uses fewer controlled switches hence complexity of control has been reduced and system has higher efficiency and lower switching losses. The performance analysis of the HRES has been done to authenticate the existence of the system using the MATLAB software and results demonstrate that power quality of the proposed system is better and HRES is able to put into services.

renewable fuels module (RFM) consists of five submodules that represent the various types of renewable energy technologies used for grid-connected U.S. electricity supply (Figure 11). Since most renewables (wind, solar, and geothermal) are used to generate electricity, the interaction with the electricity market module (EMM) is important for modeling grid-connected renewable-electric applications. The penetration of grid-connected generation technologies, with the exception of municipal solid waste, is determined by EMM. Hydropower is included in EMM directly. renewable fuels module (RFM) consists of five submodules that represent the various types of renewable energy technologies used for grid-connected U.S. electricity supply (Figure 11).

Increasing the renewable energy sources absorption capacity of the Macedonian energy system  

Science Journals Connector (OSTI)

Macedonian energy sector is the main emitter of greenhouse gases with share of about 70% in the total annual emissions. Also 70%75% of emissions are associated with the electricity generation due to the predominant role of the lignite fuelled power plants. Recently the government has adopted a strategy for the use of renewable energy sources (RES) which identifies a target of 21% of final energy consumption from RES by 2020. In this paper analyses are conducted in order to investigate to which extent and in which way the absorption capacity of the power system for RES electricity can be improved. For this purpose combining various conventional and RES technologies including pump storage hydro power plant and revitalisation of the existing lignite power plants six scenarios for the power system expansion are developed by making use of EnergyPLAN model. Critical excess of electricity analyses are conducted in order to identify the maximal penetration of wind electricity. The results have shown that in the exiting capacities maximal penetration of wind electricity in 2020 is 13% of total electricity consumption. The revitalization of the existing lignite power plants and building of pump storage power plant would increase the wind penetration. Furthermore the developed scenarios are comparatively assessed in terms of the associated greenhouse gases emissions and import of electricity.

A demand side management strategy based on forecasting of residential renewable sources: A smart home system in Turkey  

Science Journals Connector (OSTI)

Abstract The existing electricity systems have been substantially designed to allow only centralized power generation and unidirectional power flow. Therefore, the objective of improving the conventional power systems with the capabilities of decentralized generation and advanced control has conflicted with the present power system infrastructure and thus a profound change has necessitated in the current power grids. To that end, the concept of smart grid has been introduced at the last decades in order to accomplish the modernization of the power grid while incorporating various capabilities such as advanced metering, monitoring and self-healing to the systems. Among the various advanced components in smart grid structure, smart home is of vital importance due to its handling difficulties caused by the stochastic behaviors of inhabitants. However, limited studies concerning the implementation of smart homes have so far been reported in the literature. Motivated by this need, this paper investigates an experimental smart home with various renewable energy sources and storage systems in terms of several aspects such as in-home energy management, appliances control and power flow. Furthermore, the study represents one of the very first attempts to evaluate the contribution of power forecasting of renewable energy sources on the performance of smart home concepts.

Design and feasibility study of a microgeneration system to obtain renewable energy from tidal currents  

Science Journals Connector (OSTI)

Tidal energy to obtain electrical energy is yet an unexploited renewable energy. Existing generator designs and prototypes are not feasible due to the high investment conditioned by their high rated powers and off-shore locations. In addition these prototypes are not readily available. This investigation presents a design of a microgeneration system with vertical axis microturbines. The design of the microturbines utilizes off-the-shelf electronic components thus reducing the initial investment. The nominal data for selection of power electronic components and the total energy that can be obtained in a year are calculated. The investigation also studies the feasibility of an 80?kW microgeneration system to be applied in Spain taking advantage of the actual electricity prices. The feasibility study quantifies the influence of the parameters: initial investment tidal current speed operation hours turbine efficiency price of electricity and number of microturbines obtaining the limiting values of the suitable scenarios.

Impacts of Western Area Power Administration`s power marketing alternatives on utility demand-side management and conservation and renewable energy programs  

SciTech Connect (OSTI)

The Western Area Power Administration (Western) requires all of its long-term firm power customers to implement programs that promote the conservation of electric energy or facilitate the use of renewable energy resources. Western has also proposed that all customers develop integrated resource plans that include cost-effective demand-side management programs. As part of the preparation of Western`s Electric Power Marketing Environmental Impact Statement, Argonne National Laboratory (ANL) developed estimates of the reductions in energy demand resulting from Western`s conservation and renewable energy activities in its Salt Lake City Area Office. ANL has also estimated the energy-demand reductions from cost-effective, demand-side management programs that could be included in the integrated resource plans of the customers served by Western`s Salt Lake City Area Office. The results of this study have been used to adjust the expected hourly demand for Western`s major systems in the Salt Lake City Area. The expected hourly demand served as the basis for capacity expansion plans develops with ANL`s Production and Capacity Expansion (PACE) model.

The focus of the LDRD was to develop decisionsupport technologies to enable rational and quantifiable risk management for two key grid operational timescales: scheduling (day-ahead) and planning (month-to-year-ahead). Risk or resiliency metrics are foundational in this effort. The 2003 Northeast Blackout investigative report stressed the criticality of enforceable metrics for system resiliency - the grid's ability to satisfy demands subject to perturbation. However, we neither have well-defined risk metrics for addressing the pervasive uncertainties in a renewable energy era, nor decision-support tools for their enforcement, which severely impacts efforts to rationally improve grid security. For day-ahead unit commitment, decision-support tools must account for topological security constraints, loss-of-load (economic) costs, and supply and demand variability - especially given high renewables penetration. For long-term planning, transmission and generation expansion must ensure realized demand is satisfied for various projected technological, climate, and growth scenarios. The decision-support tools investigated in this project paid particular attention to tailoriented risk metrics for explicitly addressing high-consequence events. Historically, decisionsupport tools for the grid consider expected cost minimization, largely ignoring risk and instead penalizing loss-of-load through artificial parameters. The technical focus of this work was the development of scalable solvers for enforcing risk metrics. Advanced stochastic programming solvers were developed to address generation and transmission expansion and unit commitment, minimizing cost subject to pre-specified risk thresholds. Particular attention was paid to renewables where security critically depends on production and demand prediction accuracy. To address this concern, powerful filtering techniques for spatio-temporal measurement assimilation were used to develop short-term predictive stochastic models. To achieve uncertaintytolerant solutions, very large numbers of scenarios must be simultaneously considered. One focus of this work was investigating ways of reasonably reducing this number.

This report discusses Test Campaign TC12 of the Kellogg Brown & Root, Inc. (KBR) Transport Gasifier train with a Siemens Westinghouse Power Corporation (SW) particle filter system at the Power Systems Development Facility (PSDF) located in Wilsonville, Alabama. The Transport Gasifier is an advanced circulating fluidized-bed reactor designed to operate as either a combustor or a gasifier using a particulate control device (PCD). While operating as a gasifier, either air or oxygen can be used as the oxidant. Test run TC12 began on May 16, 2003, with the startup of the main air compressor and the lighting of the gasifier start-up burner. The Transport Gasifier operated until May 24, 2003, when a scheduled outage occurred to allow maintenance crews to install the fuel cell test unit and modify the gas clean-up system. On June 18, 2003, the test run resumed when operations relit the start-up burner, and testing continued until the scheduled end of the run on July 14, 2003. TC12 had a total of 733 hours using Powder River Basin (PRB) subbituminous coal. Over the course of the entire test run, gasifier temperatures varied between 1,675 and 1,850 F at pressures from 130 to 210 psig.

Life-cycle analysis results of geothermal systems in comparison to other power systems.  

SciTech Connect (OSTI)

A life-cycle energy and greenhouse gas emissions analysis has been conducted with Argonne National Laboratory's expanded Greenhouse Gases, Regulated Emissions, and Energy Use in Transportation (GREET) model for geothermal power-generating technologies, including enhanced geothermal, hydrothermal flash, and hydrothermal binary technologies. As a basis of comparison, a similar analysis has been conducted for other power-generating systems, including coal, natural gas combined cycle, nuclear, hydroelectric, wind, photovoltaic, and biomass by expanding the GREET model to include power plant construction for these latter systems with literature data. In this way, the GREET model has been expanded to include plant construction, as well as the usual fuel production and consumption stages of power plant life cycles. For the plant construction phase, on a per-megawatt (MW) output basis, conventional power plants in general are found to require less steel and concrete than renewable power systems. With the exception of the concrete requirements for gravity dam hydroelectric, enhanced geothermal and hydrothermal binary used more of these materials per MW than other renewable power-generation systems. Energy and greenhouse gas (GHG) ratios for the infrastructure and other life-cycle stages have also been developed in this study per kilowatt-hour (kWh) of electricity output by taking into account both plant capacity and plant lifetime. Generally, energy burdens per energy output associated with plant infrastructure are higher for renewable systems than conventional ones. GHG emissions per kWh of electricity output for plant construction follow a similar trend. Although some of the renewable systems have GHG emissions during plant operation, they are much smaller than those emitted by fossil fuel thermoelectric systems. Binary geothermal systems have virtually insignificant GHG emissions compared to fossil systems. Taking into account plant construction and operation, the GREET model shows that fossil thermal plants have fossil energy use and GHG emissions per kWh of electricity output about one order of magnitude higher than renewable power systems, including geothermal power.

Effective utilization of excess energy in standalone hybrid renewable energy systems for improving comfort ability and reducing cost of energy: A review and analysis  

Science Journals Connector (OSTI)

Abstract One of the features that characterize renewable energy sources is their variability and intermittency. Intermittency covers both the predictable and unpredictable variations of their power outputs and uncertainty in the power availability. To overcome the drawback of intermittency, special design considerations should be taken into account. These additional design considerations increases the overall cost of the renewable energy systems. Adding storage system and/or backup source to the renewable sources is one of the measures used to guarantee the continuity of power supply to the loads, and therefore improve the reliability of the renewable energy systems. The operation of renewable energy systems results in the creation of surplus energy, which is the energy generated by renewable energy systems, but is not consumed by the loads in standalone power systems. Effective utilization of this excess energy has the potential to decrease the cost of energy (COE) production by these hybrid renewable energy systems. In this paper, a review of the literature will be carried out in order to provide further insight into the approaches suggested in the literature on how to deal with the utilization of excess energy. Furthermore, various possible configurations of hybrid systems will be analyzed in detail for the effective utilization of the excess energy produced by hybrid systems. This is done in order to evaluate the effectiveness of utilization of excess energy by various means, especially for improving the living space comfort ability and decreasing the COE. Case studies will be carried out to demonstrate the proposed configurations for the effective utilization of the excess energy, and the results will be presented.

Renewable build-up pathways for the US: Generation costs are not system costs  

E-Print Network [OSTI]

The transition to a future electricity system based primarily on wind and solar PV is examined for all regions in the contiguous US. We present optimized pathways for the build-up of wind and solar power for least backup energy needs as well as for least cost obtained with a simplified, lightweight model based on long-term high resolution weather-determined generation data. In the absence of storage, the pathway which achieves the best match of generation and load, thus resulting in the least backup energy requirements, generally favors a combination of both technologies, with a wind/solar PV energy mix of about 80/20 in a fully renewable scenario. The least cost development is seen to start with 100% of the technology with the lowest average generation costs first, but with increasing renewable installations, economically unfavorable excess generation pushes it toward the minimal backup pathway. Surplus generation and the entailed costs can be reduced significantly by combining wind and solar power, and/or a...

Renewable energy of waste heat recovery system for automobiles  

Science Journals Connector (OSTI)

A system to recover waste heat comprised of eight thermoelectric generators (TEGs) to convert heat from the exhaust pipe of an automobile to electrical energy has been constructed. Simulations and experiments for the thermoelectric module in this system are undertaken to assess the feasibility of these applications. In order to estimate the temperature difference between thermoelectric elements a network of thermal resistors is constructed. The results assist in predicting power output of TEG module more precisely. Three configurations of heat sinks which are comprised of 10 22 and 44 fins are applied in this simulation. The results of the simulations show the average thermal resistance of these heat sinks in each section of the system with varied velocity of external flow. As the performance of a TEG module is influenced by an applied pressure through the effect of the thermal contact resistance we clamp the TE module to our experimental apparatus; the relation between power output and pressure applied in this case is presented. Besides simulations the system is designed and assembled. Measurements followed the connection of the system to the middle of an exhaust pipe. Through these simulations and experiments the power generated with a commercial TEG is presented. The results establish the fundamental development of materials that enhance the TEG efficiency for vehicles.

Energy Storage for Variable Renewable Energy Resource Integration - A Regional Assessment for the Northwest Power Pool (NWPP)  

SciTech Connect (OSTI)

This paper addresses the following key questions in the discussion on the integration of renewable energy resources in the Pacific Northwest power grid: a) what will be the future balancing requirement to accommodate a simulated expansion of wind energy resources from 3.3 GW in 2008 to 14.4 GW in 2019 in the Northwest Power Pool (NWPP), and b) what are the most cost effective technological solutions for meeting the balancing requirements in the Northwest Power Pool (NWPP). A life-cycle analysis was performed to assess the least-cost technology option for meeting the new balancing requirement. The technologies considered in this study include conventional turbines (CT), sodium sulfur (NaS) batteries, lithium ion (Li-ion) batteries, pumped hydro energy storage (PH), and demand response (DR). Hybrid concepts that combine 2 or more of the technologies above are also evaluated. This analysis was performed with collaboration by the Bonneville Power Administration and funded by the Energy Storage Systems Program of the U.S. Department of Energy.

The Applied Mathematics for Power Systems (AMPS)  

SciTech Connect (OSTI)

Increased deployment of new technologies, e.g., renewable generation and electric vehicles, is rapidly transforming electrical power networks by crossing previously distinct spatiotemporal scales and invalidating many traditional approaches for designing, analyzing, and operating power grids. This trend is expected to accelerate over the coming years, bringing the disruptive challenge of complexity, but also opportunities to deliver unprecedented efficiency and reliability. Our Applied Mathematics for Power Systems (AMPS) Center will discover, enable, and solve emerging mathematics challenges arising in power systems and, more generally, in complex engineered networks. We will develop foundational applied mathematics resulting in rigorous algorithms and simulation toolboxes for modern and future engineered networks. The AMPS Center deconstruction/reconstruction approach 'deconstructs' complex networks into sub-problems within non-separable spatiotemporal scales, a missing step in 20th century modeling of engineered networks. These sub-problems are addressed within the appropriate AMPS foundational pillar - complex systems, control theory, and optimization theory - and merged or 'reconstructed' at their boundaries into more general mathematical descriptions of complex engineered networks where important new questions are formulated and attacked. These two steps, iterated multiple times, will bridge the growing chasm between the legacy power grid and its future as a complex engineered network.

Wide scale penetration of renewable electricity in the Greek energy system in view of the European decarbonization targets for 2050  

Science Journals Connector (OSTI)

Abstract The key policy analyzed in this paper, is the achievement of a significant decarbonization of the Greek Energy System by the year 2050 through the decarbonization of the two sectors presently responsible for the highest levels of greenhouse gas emissions (GHG) emissions, namely power and transport. The objective is to reduce GHG emissions by 2050, through the maximization of renewable energy sources (RES) penetration in electricity, with a simultaneous intensive electrification of the transport sector and the electrical interconnection of non-connected islands. An important parameter considered in the present work is that expansion planning of power systems under environmental constraints leads to a rather complex techno-economic analysis involving large scale penetration of Renewable Energy Sources. The penetration level of variable renewable electricity is subject to a number of restrictions implied by the need for (a) storage capacity to decrease the energy curtailment which can occur when the customer load is low and RES electricity generation is high (b) fast reserve capacity to deal with variations of variable RES or combined heat and power (CHP) electricity generation (c) transmission system expansion related to the penetration of areas with high RES potential. New methodologies are developed and a number of novel scenarios are formulated in conformity with the European energy strategy towards 2050.

PTC, ITC, or Cash Grant? An Analysis of the Choice Facing Renewable Power Projects in the United States  

SciTech Connect (OSTI)

Renewable power technologies are inherently capital-intensive, often (but not always) with relatively high construction costs and low operating costs. For this reason, renewable power technologies are typically more sensitive to the availability and cost of financing than are natural gas power plants, for example. In the United States, the bulk of renewable project finance in recent years has been provided by 'tax equity investors' (typically large investment banks and insurance companies) who partner with project developers through highly specialized financing structures (Bolinger, 2009; Cory et al., 2008; Harper et al., 2007). These structures have been designed primarily to capitalize on federal support for renewable power technologies, which has historically come in the form of tax credits and accelerated depreciation deductions. The number of tax equity investors active in the renewable power market has declined precipitously, however, as a result of the financial crisis that began unfolding across the globe in the summer of 2008. The resulting shortage and increased cost of project financing has, in turn, slowed the development of new renewable power projects, leading to layoffs throughout the entire industry supply chain. In recognition of the fact that tax-based policy incentives are not particularly effective when tax burdens are shrinking or non-existent, Congress included several provisions in 'The American Recovery and Reinvestment Act of 2009' (ARRA 2009) designed to make federal incentives for renewable power technologies more useful. Among these provisions is one that allows projects eligible to receive the production tax credit ('the PTC', see Text Box 1) to instead elect the investment tax credit ('the ITC', see Text Box 2). Another provision enables ITC-eligible projects (which now include most PTC-eligible renewable power projects) to instead receive--for a limited time only--a cash grant of equivalent value. These two provisions (among others) could have a significant impact on how renewable power projects are financed over the next few years. The purpose of this report is to both quantitatively and qualitatively analyze, from the project developer/owner perspective, the choice between the PTC and the ITC (or equivalent cash grant) for a number of different renewable power technologies.1 Because the two credits are structured differently, and apply in different ways to different technologies, the choice between the two lends itself to quantitative financial analysis of the conditions under which either the PTC or the ITC would, at least in theory, provide greater financial value. Qualitative considerations may be equally important, however, particularly in instances where quantitative differences are modest. This report proceeds as follows. Section 2 provides a brief summary of ARRA 2009, with some emphasis on those provisions designed to ease the liquidity crisis facing the renewable power sector. Section 3 describes the quantitative analysis methodology, as well as modeling results for wind, open-loop biomass, closed-loop biomass, geothermal, and landfill gas projects. Section 4 discusses a number of qualitative considerations that may play as important of a role as quantitative results in deciding between the PTC and the ITC (or equivalent cash grant). Section 5 concludes, and an Appendix provides supplemental tables that present quantitative analysis results conducted at different discount rates.

Switching power pulse system  

DOE Patents [OSTI]

A switching system for delivering pulses of power from a source to a load using a storage capacitor charged through a rectifier, and maintained charged to a reference voltage level by a transistor switch and voltage comparator. A thyristor is triggered to discharge the storage capacitor through a saturable reactor and fractional turn saturable transformer having a secondary to primary turn ratio N of n:l/n = n[sup 2]. The saturable reactor functions as a soaker'' while the thyristor reaches saturation, and then switches to a low impedance state. The saturable transformer functions as a switching transformer with high impedance while a load coupling capacitor charges, and then switches to a low impedance state to dump the charge of the storage capacitor into the load through the coupling capacitor. The transformer is comprised of a multilayer core having two secondary windings tightly wound and connected in parallel to add their output voltage and reduce output inductance, and a number of single turn windings connected in parallel at nodes for the primary winding, each single turn winding linking a different one of the layers of the multilayer core. The load may be comprised of a resistive beampipe for a linear particle accelerator and capacitance of a pulse forming network. To hold off discharge of the capacitance until it is fully charged, a saturable core is provided around the resistive beampipe to isolate the beampipe from the capacitance until it is fully charged. 5 figs.

Switching power pulse system  

DOE Patents [OSTI]

A switching system for delivering pulses of power from a source (10) to a load (20) using a storage capacitor (C3) charged through a rectifier (D1, D2), and maintained charged to a reference voltage level by a transistor switch (Q1) and voltage comparator (12). A thyristor (22) is triggered to discharge the storage capacitor through a saturable reactor (18) and fractional turn saturable transformer (16) having a secondary to primary turn ratio N of n:l/n=n.sup.2. The saturable reactor (18) functions as a "soaker" while the thyristor reaches saturation, and then switches to a low impedance state. The saturable transformer functions as a switching transformer with high impedance while a load coupling capacitor (C4) charges, and then switches to a low impedance state to dump the charge of the storage capacitor (C3) into the load through the coupling capacitor (C4). The transformer is comprised of a multilayer core (26) having two secondary windings (28, 30) tightly wound and connected in parallel to add their output voltage and reduce output inductance, and a number of single turn windings connected in parallel at nodes (32, 34) for the primary winding, each single turn winding linking a different one of the layers of the multilayer core. The load may be comprised of a resistive beampipe (40) for a linear particle accelerator and capacitance of a pulse forming network (42). To hold off discharge of the capacitance until it is fully charged, a saturable core (44) is provided around the resistive beampipe (40) to isolate the beampipe from the capacitance (42) until it is fully charged.

Distributed Robust Power System State Estimation  

E-Print Network [OSTI]

Deregulation of energy markets, penetration of renewables, advanced metering capabilities, and the urge for situational awareness, all call for system-wide power system state estimation (PSSE). Implementing a centralized estimator though is practically infeasible due to the complexity scale of an interconnection, the communication bottleneck in real-time monitoring, regional disclosure policies, and reliability issues. In this context, distributed PSSE methods are treated here under a unified and systematic framework. A novel algorithm is developed based on the alternating direction method of multipliers. It leverages existing PSSE solvers, respects privacy policies, exhibits low communication load, and its convergence to the centralized estimates is guaranteed even in the absence of local observability. Beyond the conventional least-squares based PSSE, the decentralized framework accommodates a robust state estimator. By exploiting interesting links to the compressive sampling advances, the latter jointly es...

Electric grid dependence on the configuration of a small-scale wind and solar power hybrid system  

Science Journals Connector (OSTI)

Results are presented from the modeling of a small-scale distributed power system containing power demands, photovoltaic arrays, small-scale wind turbines and an electric grid connection. Detailed models of the photovoltaic array and the wind turbine are briefly explained in addition to the solar and wind recourse models. A subunit is defined to consist of a power demand together with power contributors. It is shown how the grid dependency (or renewable energy contribution) is affected by the connection of subunits and according to the relationship between the power demand patterns and renewable resource patterns. The outcome from several case studies is presented using simulated power demands and renewable resources. In a scenario with subunit power demands characteristic for a large household and a small factory, it is shown that the coupling of subunits reduces annual grid power transfers by more than 10% and increases the renewable power contribution to the demand by almost 7%.

Limits to power system growth  

SciTech Connect (OSTI)

In the design of space nuclear power systems a variety of conversion techniques may be used, each with its own advantages and disadvantages. A study was performed which analyzed over 120 proposed system designs. The designs were compared to identify the optimum conversion system as a function of power level and find limits to specific mass (kg/kWe) for each power cycle. Furthermore, the component masses were studied to determine which component of the overall design contributes the most to total system mass over a variety of power levels. The results can provide a focus for future research efforts by selecting the best conversion technology for the desired power range, and optimizing the system component which contributes most to the total mass.

INTEGRATION OF RENEWABLE ENERGY SYSTEMS TO ISOLATED DESERT SITE IN EGYPT. Part I: Wind System Optimisation  

Science Journals Connector (OSTI)

ABSTRACT This paper discusses the technical and economical studies and the conceptual system designs for using renewable energy sources such as photovoltaic (PV), wind and biogas supplemented by conventional energy sources as an integerated system to isolated desert site south west of Egypt. (East Oweinat). The first part deals with the wind system optimisation . An attempt has been done, to find an analytical expression and graphical presentation for the proper tower height of a given Wind Energy Conversion System (WECS). This height is expressed as a function of both WECS characteristic speeds (Vci & Vr), and parameters of the site wind speed frequency distribution(WSFD). Application of the derived formula at different sites, and upon various WECS's shows that installing the WECS at that height ensures a high capacity factor of not less than 0.4 for the WECS. The paper also presents the possibility of determining that height directly from the given nomogram. KEY WORDS Wind system optimisation; integrated renewable energy system; wind energy conversion system; desert development; optimum height.

Assessing employment in renewable energy technologies: A case study for wind power in Brazil  

Science Journals Connector (OSTI)

Abstract Environmental concerns and the search for climate change mitigation have led to the deployment of renewable energy technologies (RET) in several countries. The adoption of incentive policies, especially those based on heavy subsides, has motivated the discussion of social and economic benefits brought about by these technologies, mainly on the impact on employment rates. In this context, several studies have been conducted to quantify job creation by RET, concluding that the latter are more labor intensive than traditional fossil fueled technologies. However, results for different assessments vary largely due to distinct methodological approaches, and are frequently highly aggregated. Thus, results are not comparable or applicable to other contexts. Previous studies have failed to quantify the effects of imports and exports of RET equipment in total employment, usually associating employment and installed capacity in the year studied. This study has aimed to address these issues, creating an index for employment quantification based on production, instead of installed, capacity. We have estimated both direct jobs in manufacture, construction, and operation and management, and indirect jobs both in the upstream supply chains of materials and inputs to manufacture of wind turbines and construction of wind farms. We have also performed an assessment of jobs created in wind energy projects which are expected to begin operation in Brazil until 2017. The resulting job potential in Brazil corresponds to13.5 persons-year equivalent for each MW installed between manufacture and first year of operation of a wind power plant, and 24.5 persons-year equivalent over the wind farm lifetime. Results show that major contribution from wind power for job creation are in the construction stage and, despite of the low amount of jobs created in operation and maintenance relative to new installed capacity, those stable jobs stand out as they persist over the entire wind farm's life time.

Integrated operation of electric vehicles and renewable generation in a smart distribution system  

Science Journals Connector (OSTI)

Abstract Distribution system complexity is increasing mainly due to technological innovation, renewable Distributed Generation (DG) and responsive loads. This complexity makes difficult the monitoring, control and operation of distribution networks for Distribution System Operators (DSOs). In order to cope with this complexity, a novel method for the integrated operational planning of a distribution system is presented in this paper. The method introduces the figure of the aggregator, conceived as an intermediate agent between end-users and DSOs. In the proposed method, energy and reserve scheduling is carried out by both aggregators and DSO. Moreover, Electric Vehicles (EVs) are considered as responsive loads that can participate in ancillary service programs by providing reserve to the system. The efficiency of the proposed method is evaluated on an 84-bus distribution test system. Simulation results show that the integrated scheduling of \\{EVs\\} and renewable generators can mitigate the negative effects related to the uncertainty of renewable generation.

Development of a general sustainability indicator for renewable energy systems: A review  

Science Journals Connector (OSTI)

Abstract Renewable energy is considered as a solution for mitigating climate change and environmental pollution; however, an important problem of the application of renewable energy systems (RESs) is that the evaluation of the sustainability of these systems is extremely complex. In order to assess the sustainability of renewable energy systems comprehensively, the use of sustainability indicators (SIs) is often necessary. Since sustainability indicators are necessary to reflect various aspects of sustainability, the development of a general sustainability indicator (GSI) including many basic sustainability indicators (BSIs) becomes critical. In this paper, the methods of selection, quantification, evaluation and weighting of the basic indicators as well as the methods of GSI aggregation are reviewed. The advantages and disadvantages of each method are discussed. Based on these discussion and the analysis of the uncertainties of sustainability assessment, an effective framework and its procedures of the development of GSI for renewable energy systems is presented. This GSI is not only able to evaluate all the sustainability criteria of RESs, but also can provide numerical results of sustainability assessment for different objective systems. The proposed framework in this study can be used as a guidance of the development of sustainability indicator for various renewable energy systems.

Design and implementation of a marine animal alert system to support Marine Renewable Energy  

SciTech Connect (OSTI)

Power extracted from fast moving tidal currents has been identified as a potential commercial-scale source of renewable energy. Device developers and utilities are pursuing deployment of prototype tidal turbines to assess technology viability, site feasibility, and environmental interactions. Deployment of prototype turbines requires permits from a range of regulatory authorities. Ensuring the safety of marine animals, particularly those under protection of the Endangered Species Act of 1973 (ESA) and the Marine Mammal Protection Act of 1972 has emerged as a key regulatory challenge for initial MHK deployments. The greatest perceived risk to marine animals is from strike by the rotating blades of tidal turbines. Development of the marine mammal alert system (MAAS) was undertaken to support monitoring and mitigation requirements for tidal turbine deployments. The prototype system development focused on Southern Resident killer whales (SRKW), an endangered population of killer whales that frequents Puget Sound and is intermittently present in the part of the sound where deployment of prototype tidal turbines is being considered. Passive acoustics were selected as the primary means because of the vocal nature of these animals. The MAAS passive acoustic system consists of two-stage process involving the use of an energy detector and a spectrogram-based classifier to distinguish between SKRWs calls and noise.

Renewable electricity policies, heterogeneity, and cost effectiveness  

Science Journals Connector (OSTI)

Abstract Renewable electricity policies promote investment in renewable electricity generators and have become increasingly common around the world. Because of intermittency and the composition of other generators in the power system, the value of certain renewable particularly wind and solar varies across locations and technologies. This paper investigates the implications of this heterogeneity for the cost effectiveness of renewable electricity policies. A simple model of the power system shows that renewable electricity policies cause different investment mixes. Policies also differ according to their effect on electricity prices, and both factors cause the cost effectiveness to vary across policies. We use a detailed, long-run planning model that accounts for intermittency on an hourly basis to compare the cost effectiveness for a range of policies and alternative parameter assumptions. The differences in cost effectiveness are economically significant, where broader policies, such as an emissions price, outperform renewable electricity policies.

In the 17 quarters of the project, we have accomplished the following milestones - first, construction of the three multiwavelength laser scattering machines for different light scattering study purposes; second, build up of simulation software package for simulation of field and laboratory particulates matters data; third, carried out field online test on exhaust from combustion engines with our laser scatter system. This report gives a summary of the results and achievements during the project's 16 quarters period. During the 16 quarters of this project, we constructed three multiwavelength scattering instruments for PM2.5 particulates. We build up a simulation software package that could automate the simulation of light scattering for different combinations of particulate matters. At the field test site with our partner, Alturdyne, Inc., we collected light scattering data for a small gas turbine engine. We also included the experimental data feedback function to the simulation software to match simulation with real field data. The PM scattering instruments developed in this project involve the development of some core hardware technologies, including fast gated CCD system, accurately triggered Passively Q-Switched diode pumped lasers, and multiwavelength beam combination system. To calibrate the scattering results for liquid samples, we also developed the calibration system which includes liquid PM generator and size sorting instrument, i.e. MOUDI. In this report, we give the concise summary report on each of these subsystems development results.

Nuclear-Renewable Hybrid System Economic Basis for Electricity, Fuel, and Hydrogen  

SciTech Connect (OSTI)

Concerns about climate change and altering the ocean chemistry are likely to limit the use of fossil fuels. That implies a transition to a low-carbon nuclear-renewable electricity grid. Historically variable electricity demand was met using fossil plants with low capital costs, high operating costs, and substantial greenhouse gas emissions. However, the most easily scalable very-low-emissions generating options, nuclear and non-dispatchable renewables (solar and wind), are capital-intensive technologies with low operating costs that should operate at full capacities to minimize costs. No combination of fully-utilized nuclear and renewables can meet the variable electricity demand. This implies large quantities of expensive excess generating capacity much of the time. In a free market this results in near-zero electricity prices at times of high nuclear renewables output and low electricity demand with electricity revenue collapse. Capital deployment efficiencythe economic benefit derived from energy systems capital investment at a societal levelstrongly favors high utilization of these capital-intensive systems, especially if low-carbon nuclear renewables are to replace fossil fuels. Hybrid energy systems are one option for better utilization of these systems that consumes excess energy at times of low prices to make some useful product.The economic basis for development of hybrid energy systems is described for a low-carbon nuclear renewable world where much of the time there are massivequantities of excess energy available from the electric sector.Examples include (1) high-temperature electrolysis to generate hydrogen for non-fossil liquid fuels, direct use as a transport fuel, metal reduction, etc. and (2) biorefineries.Nuclear energy with its concentrated constant heat output may become the enabling technology for economically-viable low-carbon electricity grids because hybrid nuclear systems may provide an economic way to produce dispatachable variable electricity with economic base-load operation of the reactor.

RLOPF (risk-limiting optimal power flow) for systems with high penetration of wind power  

Science Journals Connector (OSTI)

Abstract In this paper, we formulate a RLOPF (risk-limiting optimal power flow) problem for systems with high penetration of wind power to address the issue of possibly violating the security constraints in power systems due to the volatility of wind power generations. To cope with the computational complexity of the proposed RLOPF problem, we propose a computationally efficient RLOPF algorithm assisted by the off-line constructed probability distribution models for bus voltage magnitudes and transmission line real power flows. We apply the proposed RLOPF algorithm to the RLOPF problems on a 26-bus power system for two cases of significantly different re-dispatching percentage share for non-renewable power generations to compensate the volatility of wind power generations. The test results reveal that the performance of all solutions obtained by the proposed RLOPF algorithm of various step-sizes in both cases meet the required probability 0.95 on satisfying the security constraints in the presence of variable wind power generations, and the CPU time consumption are mostly within 1s. We also test the performance of conventional OPF (optimal power flow) solution on both cases, and the resulted probability are all smaller than 0.783. These test results demonstrate the merit and the computational efficiency of the proposed RLOPF algorithm.

Effective Ancillary Services Market Designs on High Wind Power Penetration Systems: Preprint  

SciTech Connect (OSTI)

This paper focuses on how the ancillary service market designs are implemented and how they may require changes on systems with greater penetrations of variable renewable energy suppliers, in particular wind power. Ancillary services markets have been developed in many of the restructured power system regions throughout the world. Ancillary services include the services that support the provision of energy to support power system reliability. The ancillary services markets are tied tightly to the design of the energy market and to the physics of the system and therefore careful consideration of power system economics and engineering must be considered in their design. This paper focuses on how the ancillary service market designs are implemented and how they may require changes on systems with greater penetrations of variable renewable energy suppliers, in particular wind power.

A practical and accurate method of modeling various transformers in power systems using a general circuit model approach is described in this paper. The advantage of the new approach is that it can model transformers along with a complex circuit network, while avoiding the use of symmetrical components, unlike other approaches. The transformer modeling technique introduced in this paper is very useful to accurately determine fault current distribution in a power system and electromagnetic interference on pipelines and communication lines installed in a right-of-way consisting of transmission lines operating at different voltages.

Sustainable feasibility of solar photovoltaic powered street lighting systems  

Science Journals Connector (OSTI)

Abstract In the last few years, due to soaring fuel prices and gas emissions, renewable energy technologies have been suggested as the power source for infrastructures. The interest in solar photovoltaic (PV) assisted street lighting systems stems from the fact that they are sustainable and environmentally friendly compared to conventional energy powered systems. The present paper investigates and compares the economic feasibility of two types of systems: islanded and grid-connected system, for the street lighting systems in Hunan Province, China. Based on two options of solar panel materials, a simulation model of the system is developed for economic, technical and environmental feasibility. The comprehensively sustainability feasibility of these systems is conducted taking into account the cost, energy generation, CO2 emissions and renewable fraction. Radar plot is employed to integrate all the sustainability indicators into a general indicator, which presents systems sustainability as a real number in the interval [0,2]. Results show that for street lighting systems of all the cities, single crystal panel has a larger number of annual electricity generation, less emissions and higher environmental performance, but is more expansive than polycrystalline. It is also found that when the feed-in tariff higher than 1.27CNY/kWh, the cost of energy (COE) of the solar powered lighting systems is less than a pure grid powered system. This will incite the use of solar PV in infrastructures. Through comparing the scores of sustainability, it is found that the Loudi system has the highest feasibility while the Yongzhou system has the lowest in the province.

Regulatory analysis for amendments to regulations for the environmental review for renewal of nuclear power plant operating licenses. Final report  

SciTech Connect (OSTI)

This regulatory analysis provides the supporting information for a proposed rule that will amend the Nuclear Regulatory Commission`s environmental review requirements for applications for renewal of nuclear power plant operating licenses. The objective of the proposed rulemaking is to improve regulatory efficiency by providing for the generic evaluation of certain environmental impacts associated with nuclear plant license renewal. After considering various options, the staff identified and analyzed two major alternatives. With Alternative A, the existing regulations would not be amended. This option requires that environmental reviews be performed under the existing regulations. Alternative B is to assess, on a generic basis, the environmental impacts of renewing the operating license of individual nuclear power plants, and define the issues that will need to be further analyzed on a case-by-case basis. In addition, Alternative B removes from NRC`s review certain economics-related issues. The findings of this assessment are to be codified in 10 CFR 51. The staff has selected Alternative B as the preferred alternative.

Innovative Power?Augmentation?Guide?Vane Design of Wind?Solar Hybrid Renewable Energy Harvester for Urban High Rise Application  

Science Journals Connector (OSTI)

To generate greater quantities of energy from wind the most efficient solution would be by increasing the wind speed. Also due to the decreasing number of economic wind energy sites there are plans to place wind turbines closer to populated areas. To site wind turbines out from rural areas the current problems of wind turbines need to be resolved especially visual impact poor starting behaviour in low wind speeds noise and danger caused by blade failure. In this paper a patented wind?solar hybrid renewable energy harvester is introduced. It is a compact system that integrates and optimizes several green elements and can be built on the top (or between upper levels) of high rise buildings or structures. This system can be used in remote and urban areas particularly at locations where the wind speed is lower and more turbulent. It overcomes the inferior aspect on the low wind speed by guiding and increasing the speed of the high altitude free?stream wind through fixed or yaw?able power?augmentation?guide?vane (PAGV) before entering the wind turbine (straight?bladed vertical axis wind turbine VAWT in this project) at center portion. PAGV is a new and innovative design where its appearance or outer design can be blended into the building architecture without negative visual impact. From the studies it is shown that the wind speed increment in the PAGV can be produced according to the Bernoullis principle. Computational fluid dynamics (CFD) simulation is used to optimize the geometry of the PAGV and the simulation results demonstrated the technical possibility of this innovative concept. The PAGV replaces the free air?stream from wind by multiple channels of speed?increased and directional?controlled air?stream. With the PAGV this lift?type VAWT can be self?started and its size can be reduced for a given power output. The design is also safer since the VAWT is enclosed by the PAGV. By integrating the PAGV with the VAWT (the diameter and height of PAGV are 2 times larger than the VAWTs) the predicted power generated (at free?stream wind speed ?=?3.5? m / s ) is 1.25 times higher than the VAWT that has the same size as the PAGV. This new wind energy generation configuration should generate interest in the international market even for regions with weaker winds. The correlation between CFD simulation and wind tunnel test will be carried out and reported elsewhere.

Supporting Solar Power in Renewables Portfolio Standards: Experience from the United States  

SciTech Connect (OSTI)

Among the available options for encouraging the increased deployment of renewable electricity, renewables portfolio standards (RPS) have become increasingly popular. The RPS is a relatively new policy mechanism, however, and experience with its use is only beginning to emerge. One key concern that has been voiced is whether RPS policies will offer adequate support to a wide range of renewable energy technologies and applications or whether, alternatively, RPS programs will favor a small number of the currently least-cost forms of renewable energy. This report documents the design of and early experience with state-level RPS programs in the United States that have been specifically tailored to encourage a wider diversity of renewable energy technologies, and solar energy in particular. As shown here, state-level RPS programs specifically designed to support solar have already proven to be an important, albeit somewhat modest, driver for solar energy deployment, and those impacts are projected to continue to build in the coming years. State experience in supporting solar energy with RPS programs is mixed, however, and full compliance with existing requirements has not been achieved. The comparative experiences described herein highlight the opportunities and challenges of applying an RPS to specifically support solar energy, as well as the importance of policy design details to ensuring that program goals are achieved.

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.

Contracting Issues with Renewable Electricity Contracting Issues with Renewable Electricity Contracting Issues with Renewable Electricity October 16, 2013 - 5:08pm Addthis For many Federal agencies integrating renewable energy into a construction project, the technical and contracting issues associated with generating power at the facility are new. This page summarizes the various contracting issues that result from having on-site power generation that is actively interconnected with the power grid instead of using only a back-up generator. Many of these agreements depend on the ownership structure of the renewable energy system. Common agreements associated with a renewable electricity-generation facility include: An interconnection agreement covers the safe connection of the system to the power grid, including provisions for safe design, connection,

Broader source: Energy.gov (indexed) [DOE]

Thermal Storage System Basics Thermal Storage System Basics Concentrating Solar Power Thermal Storage System Basics August 21, 2013 - 10:33am Addthis One challenge facing the widespread use of solar energy is reduced or curtailed energy production when the sun sets or is blocked by clouds. Thermal energy storage provides a workable solution to this challenge. In a concentrating solar power (CSP) system, the sun's rays are reflected onto a receiver, which creates heat that is used to generate electricity. If the receiver contains oil or molten salt as the heat-transfer medium, then the thermal energy can be stored for later use. This enables CSP systems to be cost-competitive options for providing clean, renewable energy. Several thermal energy storage technologies have been tested and

Geothermal resources-the steam and water that lie below the earth's surface-have the Geothermal resources-the steam and water that lie below the earth's surface-have the potential to supply vast amounts of clean energy. But continuing to produce geothermal power efficiently and inexpensively can require innovative adjustments to the technology used to process it. Located in the Mayacamas Mountains of northern California, The Geysers is the world's larg- est geothermal complex. Encompassing 45 square miles along the Sonoma and Lake County border, the complex harnesses natural steam reservoirs to create clean renewable energy that accounts for one-fifth of the green power produced in California. In the late 1990s, the pressure of geothermal steam at The Geysers was falling, reducing the output of its power plants. NREL teamed with Pacific

Uses Computing Power to Uses Computing Power to Investigate Tidal Power Researchers at the National Renewable Energy Laboratory (NREL) have applied their knowledge of wind flow and turbulence to simulations of underwater tidal turbines. Inspired by similar simulations of wind turbine arrays, NREL researchers used their wind expertise, a supercomputer, and large-eddy simulation to study how the placement of turbines affects the power production of an underwater tidal turbine array. As tides ebb and flow, they create water currents that carry a significant amount of kinetic energy. To capture this energy, several companies are developing and deploying devices known as horizontal-axis tidal turbines, which resemble small wind turbines. These devices can be arranged in an array of multiple turbines to maximize the energy extracted in tidal

The market value of variable renewables: The effect of solar wind power variability on their relative price  

Science Journals Connector (OSTI)

Abstract This paper provides a comprehensive discussion of the market value of variable renewable energy (VRE). The inherent variability of wind speeds and solar radiation affects the price that VRE generators receive on the market (market value). During windy and sunny times the additional electricity supply reduces the prices. Because the drop is larger with more installed capacity, the market value of VRE falls with higher penetration rate. This study aims to develop a better understanding on how the market value with penetration, and how policies and prices affect the market value. Quantitative evidence is derived from a review of published studies, regression analysis of market data, and the calibrated model of the European electricity market EMMA. We find the value of wind power to fall from 110% of the average power price to 5080% as wind penetration increases from zero to 30% of total electricity consumption. For solar power, similarly low value levels are reached already at 15% penetration. Hence, competitive large-scale renewable deployment will be more difficult to accomplish than as many anticipate.

Optimum use of renewable energy resources to generate electricity via hybrid system  

Science Journals Connector (OSTI)

The necessity of hybrid energy system is gaining more importance day by day as it incorporates two or more than two renewable energy resources that when integrated overcome limitations inherent in either. Hybrid energy system has been seen as an excellent solution for electrification of rural place where the grid extension is difficult and economically not feasible. Such system may consist of several renewable resources such as solar PV, wind, biomass, micro-hydro, geothermal and other conventional generator for back-up where the deficiency of one system can be compensated by others. This paper depicts the different system components and their optimal combination for the efficient generation of electrical energy exploiting locally available resources. The model discussed in paper compromises of micro-hydro, solar PV and biomass for the rural village in Nepal known as Kalikhola which is used as a case study. The optimised hybrid system shows a unit cost of $0.088/KWh which is obtained after the simulation considering contribution of individual renewable resources participating in the system.

Thermo-economic assessment of end user value in home and community scale renewable energy systems  

Science Journals Connector (OSTI)

This study employs thermo-economic analysis to establish a homeowner-centric valuation of renewable energy technologies. The evaluation methodology is illustrated using several classes of renewable energy technology including ground-source heat pumps wind turbines photovoltaic panels and solar thermal water heaters. Energy systems employing each of these technologies are examined when servicing the typical domestic energy loads of a single-detached home. Through the analysis it is learned that single-home photovoltaic systems produce energy at an annual cost approximately four times that of grid electricity while wind energy systems deliver this energy at approximately twice the cost of grid electricity. Further single-detached homeowners currently heating with fuel oil and/or grid electricity may expect to save between $1000 and $1800 per year when switching to a ground-source heat pump system; whereas those considering the implementation of a solar thermal water heater can expect to spend an additional $245 per year for hot water. Investigation of larger scale renewable systems examined the performance of wind turbines and ground-source heat pumps when serving groups of single-detached homes; wind turbines were found to exhibit significant economies of scale.

Emergence of energy storage technologies as the solution for reliable operation of smart power systems: A review  

Science Journals Connector (OSTI)

Abstract The ever increasing penetration of renewable energy systems (RESs) in today deregulated intelligent power grids, necessitates the use of electrical storage systems. Energy storage systems (ESSs) are helpful to make balance between generation and demand improving the performance of whole power grid. In collaboration with RESs, energy storage devices can be integrated into the power networks to bring ancillary service for the power system and hence enable an increased penetration of distributed generation (DG) units. This paper presents different applications of electrical energy storage technologies in power systems emphasizing on the collaboration of such entities with RESs. The role of \\{ESSs\\} in intelligent micropower grids is also discussed where the stochastic nature of renewable energy sources may affect the power quality. Particular attention is paid to flywheel storage, electrochemical storage, pumped hydroelectric storage, and compressed air storage and their operating principle are discussed as well. The application of each type in the area of power system is investigated and compared to others.

The report catalogues and describes modeling assumptions, computational methodologies, data inputs, and parameter estimation techniques. A number of offline analyses used in lieu of RFM modeling components are also described. The RFM consists of six analytical submodules that represent each of the major renewable energy resources--wood, municipal solid waste (MSW), solar energy, wind energy, geothermal energy, and alcohol fuels. The RFM also reads in hydroelectric facility capacities and capacity factors from a data file for use by the NEMS Electricity Market Module (EMM). The purpose of the RFM is to define the technological, cost and resource size characteristics of renewable energy technologies. These characteristics are used to compute a levelized cost to be competed against other similarly derived costs from other energy sources and technologies. The competition of these energy sources over the NEMS time horizon determines the market penetration of these renewable energy technologies. The characteristics include available energy capacity, capital costs, fixed operating costs, variable operating costs, capacity factor, heat rate, construction lead time, and fuel product price.

Life-cycle analysis results for geothermal systems in comparison to other power systems: Part II.  

SciTech Connect (OSTI)

A study has been conducted on the material demand and life-cycle energy and emissions performance of power-generating technologies in addition to those reported in Part I of this series. The additional technologies included concentrated solar power, integrated gasification combined cycle, and a fossil/renewable (termed hybrid) geothermal technology, more specifically, co-produced gas and electric power plants from geo-pressured gas and electric (GPGE) sites. For the latter, two cases were considered: gas and electricity export and electricity-only export. Also modeled were cement, steel and diesel fuel requirements for drilling geothermal wells as a function of well depth. The impact of the construction activities in the building of plants was also estimated. The results of this study are consistent with previously reported trends found in Part I of this series. Among all the technologies consider
