National Offshore Wind Energy Grid Interconnection Study  

SciTech Connect (OSTI)

The National Offshore Wind Energy Grid Interconnection Study (NOWEGIS) considers the availability and potential impacts of interconnecting large amounts of offshore wind energy into the transmission system of the lower 48 contiguous United States. A total of 54GW of offshore wind was assumed to be the target for the analyses conducted. A variety of issues are considered including: the anticipated staging of offshore wind; the offshore wind resource availability; offshore wind energy power production profiles; offshore wind variability; present and potential technologies for collection and delivery of offshore wind energy to the onshore grid; potential impacts to existing utility systems most likely to receive large amounts of offshore wind; and regulatory influences on offshore wind development. The technologies considered the reliability of various high-voltage ac (HVAC) and high-voltage dc (HVDC) technology options and configurations. The utility system impacts of GW-scale integration of offshore wind are considered from an operational steady-state perspective and from a regional and national production cost perspective.

Grid Interconnection and Performance Testing Procedures for Vehicle-To-Grid (V2G) Power Electronics: Preprint  

SciTech Connect (OSTI)

Bidirectional power electronics can add vehicle-to-grid (V2G) capability in a plug-in vehicle, which then allows the vehicle to operate as a distributed resource (DR). The uniqueness of the battery-based V2G power electronics requires a test procedure that will not only maintain IEEE interconnection standards, but can also evaluate the electrical performance of the vehicle working as a DR. The objective of this paper is to discuss a recently published NREL technical report that provides interim test procedures for V2G vehicles for their integration into the electrical distribution systems and for their performance in terms of continuous output power, efficiency, and losses. Additionally, some other test procedures are discussed that are applicable to a V2G vehicle that desires to provide power reserve functions. A few sample test results are provided based on testing of prototype V2G vehicles at NREL.

Interconnecting PV on New York City's Secondary Network Distribution System  

SciTech Connect (OSTI)

The U.S. Department of Energy (DOE) has teamed with cities across the country through the Solar America Cities (SAC) partnership program to help reduce barriers and accelerate implementation of solar energy. The New York City SAC team is a partnership between the City University of New York (CUNY), the New York City Mayor s Office of Long-term Planning and Sustainability, and the New York City Economic Development Corporation (NYCEDC).The New York City SAC team is working with DOE s National Renewable Energy Laboratory (NREL) and Con Edison, the local utility, to develop a roadmap for photovoltaic (PV) installations in the five boroughs. The city set a goal to increase its installed PV capacity from1.1 MW in 2005 to 8.1 MW by 2015 (the maximum allowed in 2005). A key barrier to reaching this goal, however, is the complexity of the interconnection process with the local utility. Unique challenges are associated with connecting distributed PV systems to secondary network distribution systems (simplified to ???¢????????networks???¢??????? in this report). Although most areas of the country use simpler radial distribution systems to distribute electricity, larger metropolitan areas like New York City typically use networks to increase reliability in large load centers. Unlike the radial distribution system, where each customer receives power through a single line, a network uses a grid of interconnected lines to deliver power to each customer through several parallel circuits and sources. This redundancy improves reliability, but it also requires more complicated coordination and protection schemes that can be disrupted by energy exported from distributed PV systems. Currently, Con Edison studies each potential PV system in New York City to evaluate the system s impact on the network, but this is time consuming for utility engineers and may delay the customer s project or add cost for larger installations. City leaders would like to streamline this process to facilitate faster, simpler, and less expensive distributed PV system interconnections. To assess ways to improve the interconnection process, NREL conducted a four-part study with support from DOE. The NREL team then compiled the final reports from each study into this report. In Section 1???¢????????PV Deployment Analysis for New York City???¢????????we analyze the technical potential for rooftop PV systems in the city. This analysis evaluates potential PV power production in ten Con Edison networks of various locations and building densities (ranging from high density apartments to lower density single family homes). Next, we compare the potential power production to network loads to determine where and when PV generation is most likely to exceed network load and disrupt network protection schemes. The results of this analysis may assist Con Edison in evaluating future PV interconnection applications and in planning future network protection system upgrades. This analysis may also assist other utilities interconnecting PV systems to networks by defining a method for assessing the technical potential of PV in the network and its impact on network loads. Section 2???¢????????A Briefing for Policy Makers on Connecting PV to a Network Grid???¢????????presents an overview intended for nontechnical stakeholders. This section describes the issues associated with interconnecting PV systems to networks, along with possible solutions.

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.

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.

IRSP (integrated resource strategic planning) with interconnected smart grids in integrating renewable energy and implementing DSM (demand side management) in China  

Science Journals Connector (OSTI)

Abstract The China's electricity consumption was 4966TWh in 2012, which is the world top electricity consumer. The low carbon electricity is one of the key issues of its sustainable development. IRSP (integrated resource strategic planning) is a useful tool to implement DSM (demand side management) and power planning on the supply side. However, the role of interconnected smart grids with fast growing cross-region transmission is not considered in the IRSP. Therefore, the paper proposes the model of IRSP with interconnected smart grids to integrate more renewable power generation to the grids and implement more DSM projects, which is called as IRSP-sgs (IRSP smart grids) model. Two scenarios are projected to study the impact of cross-region transmission on low carbon electricity by using the IRSP-sgs model until 2025 in China. Results show that the scenario with enhanced cross-region transmission helps to reduce electricity generation by 784.38TWh and reduce CO2 emission by 999.57 million tons during 20132025, since the multi-regional power operation can integrate more than 488.30TWh renewable generation into the grids and implement more DSM projects to substitute generation. In addition, it also provides tremendous opportunities to improve the stable operation of the power system.

Performance testing of small interconnected wind systems  

SciTech Connect (OSTI)

There is a need for performance information on small windmills intended for interconnected operation with utility distribution service. The owner or prospective buyer needs the data to estimate economic viability and service reliability, while the utility needs it to determine interconnection arrangements, maintain quality of power delivered by its line, and to answer customer inquiries. No existing testing program provides all the information needed, although the Rocky Flats test site comes close. To fill this need for Michigan, Consumers Power Company and the Michigan Electric Cooperative Association helped support a two-year program at Michigan State University involving extensive performance testing of an Enertech 1500 and a 4-kW Dakota with a Gemini inverter. The performance study suggested measurements necessary to characterize SWECS for interconnected operation. They include SWECS energy output to a-c line, miles of wind passing the rotor, var-hour metering for average var consumption, and recording watt, current, and voltmeters to assess SWECS output variability. Added instruments for waveform measurement (to assess power quality) are also needed. Typical data taken at the MSU test site are used to illustrate the techniques and preliminary data from a current project is given. Finally, conclusions about SWECS performance are listed.

Reliability assessment of autonomous power systems incorporating HVDC interconnection links  

SciTech Connect (OSTI)

The objective of this paper is to present an improved computational method for the overall reliability assessment of autonomous power systems that may or may not contain HVdc interconnection links. This is a hybrid method based on a Monte-Carlo simulation sequential approach which incorporates an analytical approach for the reliability modeling of the HVdc transmission links. The developed models and techniques have been implemented into a computer program that can be used to simulate the operational practices and characteristics of the overall system under study efficiently and realistically. A set of reliability indices are calculated for each load-point of interest and the entire system while a set of additional indices is calculated for quantifying the reliability performance of the interconnection links under the specified operating requirements. The analysis of a practical system is also included for a number of studies representing its various operating and design characteristics.

Comparing Germany's and California's Interconnection Processes for PV Systems (White Paper)  

SciTech Connect (OSTI)

Establishing interconnection to the grid is a recognized barrier to the deployment of distributed energy generation. This report compares interconnection processes for photovoltaic projects in California and Germany. This report summarizes the steps of the interconnection process for developers and utilities, the average length of time utilities take to process applications, and paperwork required of project developers. Based on a review of the available literature, this report finds that while the interconnection procedures and timelines are similar in California and Germany, differences in the legal and regulatory frameworks are substantial.

Updating Technical Screens for PV Interconnection: Preprint  

SciTech Connect (OSTI)

Solar photovoltaics (PV) is the dominant type of distributed generation (DG) technology interconnected to electric distribution systems in the United States, and deployment of PV systems continues to increase rapidly. Considering the rapid growth and widespread deployment of PV systems in United States electric distribution grids, it is important that interconnection procedures be as streamlined as possible to avoid unnecessary interconnection studies, costs, and delays. Because many PV interconnection applications involve high penetration scenarios, the process needs to allow for a sufficiently rigorous technical evaluation to identify and address possible system impacts. Existing interconnection procedures are designed to balance the need for efficiency and technical rigor for all DG. However, there is an implicit expectation that those procedures will be updated over time in order to remain relevant with respect to evolving standards, technology, and practical experience. Modifications to interconnection screens and procedures must focus on maintaining or improving safety and reliability, as well as accurately allocating costs and improving expediency of the interconnection process. This paper evaluates the origins and usefulness of the capacity penetration screen, offers potential short-term solutions which could effectively allow fast-track interconnection to many PV system applications, and considers longer-term solutions for increasing PV deployment levels in a safe and reliable manner while reducing or eliminating the emphasis on the penetration screen.

Performance of a Dynamically Controlled Inverter in a Photovoltaic System Interconnected with a Secondary Network Distribution System  

SciTech Connect (OSTI)

In 2008, a 300 kW{sub peak} photovoltaic (PV) system was installed on the rooftop of the Colorado Convention Center (CCC). The installation was unique for the electric utility, Xcel Energy, as it had not previously permitted a PV system to be interconnected on a building served by the local secondary network distribution system (network). The PV system was installed with several provisions; one to prevent reverse power flow, another called a dynamically controlled inverter (DCI), that curtails the output of the PV inverters to maintain an amount of load supplied by Xcel Energy at the CCC. The DCI system utilizes current transformers (CTs) to sense power flow to insure that a minimum threshold is maintained from Xcel Energy through the network transformers. The inverters are set to track the load on each of the three phases and curtail power from the PV system when the generated PV system current reaches 95% of the current on any phase. This is achieved by the DCI, which gathers inputs from current transformers measuring the current from the PV array, Xcel, and the spot network load. Preventing reverse power flow is a critical technical requirement for the spot network which serve this part of the CCC. The PV system was designed with the expectation that the DCI system would not curtail the PV system, as the expected minimum load consumption was historically higher than the designed PV system size. However, the DCI system has operated many days during the course of a year, and the performance has been excellent. The DCI system at the CCC was installed as a secondary measure to insure that a minimum level of power flows to the CCC from the Xcel Energy network. While this DCI system was intended for localized control, the system could also reduce output percent if an external smart grid control signal was employed. This paper specifically focuses on the performance of the innovative design at this installation; however, the DCI system could also be used for new s- art grid-enabled distribution systems where renewables power contributions at certain conditions or times may need to be curtailed.

Viscosity Solutions of Systems of PDEs with Interconnected Obstacles and Switching Problem  

SciTech Connect (OSTI)

This paper deals with existence and uniqueness of a solution in viscosity sense, for a system of m variational partial differential inequalities with inter-connected obstacles. A particular case is the Hamilton-Jacobi-Bellmann system of the Markovian stochastic optimal m-states switching problem. The switching cost functions depend on (t,x). The main tool is the notion of systems of reflected backward stochastic differential equations with oblique reflection.

Phase 1 - Evaluation of a Functional Interconnect System for Solid Oxide Fuel Cells  

SciTech Connect (OSTI)

This project is focused on evaluating the suitability of materials and complex multi-materials systems for use as solid oxide fuel cell interconnects. ATI Allegheny Ludlum has generated promising results for interconnect materials which incorporate modified surfaces. Methods for producing these surfaces include cladding, which permits the use of novel materials, and modifications via unique thermomechanical processing, which allows for the modification of materials chemistry. The University of Pittsburgh is assisting in this effort by providing use of their in-place facilities for dual atmosphere testing and ASR measurements, along with substantial work to characterize post-exposure specimens. Carnegie Mellon is testing interconnects for chromia scale spallation resistance using macro-scale and nano-scale indentation tests. Chromia spallation can increase electrical resistance to unacceptable levels and interconnect systems must be developed that will not experience spallation within 40,000 hours at operating temperatures. Spallation is one of three interconnect failure mechanisms, the others being excessive growth of the chromia scale (increasing electrical resistance) and scale evaporation (which can poison the cathode). The goal of indentation fracture testing at Carnegie Mellon is to accelerate the evaluation of new interconnect systems (by inducing spalls at after short exposure times) and to use fracture mechanics to understand mechanisms leading to premature interconnect failure by spallation. Tests include bare alloys from ATI and coated systems from DOE Laboratories and industrial partners, using ATI alloy substrates. West Virginia University is working towards developing a cost-effective material for use as a contact material in the cathode chamber of the SOFC. Currently materials such as platinum are well suited for this purpose, but are cost-prohibitive. For the solid-oxide fuel cell to become a commercial reality it is imperative that lower cost components be developed. Based on the results obtained to date, it appears that sterling silver could be an inexpensive, dependable candidate for use as a contacting material in the cathode chamber of the solid-oxide fuel cell. Although data regarding pure silver samples show a lower rate of thickness reduction, the much lower cost of sterling silver makes it an attractive alternative for use in SOFC operation.

Automated Grid Disruption Response System: Robust Adaptive Topology Control (RATC)  

SciTech Connect (OSTI)

GENI Project: The RATC research team is using topology control as a mechanism to improve system operations and manage disruptions within the electric grid. The grid is subject to interruption from cascading faults caused by extreme operating conditions, malicious external attacks, and intermittent electricity generation from renewable energy sources. The RATC system is capable of detecting, classifying, and responding to grid disturbances by reconfiguring the grid in order to maintain economically efficient operations while guaranteeing reliability. The RATC system would help prevent future power outages, which account for roughly $80 billion in losses for businesses and consumers each year. Minimizing the time it takes for the grid to respond to expensive interruptions will also make it easier to integrate intermittent renewable energy sources into the grid.

Feasibility studies of a power interconnection system for Central American countries: SIEPAC project  

SciTech Connect (OSTI)

The electrical systems of the Central American countries are linked by 230 kV ac weak border interconnections forming two separated subsystems. The first one includes Guatemala and El Salvador, and the other one comprises the systems of Honduras, Nicaragua, Costa Rica, and Panama. As a consequence, unrestricted energy exchanges among all countries are not possible. This article describes the SIEPAC project which consists of a 1,678 km long 500 kV ac power transmission line that would link the six electrical systems of the region through seven power substations (one for each country and two in Panama), installed close to the highest demand national centers and six control centers of energy (one for each country) to allow coordinated operation of the interconnection.This project also considers a set of complementary assets (230 ac power transmission lines into some countries and the border transmission line between El Salvador and Honduras, and various other equipment). The power transmission line will greatly reinforce the actual border interconnections, which have a reduced capacity of exchange and technical problems associated with the stability of a weak longitudinal system. On the other hand, economic savings for the region would be achieved, coming from a higher coordination level in the operation and planning of their systems.

Abstract The integration of variable energy sources in weak power grids poses many technical and economic challenges. Both aspects have an impact on the development of grid codes, that is worth analysing. Grid codes shall be adapted to technical constraints in the corresponding power grid, such as the network strength and the characteristics of generation technologies. This paper reviews and compares technical requirements imposed on to generation assets in countries with very distinct characteristics, in order to analyse the influence of weakness and isolation of a power grid on the interconnection conditions imposed by system operators to grid users. Current and future regulation aspects are covered.

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.

Performance-aware Energy Saving Mechanism in Interconnection Networks for Parallel Systems  

Science Journals Connector (OSTI)

Abstract The growing processing power of parallel computing systems require interconnection networks a higher level of complexity and higher performance, thus consuming more energy. Link components contributes a substantial proportion of the total energy consumption of the networks. Many researchers have proposed approaches to judiciously change the link speed as a function of traffic to save energy when the traffic is light. However, the link speed reduction incurs an increase in average packet latency, thus degrades network performance. This paper addresses that issue with a performance-aware energy saving mechanism. The simulation results show that the proposed mechanism outperforms the energy saving mechanisms in literature.

Security services architecture for Secure Mobile Grid Systems  

Science Journals Connector (OSTI)

Mobile Grid, is a full inheritor of the Grid with the additional feature that it supports mobile users and resources. Security is an important aspect in Grid based systems, and it is more complex to ensure this in a mobile platform owing to the limitations of resources in these devices. A Grid infrastructure that supports the participation of mobile nodes and incorporates security aspects will thus play a significant role in the development of Grid computing. The idea of developing software through systematic development processes to improve software quality is not new. However, many information systems such as those of Grid Computing are still not developed through methodologies which have been adapted to their most differentiating features. The lack of adequate development methods for this kind of systems in which security is taken into account has encouraged us to build a methodology to develop them, offering a detailed guide for their analysis, design and implementation. It is important to use software V&V techniques, according to IEEE Std. 1012 for Software Verification and Validation, to ensure that a software system meets the operational needs of the user. This ensures that the requirements for the system are correct, complete, and consistent, and that the life-cycle products correctly design and implement system requirements. This paper shows part of a development process that we are elaborating for the construction of information systems based on Grid Computing, which are highly dependent on mobile devices in which security plays a highly important role. In the design activity of the process, we design a security architecture which serves as a reference for any mobile Grid application that we wish to build since this security architecture defines a complete set of security services which will be instantiated depending on the requirements and features found in previous activities of the process. A V&V task is also defined in the design activity to validate and verify both the architecture built and the traceability of the artifacts generated in this activity. In this paper, we will present the service-oriented security architecture for Mobile Grid Systems which considers all possible security services that may be required for any mobile Grid application.

Electric network interconnection of Mashreq Arab Countries  

SciTech Connect (OSTI)

Power system interconnection is a well established practice for a variety of technical and economical reasons. Several interconnected networks exist worldwide for a number of factors. Some of these networks cross international boundaries. This presentation discusses the future developments of the power systems of Mashreq Arab Countries (MAC). MAC consists of Bahrain, Egypt, Iraq, Jordan, Kuwait, Lebanon, Oman, Qatar, Saudi Arabia, United Arab Emirates (UAE), and Yemen. Mac power systems are operated by government or semigovernment bodies. Many of these countries have national or regional electric grids but are generally isolated from each other. With the exception of Saudi Arabia power systems, which employ 60 Hz, all other MAC utilities use 50 Hz frequency. Each country is served by one utility, except Saudi Arabia, which is served by four major utilities and some smaller utilities serving remote towns and small load centers. The major utilities are the Saudi Consolidated electric Company in the Eastern Province (SCECO East), SCECO Center, SCECO West, and SCECO South. These are the ones considered in this study. The energy resources in MAC are varied. Countries such as Egypt, Iraq, and Syria have significant hydro resources.The gulf countries and Iraq have abundant fossil fuel, The variation in energy resources as well as the characteristics of the electric load make it essential to look into interconnections beyond the national boundaries. Most of the existing or planned interconnections involve few power systems. A study involving 12 countries and over 20 utilities with different characteristics represents a very large scale undertaking.

Initial Studies on Actionable Control for Improving Small Signal Stability in Interconnected Power Systems  

SciTech Connect (OSTI)

Power consumption and demand continues to grow around the world. As the electric power grid continues to be put under more stress, the conditions of instability are more likely to occur. One cause of such instabilities is intearea oscillations, such as the oscillation that resulted in the August 10, 1996 blackout of the WECC. This paper explores different potential operations of different devices on the power system to improve the damping of these interarea oscillations using two different simulation models

Ontology matching system for future energy smart grids  

Science Journals Connector (OSTI)

Abstract Future power systems (commonly referred to as Smart Grids) will be managed by numerous intelligent electronic devices. These devices will have to interoperate; that is, they will need to exchange data with each other in order to co-operate over complex control tasks. Interoperability will only be achieved when Smart Grid devices share common semantics on the data they exchange. Standardization bodies have created standard data models defining these common semantics, but a unified standard data model has not been created for all Smart Grids. Consequently, in order to achieve interoperability in this domain, it is mandatory to find semantic correspondences (alignments) between different standard data models. Creating equivalent ontologies from the standard data models facilitates this task, because ontologies provide powerful reasoning services that can be used for automating ontology aligning. The majority of ontology matchers proposed in the state of the art, however, are only able to find simple equivalences of terms, while most alignments in Smart Grids are complex correspondences involving more than two terms. This paper presents an innovative ontology matching system that finds complex correspondences by processing expert knowledge from external domain ontologies and by using novel matching methods. The tests carried out in this study were based on the main interoperability issue within Smart Grids: interactions between CIM and SCL data models. In such tests, the proposed system outperformed one of the best ontology matchers according to the Ontology Alignment Evaluation Initiative (OAEI).

POWER GRID DYNAMICS: ENHANCING POWER SYSTEM OPERATION THROUGH PRONY ANALYSIS  

SciTech Connect (OSTI)

Prony Analysis is a technique used to decompose a signal into a series consisting of weighted complex exponentials and promises to be an effi cient way of recognizing sensitive lines during faults in power systems such as the U.S. Power grid. Positive Sequence Load Flow (PSLF) was used to simulate the performance of a simple two-area-four-generator system and the reaction of the system during a line fault. The Dynamic System Identifi cation (DSI) Toolbox was used to perform Prony analysis and use modal information to identify key transmission lines for power fl ow adjustment to improve system damping. The success of the application of Prony analysis methods to the data obtained from PSLF is reported, and the key transmission line for adjustment is identifi ed. Future work will focus on larger systems and improving the current algorithms to deal with networks such as large portions of the Western Electricity Coordinating Council (WECC) power grid.

The power supply effects before and after using the power grid interlink and EMS control are contrasted. Their application has improved the power supply reliability, boosted up the ability against impacts, decreased the spare capability of generators, reduced the maintenance work, and saved the investment.

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.

Description Hopper's compute nodes are connected via a custom high-bandwidth, low-latency network provided by Cray. The connectivity is in the form of a "mesh" in which each node is connected to other nearby nodes like strands in a fishing net, except that the mesh extends in three dimensions. Each network node handles not only data destined for itself, but also data to be relayed to other nodes. Nodes at the "edges" of the mesh network are connected to nodes at the other edge to form a 3-D torus. The custom chips that route communication over the network are known as "Gemini" and the entire network is often referred to as the "Cray Gemini

Data Management and Analysis for the Earth System Grid  

SciTech Connect (OSTI)

The international climate community is expected to generate hundreds of petabytes of simulation data within the next five to seven years. This data must be accessed and analyzed by thousands of analysts worldwide in order to provide accurate and timely estimates of the likely impact of climate change on physical, biological, and human systems. Climate change is thus not only a scientific challenge of the first order but also a major technological challenge. To address this technological challenge, the Earth System Grid Center for Enabling Technologies (ESG-CET) has been established within the U.S. Department of Energy's Scientific Discovery through Advanced Computing (SciDAC)-2 program, with support from the offices of Advanced Scientific Computing Research and Biological and Environmental Research. ESG-CET's mission is to provide climate researchers worldwide with access to the data, information, models, analysis tools, and computational capabilities required to make sense of enormous climate simulation datasets. Its specific goals are to (1) make data more useful to climate researchers by developing Grid technology that enhances data usability; (2) meet specific distributed database, data access, and data movement needs of national and international climate projects; (3) provide a universal and secure web-based data access portal for broad multi-model data collections; and (4) provide a wide-range of Grid-enabled climate data analysis tools and diagnostic methods to international climate centers and U.S. government agencies. Building on the successes of the previous Earth System Grid (ESG) project, which has enabled thousands of researchers to access tens of terabytes of data from a small number of ESG sites, ESG-CET is working to integrate a far larger number of distributed data providers, high-bandwidth wide-area networks, and remote computers in a highly collaborative problem-solving environment.

Optimization of micro-grid system using MOPSO  

Science Journals Connector (OSTI)

Abstract Access to a reliable source of electricity is a basic need for any community as it can improve the living standards characterized via the improvement of healthcare, education, and the local economy at large. There are two key factors to consider when assessing the appropriateness of a micro-grid system, the cost-effectiveness of the system and the quality of service. The tradeoff between cost and reliability of the system is a major compromise in designing hybrid systems. In this way, optimization of a Hybrid Micro-Grid System (HMGS) is investigated. A hybrid wind/PV system with battery storage and diesel generator is used for this purpose. The power management algorithm is applied to the load, and the Multi-Objective Particle Swarm Optimization (MOPSO) method is used to find the best configuration of the system and for sizing the components. A set of recent hourly wind speed data from three meteorological stations in Iran, namely: Nahavand, Rafsanjan, and Khash, are selected and tested for the optimization of HMGS. Despite design complexity of the aforementioned systems, the results show that the MOPSO optimization model produces appropriate sizing of the components for each location. It is also suggested that the use of HMGS can be considered as a good alternative to promote electrification projects and enhance energy access within remote Iranian areas or other developing countries enjoying the same or similar climatic conditions.

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

Science Journals Connector (OSTI)

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

Earth System Grid II, Turning Climate Datasets into Community Resources  

SciTech Connect (OSTI)

The Earth System Grid (ESG) II project, funded by the Department of Energys Scientific Discovery through Advanced Computing program, has transformed climate data into community resources. ESG II has accomplished this goal by creating a virtual collaborative environment that links climate centers and users around the world to models and data via a computing Grid, which is based on the Department of Energys supercomputing resources and the Internet. Our projects success stems from partnerships between climate researchers and computer scientists to advance basic and applied research in the terrestrial, atmospheric, and oceanic sciences. By interfacing with other climate science projects, we have learned that commonly used methods to manage and remotely distribute data among related groups lack infrastructure and under-utilize existing technologies. Knowledge and expertise gained from ESG II have helped the climate community plan strategies to manage a rapidly growing data environment more effectively. Moreover, approaches and technologies developed under the ESG project have impacted datasimulation integration in other disciplines, such as astrophysics, molecular biology and materials science.

Methods of integrating a high penetration photovoltaic power plant into a micro grid.  

SciTech Connect (OSTI)

The island of Lanai is currently one of the highest penetration PV micro grids in the world, with the 1.2 MWAC La Ola Solar Farm operating on a grid with a peak net load of 4.7 MW. This facility interconnects to one of Lanai's three 12.47 kV distribution circuits. An initial interconnection requirements study (IRS) determined that several control and performance features are necessary to ensure safe and reliable operation of the island grid. These include power curtailment, power factor control, over/under voltage and frequency ride through, and power ramp rate limiting. While deemed necessary for stable grid operation, many of these features contradict the current IEEE 1547 interconnection requirements governing distributed generators. These controls have been successfully implemented, tested, and operated since January 2009. Currently, the system is producing power in a curtailed mode according to the requirements of a power purchase agreement (PPA).

Economic analysis of standalone and grid connected hybrid energy systems  

Science Journals Connector (OSTI)

A pilot region was selected and cost analysis of using renewable energy sources with a hydrogen system for that regions energy demand is introduced, in a techno-economic perspective, in this paper. The renewable energy potential for the region was evaluated by implementing energy cost analysis. The study also evaluates the feasibility of utilizing solar and wind energy with hydrogen as a storage unit to meet the electricity requirements of the pilot region as a standalone system and in conjunction with the conventional grid based electricity. In order to simulate the operation of the system and to calculate the technical and economic parameters, micropower optimization program Homer (NREL, US) was used in this study. Homer requires some input values, such as technological options, cost of components, and resource compliance; and then the program ranges the feasible system configurations according to the net present cost (system cost) by using these inputs. The pilot region in this study, where the renewable based energy will be used, is determined to be Electrics & Electronics Faculty, Istanbul Technical University.

Effect of different grid shapes in wireless mesh network-genetic algorithm system  

Science Journals Connector (OSTI)

Grid computing have emerged as scientific and technical work, where geographically distributed computers, are used to create virtual supercomputers of vast amount of computing capacity able to solve complex problems in less time than before. Thus, within the last years we have witnessed how grid computing has helped to achieve breakthroughs in meteorology, physics and other computing-intensive fields. Wireless Mesh Networks (WMNs) are particularly suited for providing the communications required for a robust, self-healing grid architecture. The good performance and operability of WMNs depend on placement of mesh routers nodes in the geographical deployment area. In this paper, we consider the grid topology and evaluate the performance of WMN-GA system for node placement problem in WMNs. We consider different distributions of mesh clients and different grid shapes. The simulation results show the effect of grid shapes in the performance of WMN-GA. The system performs better for normal distribution.

Sustainable energy future via grid interactive operation of spv system at isolated remote island  

Science Journals Connector (OSTI)

This paper has analyzed the case of Moushuni Island at Sundarban of 24 Parganas South of West Bengal, India. The proposition is to find out the possibility of grid-connectivity of Isolated Remote Island which is under rural electrification scheme by hybrid renewable energies under Jawaharlal Nehru National Solar Mission of India. In these rural electrification program, grid extension can be the best option if the grid is reliable, the rural community rather big and in proximity to the grid. In many circumstances, a strong case for mini-grids based on hybrid systems can be made. Scattered communities and isolated houses are well served by solar and small hydro (where available) or small wind energy systems. By feeding renewable electricity to the utility grid through the grid-connected hybrid renewable energy system, during time of peak demand, sufficient electrical loads can be shed to prevent turning on a coal or natural gas-fired plant and therefore save CO2 emissions and potentially energy import costs, replacing fossil fuels. The Social, Economic, and Environmental Benefits can be achieved through this proposition. Also, the Grid Interactive Operation of SPV System at Moushuni Island is tested. Malda district of West Bengal, India is a vision towards smart-grid city towards sustainable future, where rural consumers can upgrade their quality of life through solar energy resource.

Design and Analysis of the Poloidal Field Grid Power Supply System for the HT-7 Tokamak  

Science Journals Connector (OSTI)

This paper reports a new project - the poloidal field (PF) grid power supply system to replace the ac flywheel generator power supply system on the basis of the present running parameters of the HT-7 poloidal field and the short-circuit capacity of our transformer substation. The designed parameters of the PF grid power supply system have been verified to meet the requirements of the heating field (HF) and the vertical field (VF). In the meantime, in order to reduce the disturbance to the local power grid, the device of reactive power and harmonic current compensation has been added. Experimental results have confirmed the feasibility of the PF grid power supply system. Compared with the ac flywheel generator, the PF grid power supply system has the advantages of lower noise, precise control, convenient maintenance, simple operation and cost savings.

Power management of hybrid micro-grid system by a generic centralized supervisory control scheme  

Science Journals Connector (OSTI)

Abstract This paper presents a generic centralized supervisory control scheme for the power management of multiple power converters based hybrid micro-grid system. The system consists of wind generators, photovoltaic system, multiple parallel connected power converters, utility grid, ac and dc loads. Power management of the micro-grid is performed under two cases: grid mode and local mode. Central supervisory unit (CSU) generates command signal to ensure the power management during the two modes. In local mode, the dc loads in the acdc hybrid system can be controlled. In the case of grid mode operation, power flow between the utility grid and micro-grid is controlled. A novel feature of this paper is the incorporation of the multiple power converters. The generated command signal from the CSU can also control the operation of the multiple power converters in both grid and local modes. An additional feature is the incorporation of sodium sulfur battery energy storage system (NAS BESS) which is used to smooth the output power fluctuation of the wind farm. The effectiveness of the control scheme is also verified using real time load pattern. The simulation is performed in PSCAD/EMTDC.

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.

The Global Grid  

Science Journals Connector (OSTI)

This paper puts forward the vision that a natural future stage of the electricity network could be a grid spanning the whole planet and connecting most of the large power plants in the world: this is the Global Grid. The main driving force behind the Global Grid will be the harvesting of remote renewable sources, and its key infrastructure element will be the high capacity long transmission lines. Wind farms and solar power plants will supply load centers with green power over long distances. This paper focuses on the introduction of the concept, showing that a globally interconnected network can be technologically feasible and economically competitive. We further highlight the multiple opportunities emerging from a global electricity network such as smoothing the renewable energy supply and electricity demand, reducing the need for bulk storage, and reducing the volatility of the energy prices. We also discuss possible investment mechanisms and operating schemes. Among others, we envision in such a system a global power market and the establishment of two new coordinating bodies, the Global Regulator and the Global System Operator.

A grid-enabled MPI : message passing in heterogeneous distributed computing systems.  

SciTech Connect (OSTI)

Application development for high-performance distributed computing systems, or computational grids as they are sometimes called, requires grid-enabled tools that hide mundate aspects of the heterogeneous grid environment without compromising performance. As part of an investigation of these issues, they have developed MPICH-G, a grid-enabled implementation of the Message Passing Interface (MPI) that allows a user to run MPI programs across multiple computers at different sites using the same commands that would be used on a parallel computer. This library extends the Argonne MPICH implementation of MPI to use services provided by the globus grid toolkit. In this paper, they describe the MPICH-G implementation and present preliminary performance results.

Wind energy and system security the grid connection moratorium in Ireland  

Science Journals Connector (OSTI)

This examines the interaction between technical challenges and policy choices that are made regarding wind power, and uses the grid connection moratorium in Ireland as a case study. While total installed wind capacity in Ireland is low compared with Germany, Spain and Denmark, wind power penetration is higher in the Irish system than in either the British, UCTE or NORDEL systems. In December 2003 the system operators expressed concerns about high wind power penetration, in particular the challenges of maintaining power system stability, security and reliability, resulting in a moratorium on new grid connection agreements. Significant progress has since been made in grid codes and dynamic models for wind turbines. In March 2006, there remain almost 3000 MW of proposed wind capacity awaiting a grid connection agreement. This paper investigates the technical issues underpinning this moratorium, monitors progress made since its introduction and suggests alternative technical solutions to the moratorium.

Chapter 5 - Existing Markets for Storage Systems inOff-Grid Applications  

Science Journals Connector (OSTI)

Abstract The market for remote power sources that are not connected to the utility grid, the so-called off-grid application, is rapidly growing. Given that the costs of renewable energy, such as photovoltaic panels, are falling, the proportion of the overall cost that arises from energy storage is increasing. Up to 80% of the costs of off-grid systems are now due to storage. Hence, to reduce the cost of off-grid applications, it is necessary to reduce the cost of storing energy. Different sources of renewable energy have different demands for storage. In addition to the type of energy source, the kind of user also has a strong influence on the features of the storage system.

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.

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

Science Journals Connector (OSTI)

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

Relay coordination and protection failure effects on reliability indices in an interconnected sub-transmission system  

Science Journals Connector (OSTI)

Protection system failure is the main cause of cascading outages. It has been shown that the hidden failures lead to cascading outages. However, the effects of the coordination method as well as the hidden failure of the protection systems have not been investigated yet. In this paper, an algorithm based on sequential Monte Carlo simulation is proposed to find the reliability indices for different overcurrent relay coordination methods. The proposed algorithm is applied to the results of different relay coordination methods of a real network. The indices SAIFI, CAIDI, CAIFI and ENS for the results of different relay coordination methods are obtained strictly based on the contribution of the protection failure issues. Then, a comparison is made between the results of the different relay coordination methods in order to show how the coordination methods affect the reliability indices.

Sohn, Cody Rose, Junqiao Han Dudley, Sasank Goli, Sila Kiliccote, Marissa Hummon, David Palchak, Paul Denholm, Jennie Jorgenson, and Ookie Ma Date Published 09/2013 Abstract Demand response (DR) has the potential to improve electric grid reliability and reduce system operation costs. However, including DR in grid modeling can be difficult due to its variable and non-traditional response characteristics, compared to traditional generation. Therefore, efforts to value the participation of DR in procurement of grid services have been limited. In this report, we present methods and tools for predicting demand response availability profiles, representing their capability to participate in capacity, energy, and ancillary services. With the addition of response characteristics mimicking those of generation, the resulting profiles will help in the valuation of the participation of demand response through production cost modeling, which informs infrastructure and investment planning.

Direct power control of grid connected PV systems with three level NPC inverter  

SciTech Connect (OSTI)

This paper presents the control of a three-level Neutral Point Clamped (NPC) voltage source inverter for grid connected photovoltaic (PV) systems. The control method used is the Extended Direct Power Control (EDPC), which is a generic approach for Direct Power Control (DPC) of multilevel inverters based on geometrical considerations. Maximum Power Point Tracking (MPPT) algorithms, that allow maximal power conversion into the grid, have been included. These methods are capable of extracting maximum power from each of the independent PV arrays connected to each DC link voltage level. The first one is a conventional MPPT which outputs DC link voltage references to EDPC. The second one is based on DPC concept. This new MPPT outputs power increment references to EDPC, thus avoiding the use of a DC link voltage regulator. The whole control system has been tested on a three-level NPC voltage source inverter connected to the grid and results confirm the validity of the method. (author)

Cyber security in the Smart Grid: Survey and challenges  

Science Journals Connector (OSTI)

The Smart Grid, generally referred to as the next-generation power system, is considered as a revolutionary and evolutionary regime of existing power grids. More importantly, with the integration of advanced computing and communication technologies, the Smart Grid is expected to greatly enhance efficiency and reliability of future power systems with renewable energy resources, as well as distributed intelligence and demand response. Along with the silent features of the Smart Grid, cyber security emerges to be a critical issue because millions of electronic devices are inter-connected via communication networks throughout critical power facilities, which has an immediate impact on reliability of such a widespread infrastructure. In this paper, we present a comprehensive survey of cyber security issues for the Smart Grid. Specifically, we focus on reviewing and discussing security requirements, network vulnerabilities, attack countermeasures, secure communication protocols and architectures in the Smart Grid. We aim to provide a deep understanding of security vulnerabilities and solutions in the Smart Grid and shed light on future research directions for Smart Grid security.

Grid-friendly wind power systems based on the synchronverter technology  

Science Journals Connector (OSTI)

Abstract Back-to-back PWM converters are becoming a realistic alternative to conventional converters in high-power wind power applications. In this paper, a control strategy based on the synchronverter technology is proposed for back-to-back PWM converters. Both converters are run as synchronverters, which are mathematically equivalent to the conventional synchronous generators. The rotor-side converter is responsible for maintaining the DC link voltage and the grid-side converter is responsible for the maximum power point tracking (MPPT). As the two converters are operated using the synchronverter technology, the formed wind power system becomes more friendly to the grid. Extensive real-time digital simulation results are presented to verify the effectiveness of the proposed method under normal operation and grid-fault scenarios.

Probability-Based Software for Grid Optimization: Improved Power System Operations Using Advanced Stochastic Optimization  

SciTech Connect (OSTI)

GENI Project: Sandia National Laboratories is working with several commercial and university partners to develop software for market management systems (MMSs) that enable greater use of renewable energy sources throughout the grid. MMSs are used to securely and optimally determine which energy resources should be used to service energy demand across the country. Contributions of electricity to the grid from renewable energy sources such as wind and solar are intermittent, introducing complications for MMSs, which have trouble accommodating the multiple sources of price and supply uncertainties associated with bringing these new types of energy into the grid. Sandias software will bring a new, probability-based formulation to account for these uncertainties. By factoring in various probability scenarios for electricity production from renewable energy sources in real time, Sandias formula can reduce the risk of inefficient electricity transmission, save ratepayers money, conserve power, and support the future use of renewable energy.

Wavelet technique based islanding detection and improved repetitive current control for reliable operation of grid-connected PV systems  

Science Journals Connector (OSTI)

Abstract Recent years have witnessed a thrust towards the use of solar energy as the major renewable energy source for distributed power generation. The proposed system requires reliable detection technique and suitable current control strategy for proper operation. This paper focuses on plug-in repetitive current (RC) control strategy for grid connected inverter system and wavelet technique for electrical grid status identification. The performance of proposed current control technique employed for grid connected inverter system under distorted and unbalanced grid voltage is compared with the existing conventional methods like PI and PR controller. This controller uses the feedback control system for attenuating periodic disturbances, improving high quality sinusoidal output current and high power factor. The proposed scheme employs fourth order infinite impulse response (IIR) filter for maintaining its resonance frequency, output frequency matching with grid fundamental frequency and reduction of harmonics. The DC-DC boost converter implements incremental conductance based (INC) maximum power point tracker (MPPT) algorithm. The effects of LCL filter for improving disturbance rejection capability and dynamic performance of the proposed system is also demonstrated. Grid connected PV inverter employs wavelet technique for an islanding detection functionality in order to determine the status of the electrical grid. In order to show the effectiveness of the proposed algorithm, modeling and simulation for grid connected PV system is performed using MATLAB/SIMULINK and its PowerSim toolbox.

4th Generation District Heating (4GDH): Integrating smart thermal grids into future sustainable energy systems  

Science Journals Connector (OSTI)

Abstract This paper defines the concept of 4th Generation District Heating (4GDH) including the relations to District Cooling and the concepts of smart energy and smart thermal grids. The motive is to identify the future challenges of reaching a future renewable non-fossil heat supply as part of the implementation of overall sustainable energy systems. The basic assumption is that district heating and cooling has an important role to play in future sustainable energy systems including 100 percent renewable energy systems but the present generation of district heating and cooling technologies will have to be developed further into a new generation in order to play such a role. Unlike the first three generations, the development of 4GDH involves meeting the challenge of more energy efficient buildings as well as being an integrated part of the operation of smart energy systems, i.e. integrated smart electricity, gas and thermal grids.

This report provides a baseline description of the transmission issues affecting geothermal technologies. The report begins with a comprehensive overview of the grid, how it is planned, how it is used, and how it is paid for. The report then overlays onto this 'big picture' three types of geothermal technologies: conventional hydrothermal systems; emerging technologies such as enhanced engineered geothermal systems (EGS) and geopressured geothermal; and geothermal co-production with existing oil and gas wells. Each category of geothermal technology has its own set of interconnection issues, and these are examined separately for each. The report draws conclusions about each technology's market affinities as defined by factors related to transmission and distribution infrastructure. It finishes with an assessment of selected markets with known geothermal potential, identifying those that offer the best prospects for near-term commercial development and for demonstration projects.

An improved framework for power grid vulnerability analysis considering critical system features  

Science Journals Connector (OSTI)

Abstract In recent years the rapid development of complex network theory has provided a new angle on the vulnerability analysis of a power grid. However, current analysis models are usually general ones that may ignore some specific features of power systems. In order to address the issue, this paper proposes an improved framework for the vulnerability analysis of power grids. Firstly, the traditional topology based graph model is improved by depicting a power grid as a weighted graph based on the reactance matrix. Secondly, the concept of load is redefined by using power angle information. Thirdly, the power flow constraints are adopted instead of the shortest path based flow scheme. Based on the proposed framework, an improved dynamic analysis model is developed. In addition, numerical simulations for both a general traditional model and the proposed model are investigated based on the IEEE 118-bus system respectively. The comparison demonstrates that the improved model is more effective and efficient for the vulnerability analysis of a power grid.

A novel air-conditioning system for proactive power demand response to smart grid  

Science Journals Connector (OSTI)

Abstract Power demand response is considered as one of the most promising solutions in relieving the power imbalance of an electrical grid that results a series of critical problems to the gird and end-users. In order to effectively make use of the demand response potentials of buildings, this paper presents a novel air-conditioning system with proactive demand control for daily load shifting and real time power balance in the developing smart grid. This system consists of a chilled water storage system (CWS) and a temperature and humidity independent control (THIC) air-conditioning system, which can significantly reduce the storage volume of the chilled water tank and effectively enable a building with more flexibility in changing its electricity usage patterns. The power demand of the proposed air-conditioning system can be flexibly controlled as desired by implementing two types of demand response strategies: demand side bidding (DSB) strategy and demand as frequency controlled reserve (DFR) strategy, in respond to the day-ahead and hour-ahead power change requirements of the grid, respectively. Considerable benefits (e.g., energy and cost savings) can be achieved for both the electricity utilities and building owners under incentive pricing or tariffs. A case study is conducted in a simulation platform to demonstrate the application of the proposed system in an office building.

A sociotechnical systems model for smart-grid adoption in mid-sized urban environments  

Science Journals Connector (OSTI)

In this paper, we present a quantified system dynamics model simulating the adoption of smart grid technologies such as electric vehicles, PV systems and smart meters in a mid-sized urban system and the resulting impact on the CO2 emissions. We also analyse the impact of different subsidies on the adoption and calculate the effectiveness regarding public and private spending on these technologies in order to derive a strategy for policy making. The results show that even in an ideal scenario the emissions cannot be reduced enough to outweigh additional emissions caused by the population growth. Hence smart grid technologies can only be one part of a greater strategy in order to make cities more sustainable.

Modelling elements of Smart Grids Enhancing the \\{OSeMOSYS\\} (Open Source Energy Modelling System) code  

Science Journals Connector (OSTI)

Smart Grids are expected to help facilitate a better integration of distributed storage and demand response options into power systems and markets. Quantifying the associated system benefits may provide valuable design and policy insights. Yet many existing energy system models are not able to depict various critical features associated with Smart Grids in a single comprehensive framework. These features may for example include grid stability issues in a system with several flexible demand types and storage options to help balance a high penetration of renewable energy. Flexible and accessible tools have the potential to fill this niche. This paper expands on the Open Source Energy Modelling System (OSeMOSYS). It describes how blocks of functionality may be added to represent variability in electricity generation, a prioritisation of demand types, shifting demand, and storage options. The paper demonstrates the flexibility and ease-of-use of \\{OSeMOSYS\\} with regard to modifications of its code. It may therefore serve as a useful test-bed for new functionality in tools with wide-spread use and larger applications, such as MESSAGE, TIMES, MARKAL, or LEAP. As with the core code of OSeMOSYS, the functional blocks described in this paper are available in the public domain.

Constructing the ASCI computational grid  

SciTech Connect (OSTI)

The Accelerated Strategic Computing Initiative (ASCI) computational grid is being constructed to interconnect the high performance computing resources of the nuclear weapons complex. The grid will simplify access to the diverse computing, storage, network, and visualization resources, and will enable the coordinated use of shared resources regardless of location. To match existing hardware platforms, required security services, and current simulation practices, the Globus MetaComputing Toolkit was selected to provide core grid services. The ASCI grid extends Globus functionality by operating as an independent grid, incorporating Kerberos-based security, interfacing to Sandia's Cplant{trademark},and extending job monitoring services. To fully meet ASCI's needs, the architecture layers distributed work management and criteria-driven resource selection services on top of Globus. These services simplify the grid interface by allowing users to simply request ''run code X anywhere''. This paper describes the initial design and prototype of the ASCI grid.

Grid Simulation Grid Simulation NREL's controllable grid interface test system can reduce certification testing time and costs while providing system engineers with a better understanding of how wind turbines react to disturbances on the electric power system. To understand the behavior of wind turbines during grid disturbances, manufacturers and utility grid operators perform a series of tests and transient simulation studies. Utility operators need to estimate how much power wind turbines can provide to help regulate grid frequency. And after design modifications are made to control software, manufacturers may need to retest their turbines. But testing wind turbines in the field can be a lengthy and expensive process.

Visual Analytics for Power Grid Contingency Analysis  

SciTech Connect (OSTI)

Contingency analysis is the process of employing different measures to model scenarios, analyze them, and then derive the best response to remove the threats. This application paper focuses on a class of contingency analysis problems found in the power grid management system. A power grid is a geographically distributed interconnected transmission network that transmits and delivers electricity from generators to end users. The power grid contingency analysis problem is increasingly important because of both the growing size of the underlying raw data that need to be analyzed and the urgency to deliver working solutions in an aggressive timeframe. Failure to do so may bring significant financial, economic, and security impacts to all parties involved and the society at large. The paper presents a scalable visual analytics pipeline that transforms about 100 million contingency scenarios to a manageable size and form for grid operators to examine different scenarios and come up with preventive or mitigation strategies to address the problems in a predictive and timely manner. Great attention is given to the computational scalability, information scalability, visual scalability, and display scalability issues surrounding the data analytics pipeline. Most of the large-scale computation requirements of our work are conducted on a Cray XMT multi-threaded parallel computer. The paper demonstrates a number of examples using western North American power grid models and data.

Optimal Power System and Grid Interface Design Considerations for the CLICs Klystron Modulators  

E-Print Network [OSTI]

The Compact Linear Collider (CLIC) is an electron-positron collider under study at CERN with the aim to explore the next generation of high precision/high energy particles physics. The CLICs drive beams will be accelerated by approximately 1300 klystrons, requiring highly efficient and controllable solid state capacitor discharge modulators. Capacitor charger specifications include the requirement to mask the pulsed effect of the load from the utility grid, ensure maximum power quality, control the derived DC voltage precisely (to maximize accuracy for the modulators being implemented), and achieve high efficiency and operability of the overall power system. This paper presents the work carried out on the power system interface for the CLIC facility. In particular it discusses the challenges on the utility interface and analysis of the grid interface converters with regards to required functionality, efficiency, and control methodologies.

The Development of Interconnection Standards in Six States In 2007-2008  

SciTech Connect (OSTI)

This paper discusses the process of developing standards for the interconnection of photovoltaic systems and other generators under ten megawatts to the electric grid. State utility commission rulemakings in 2007-2008 in Florida, New Mexico, North Carolina, Maryland, Illinois and Utah provide the basis for analysis of what is and should be considered in the development of standards, and how the process can be improved. State interconnection standards vary substantially, and many utilities have discretion to establish additional or different requirements, creating literally hundreds of sets of rules. This lack of uniformity imposes a significant cost on project developers and installers to track and comply with applicable rules. As well, burdensome provisions and uncertain costs and timelines present formidable barriers to entry, which advocates have limited resources to challenge. For a better process, the author proposes: establishing federal standards as a baseline, involving solar advocates, and developing a utility cost-recovery mechanism.

Measurement system design and implementation for grid-connected marine substation  

Science Journals Connector (OSTI)

A marine substation for a grid-connected wave power plant has been designed and constructed at Uppsala University. The measurement system for the substation has been developed from basics, and the procedure is described in this article. Subsea electrical installations set high constraints on the control and data acquisition systems used, and traditional GSM networks and GPS time synchronization aredifficult and inefficient. These circumstances exclude many well-proven methods to be utilized. AcompactRIO-based system, with integrated real-time controller and Field-Programmable Gate Array chip, is chosen as most suitable for this task. The system is designed to meet the special requirements encountered in this unusual application, including large data sampling, grid connection control and protection systems. The system is communicating to shore via a subsea copper cable and single-pair high-speed digital subscriber line modems. The design was successful and full-fills all the system requirements. The aim of the article is to provide future researchers with a good design and implementation procedure for setting up large measurement systems.

Using annual numbers provides a reasonable estimation of emissions, but it provides no indication of the temporal nature of the emissions. Therefore, there is no way of understanding the impact on emissions from load shifting and peak shaving technologies such as thermal energy storage, on-site renewable energy, and demand control.

Modeling Framework and Validation of a Smart Grid and Demand Response System for Wind Power Integration  

SciTech Connect (OSTI)

Electricity generation from wind power and other renewable energy sources is increasing, and their variability introduces new challenges to the power system. The emergence of smart grid technologies in recent years has seen a paradigm shift in redefining the electrical system of the future, in which controlled response of the demand side is used to balance fluctuations and intermittencies from the generation side. This paper presents a modeling framework for an integrated electricity system where loads become an additional resource. The agent-based model represents a smart grid power system integrating generators, transmission, distribution, loads and market. The model incorporates generator and load controllers, allowing suppliers and demanders to bid into a Real-Time Pricing (RTP) electricity market. The modeling framework is applied to represent a physical demonstration project conducted on the Olympic Peninsula, Washington, USA, and validation simulations are performed using actual dynamic data. Wind power is then introduced into the power generation mix illustrating the potential of demand response to mitigate the impact of wind power variability, primarily through thermostatically controlled loads. The results also indicate that effective implementation of Demand Response (DR) to assist integration of variable renewable energy resources requires a diversity of loads to ensure functionality of the overall system.

Decompression cooling system operation for HTS power cable in the KEPCO power grid  

Science Journals Connector (OSTI)

A 3-phase 22.9 kV/50 MVA 410 m HTS power cable system was installed at power grid of KEPCO and had been operated for 20 months. In the HTS cable system an open type cooling system was constructed for cooling LN2 using as coolant for superconducting cable. The cooling capacity of the cooling system was 6 kW at 69 K. Subcooled LN2 flew thorough 410 m HTS cable maintaining 69 K of operating temperature for HTS cable. The electric load had fluctuated continuously with the load status so that the cooling state was also controlled to keep stable operating condition. The consumed LN2 used for making subcooled state was refilled periodically and the amount was 3 tons in average. During all the operating period the HTS cable system supplied electric power stably without any problem.

Exploration of the integration of renewable resources into California's electric system using the Holistic Grid Resource Integration and Deployment (HiGRID) tool  

Science Journals Connector (OSTI)

Renewable resources represent an opportunity for environmentally preferred generation of electricity that supports energy security and independence; however integrating renewable technologies is not without challenges. Renewable resources have limitations that can include location, capacity, cost and availability. California is proactive in the implementation of renewable energy through legislation and execution of a Renewable Portfolio Standard. This work explores key challenges to achieving high penetrations of renewables onto California's grid. The Holistic Grid Resource Integration and Deployment (HiGRID) tool has been developed for this analysis and is verified herein. This tool resolves the hourly operation, performance and cost of renewable and non-renewable generation resources. Three renewable deployment strategies are explored including all wind, all solar photovoltaic, and 50/50 mixture. Initially, wind is the preferred candidate from a cost and required installed capacity perspective; however, as the penetration increases excess wind generation encourages installation of solar. The 50/50 case becomes more cost competitive at high renewable penetrations (greater than 32.4%) and provides the highest system-wide capacity factor and CO2 reduction potential. Results highlight the value of optimizing the renewable deployment strategy to minimize costs and emphasize the importance of considering capacity factor and curtailment when representing the true cost of installing renewables.

Reaching Grid Parity Using BP Solar Crystalline Silicon Technology: A Systems Class Application  

SciTech Connect (OSTI)

The primary target market for this program was the residential and commercial PV markets, drawing on BP Solar's premium product and service offerings, brand and marketing strength, and unique routes to market. These two markets were chosen because: (1) in 2005 they represented more than 50% of the overall US PV market; (2) they are the two markets that will likely meet grid parity first; and (3) they are the two market segments in which product development can lead to the added value necessary to generate market growth before reaching grid parity. Federal investment in this program resulted in substantial progress toward the DOE TPP target, providing significant advancements in the following areas: (1) Lower component costs particularly the modules and inverters. (2) Increased availability and lower cost of silicon feedstock. (3) Product specifically developed for residential and commercial applications. (4) Reducing the cost of installation through optimization of the products. (5) Increased value of electricity in mid-term to drive volume increases, via the green grid technology. (6) Large scale manufacture of PV products in the US, generating increased US employment in manufacturing and installation. To achieve these goals BP Solar assembled a team that included suppliers of critical materials, automated equipment developers/manufacturers, inverter and other BOS manufacturers, a utility company, and University research groups. The program addressed all aspects of the crystalline silicon PV business from raw materials (particularly silicon feedstock) through installation of the system on the customers site. By involving the material and equipment vendors, we ensured that supplies of silicon feedstock and other PV specific materials like encapsulation materials (EVA and cover glass) will be available in the quantities required to meet the DOE goals of 5 to 10 GW of installed US PV by 2015 and at the prices necessary for PV systems to reach grid parity in 2015. This final technical report highlights the accomplishments of the BP Solar technical team from 2006 to the end of the project in February 2010. All the main contributors and team members are recognized for this accomplishment and their endeavors are recorded in the twelve main tasks described here.

Public Response to Residential Grid-Tied PV Systems in Colorado: A Qualitative Market Assessment  

SciTech Connect (OSTI)

The early adopters of residential grid-tied photovoltaics (PV) have complex motivations to pay today's costs, including altruistic, environmental, and financial reasons. Focused interviews were conducted with a self-selected purposive sample interested in purchasing 2-kW or 3-kW PV systems with an installed cost of $8,000 to $12,000. The sample tended to be men or married couples ranging in age from their early thirties to their mid-eighties; professionals, managers, or small business owners; relatively financially secure, with experience with energy efficiency and renewable energy. Product attributes they preferred were net metering, warranties, guarantees, utility financing, maintenance, an option to own or lease, a battery option, and an aesthetically pleasing system. Potential PV customers needed more information before making a purchase decision.

A composite grid solver for conjugate heat transfer in fluid-structure systems  

SciTech Connect (OSTI)

We describe a numerical method for modeling temperature-dependent fluid flow coupled to heat transfer in solids. This approach to conjugate heat transfer can be used to compute transient and steady state solutions to a wide range of fluid-solid systems in complex two- and three-dimensional geometry. Fluids are modeled with the temperature-dependent incompressible Navier-Stokes equations using the Boussinesq approximation. Solids with heat transfer are modeled with the heat equation. Appropriate interface equations are applied to couple the solutions across different domains. The computational region is divided into a number of sub-domains corresponding to fluid domains and solid domains. There may be multiple fluid domains and multiple solid domains. Each fluid or solid sub-domain is discretized with an overlapping grid. The entire region is associated with a composite grid which is the union of the overlapping grids for the sub-domains. A different physics solver (fluid solver or solid solver) is associated with each sub-domain. A higher-level multi-domain solver manages the entire solution process. We propose and analyze some centered discrete approximations to the interface equations that have some desirable stability properties. The coupled interface equations may be solved directly when using explicit time-stepping methods in the sub-domains, resulting in a strongly coupled approach. The stability of the interface treatment in this case is independent of the relative sizes of the material properties in the two domains with the time-step only depending on the usual von Neumann conditions for each sub-domain. For implicit time-stepping methods we solve the interface equations in a weakly coupled fashion to avoid forming a coupled implicit system across all sub-domains. The convergence of this approach does depend on the relative sizes of the thermal conductivities and diffusivities. We analyze different iteration strategies for solving these implicit equations including the use of mixed (Robin) approximations at the interface. Numerical results are presented to illustrate the method. The accuracy of the technique is verified using the method of analytic solutions and by computing the solution to some heat exchanger problems where the exact solution is known. The technique is also applied to the modeling of an inertial-confinement-fusion hohlraum target and the flow of coolant past an hexagonal array of heated fuel rods. The multi-domain solver runs in parallel on distributed memory computers and some parallel results are provided.

Science Journals Connector (OSTI)

Abstract Several factors must be considered before adopting a full-phase power generation system based on renewable energy sources. Long-term necessary data (for one year if possible) should be collected before making any decisions concerning implementation of such a systems. To accurately assess the potential of available resources, we measured solar irradiation, wind speed, and ambient temperature at two high-altitude locations in Nepal: the Lama Hotel in Rasuwa District and Thingan in Makawanpur District. Here, we propose two practical, economical hybridization methods for small off-grid systems consisting entirely of renewable energy sourcesspecifically solar photovoltaic (PV), wind, and micro-hydro sources. One of the methods was tested experimentally, and the results can be applied to help achieve Millennium Development Goal 7: Ensuring environmental sustainability. Hydro, wind, and solar photovoltaic energy are the top renewable energy sources in terms of globally installed capacity. However, no reports have been published about off-grid hybrid systems comprised of all three sources, making this implementation the first of its kind anywhere. This research may be applied as a practical guide for implementing similar systems in various locations. Of the four off-grid PV systems installed by the authors for village electrification in Nepal, one was further hybridized with wind and hydro power sources. This paper presents a novel approach for connecting renewable energy sources to a utility mini-grid.

Optimum penetration of utility-scale grid-connected solar photovoltaic systems in Illinois  

Science Journals Connector (OSTI)

Abstract Although solar photovoltaics (PV) are recognized as a promising source of clean energy production, researchers and policy makers need to know the optimum level of solar PV capacity penetration into the existing generation structure under the current fuel mix for the region. As the level of installed PV capacity increases, it is possible that the aggregated generation mix could produce electrical power exceeding electrical demand, thus requiring generator curtailment. Therefore, determining the optimum penetration of large-scale PV and aggregated technical and economic benefits is becoming an issue for both power utilities and policy makers. We report the development and validation of a new methodology for assessing the optimum capacity and benefits of state-wide grid-connected large scale solar PV systems in Illinois. The solar carve-out portion of the current renewable portfolio standard is also evaluated within the context of the state's sustainable energy plan for the near term future.

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.

A new hybrid pneumatic combustion engine to improve fuel consumption of windDiesel power system for non-interconnected areas  

Science Journals Connector (OSTI)

This paper presents an evaluation of an optimized Hybrid Pneumatic-Combustion Engine (HPCE) concept that permits reducing fuel consumption for electricity production in non-interconnected remote areas, originally equipped with hybrid WindDiesel System (WDS). Up to now, most of the studies on the pneumatic hybridization of Internal Combustion Engines (ICE) have dealt with two-stroke pure pneumatic mode. The few studies that have dealt with hybrid pneumatic-combustion four-stroke mode require adding a supplementary valve to charge compressed air in the combustion chamber. This modification means that a new cylinder head should be fabricated. Moreover, those studies focus on spark ignition engines and are not yet validated for Diesel engines. Present HPCE is capable of making a Diesel engine operate under two-stroke pneumatic motor mode, two-stroke pneumatic pump mode and four-stroke hybrid mode, without needing an additional valve in the combustion chamber. This fact constitutes this studys strength and innovation. The evaluation of the concept is based on ideal thermodynamic cycle modeling. The optimized valve actuation timings for all modes lead to generic maps that are independent of the engine size. The fuel economy is calculated for a known site during a whole year, function of the air storage volume and the wind power penetration rate.

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%.

Real-space grids and the Octopus code as tools for the development of new simulation approaches for electronic systems  

E-Print Network [OSTI]

Real-space grids are a powerful alternative for the simulation of electronic systems. One of the main advantages of the approach is the flexibility and simplicity of working directly in real space where the different fields are discretized on a grid, combined with competitive numerical performance and great potential for parallelization. These properties constitute a great advantage at the time of implementing and testing new physical models. Based on our experience with the Octopus code, in this article we discuss how the real-space approach has allowed for the recent development of new ideas for the simulation of electronic systems. Among these applications are approaches to calculate response properties, modeling of photoemission, optimal control of quantum systems, simulation of plasmonic systems, and the exact solution of the Schr\\"odinger equation for low-dimensionality systems.

Analysis of off-grid hybrid wind turbine/solar PV water pumping systems  

Science Journals Connector (OSTI)

While many remote water pumping systems exist (e.g. mechanical windmills, solar photovoltaic, wind-electric, diesel powered), few combine both the wind and solar energy resources to possibly improve the reliability and the performance of the system. In this paper, off-grid wind turbine (WT) and solar photovoltaic (PV) array water pumping systems were analyzed individually and combined as a hybrid system. The objectives were to determine: (1) advantages or disadvantages of using a hybrid system over using a WT or a solar PV array alone; (2) if the WT or solar PV array interfered with the output of the other; and (3) which hybrid system was the most efficient for the location. The WT used in the analysis was rated at 900W alternating current (AC). There were three different solar PV arrays analyzed, and they were rated at 320, 480, and 640W direct current (DC). A rectifier converted the 3-phase variable voltage AC output from the WT to DC before combining it with the solar PV array DC output. The combined renewable energies powered a single helical pump. The independent variable used in the hybrid WT/PV array analysis was in units of W/m2. The peak pump efficiency of the hybrid systems at Bushland, TX occurred for the 900W WT combined with the 640W PV array. The peak pump efficiencies at a 75m pumping depth of the hybrid systems were: 47% (WT/320W PV array), 51% (WT/480W PV array), and 55% (WT/640W PV array). Interference occurred between the WT and the different PV arrays (likely due to voltage mismatch between WT and PV array), but the least interference occurred for the WT/320W PV array. This hybrid system pumped 28% more water during the greatest water demand month than the WT and PV systems would have pumped individually. An additional controller with a buck/boost converter is discussed at end of paper for improvement of the hybrid WT/PV array water pumping system.

The Earth System Grid Federation: An Open Infrastructure for Access to Distributed Geospatial Data  

SciTech Connect (OSTI)

The Earth System Grid Federation (ESGF) is a multi-agency, international collaboration that aims at developing the software infrastructure needed to facilitate and empower the study of climate change on a global scale. The ESGF s architecture employs a system of geographically distributed peer nodes, which are independently administered yet united by the adoption of common federation protocols and application programming interfaces (APIs). The cornerstones of its interoperability are the peer-to-peer messaging that is continuously exchanged among all nodes in the federation; a shared architecture and API for search and discovery; and a security infrastructure based on industry standards (OpenID, SSL, GSI and SAML). The ESGF software is developed collaboratively across institutional boundaries and made available to the community as open source. It has now been adopted by multiple Earth science projects and allows access to petabytes of geophysical data, including the entire model output used for the next international assessment report on climate change (IPCC-AR5) and a suite of satellite observations (obs4MIPs) and reanalysis data sets (ANA4MIPs).

Operation strategy for a lab-scale grid-connected photovoltaic generation system integrated with battery energy storage  

Science Journals Connector (OSTI)

Abstract The operation strategy for a lab-scale grid-connected photovoltaic generation system integrated with battery energy storage is proposed in this paper. The photovoltaic generation system is composed of a full-bridge inverter, a DCDC boost converter, an isolated bidirectional DCDC converter, a solar cell array and a battery set. Since the battery set acts as an energy buffer to adjust the power generation of the solar cell array, the negative impact on power quality caused by the intermittent and unstable output power from a solar cell array is alleviated, so the penetration rate of the grid-connected photovoltaic generation system is increased. A lab-scale prototype is developed to verify the performance of the system. The experimental results show that it achieves the expected performance.

Participation of wind power plants in system frequency control: Review of grid code requirements and control methods  

Science Journals Connector (OSTI)

Abstract Active power reserves are needed for the proper operation of an electrical system. These reserves are continuously regulated in order to match the generation and consumption in the system and thus, to maintain a constant electrical frequency. They are usually provided by synchronized conventional generating units such as hydraulic or thermal power plants. With the progressive displacement of these generating plants by non-synchronized renewable-based power plants (e.g. wind and solar) the net level of synchronous power reserves in the system becomes reduced. Therefore, wind power plants are required, according to some European Grid Codes, to also provide power reserves like conventional generating units do. This paper focuses not only on the review of the requirements set by Grid Codes, but also on control methods of wind turbines for their participation in primary frequency control and synthetic inertia.

Development of Resource Sharing System Components for AliEn Grid Infrastructure  

E-Print Network [OSTI]

The problem of the resource provision, sharing, accounting and use represents a principal issue in the contemporary scientific cyberinfrastructures. For example, collaborations in physics, astrophysics, Earth science, biology and medicine need to store huge amounts of data (of the order of several petabytes) as well as to conduct highly intensive computations. The appropriate computing and storage capacities cannot be ensured by one (even very large) research center. The modern approach to the solution of this problem suggests exploitation of computational and data storage facilities of the centers participating in collaborations. The most advanced implementation of this approach is based on Grid technologies, which enable effective work of the members of collaborations regardless of their geographical location. Currently there are several tens of Grid infrastructures deployed all over the world. The Grid infrastructures of CERN Large Hadron Collider experiments - ALICE, ATLAS, CMS, and LHCb which are exploi...

Towards understanding the benefits and challenges of Smart/Micro-Grid for electricity supply system in Nigeria  

Science Journals Connector (OSTI)

Abstract The poor state of electricity supply system in Nigeria is threatening the welfare and security of life and properties of millions of individuals with adverse economic consequences for the country. The inadequacy of the national grid, especially the inability of the electricity generation capacity to match increasing demand in the country has led to increasing agitation for increased penetration of renewable energy sources (RESs) into the electricity supply mix. While great attention has been focused on the potential of \\{RESs\\} for electricity generation in the country, little or no attention has been given to the application of Smart/Micro-Grid (SM-G) technologies to the ageing Nigeria grid infrastructures and electrification of the rural areas. The aim of this paper is to bring into focus the benefits and challenges of enabling SM-G in the electricity supply system in Nigeria. SM-G will bring benefits to the electricity stakeholders in form of improvements in reliability, efficiency, economics, environment, security and safety. The paper gives an overview and reviews the current state of the electricity supply system in the country. It discusses the SM-G concepts and associated technologies, and highlights how they can help address the electricity problems in the country. The challenges of applying these concepts in Nigeria context are also discussed. Enabling SM-G in the country will not only lead to improvement in the quality, efficiency and reliability of the electricity grid, but also promote the provision of electricity supply to the remote rural areas using RESs.

Operational Strategies for Battery Storage Systems in Low-voltage Distribution Grids to Limit the Feed-in Power of Roof-mounted Solar Power Systems  

Science Journals Connector (OSTI)

Abstract Due to the high amount of installed solar power systems in Germany, the low-voltage distribution grids reach their maximum capacities in periods of high insolation. In order to ensure a proper integration of today's and especially the prospective solar energy, grid reinforcement is a common method to increase the transmission capacity. As an alternative to this costly and intricate approach, local battery storage systems can be used to store the surplus generation and limit the feed-in power of the solar power systems. In this paper, two different operational strategies for battery storage systems together with solar power systems for self-consumption are presented and evaluated. Results show that the feed-in power can be distinctly reduced without generating significant losses for the system-owner.

Demonstration of a Novel Synchrophasor-based Situational Awareness System: Wide Area Power System Visualization, On-line Event Replay and Early Warning of Grid Problems  

SciTech Connect (OSTI)

Since the large North Eastern power system blackout on August 14, 2003, U.S. electric utilities have spent lot of effort on preventing power system cascading outages. Two of the main causes of the August 14, 2003 blackout were inadequate situational awareness and inadequate operator training In addition to the enhancements of the infrastructure of the interconnected power systems, more research and development of advanced power system applications are required for improving the wide-area security monitoring, operation and planning in order to prevent large- scale cascading outages of interconnected power systems. It is critically important for improving the wide-area situation awareness of the operators or operational engineers and regional reliability coordinators of large interconnected systems. With the installation of large number of phasor measurement units (PMU) and the related communication infrastructure, it will be possible to improve the operators situation awareness and to quickly identify the sequence of events during a large system disturbance for the post-event analysis using the real-time or historical synchrophasor data. The purpose of this project was to develop and demonstrate a novel synchrophasor-based comprehensive situational awareness system for control centers of power transmission systems. The developed system named WASA (Wide Area Situation Awareness) is intended to improve situational awareness at control centers of the power system operators and regional reliability coordinators. It consists of following main software modules: Wide-area visualizations of real-time frequency, voltage, and phase angle measurements and their contour displays for security monitoring. Online detection and location of a major event (location, time, size, and type, such as generator or line outage). Near-real-time event replay (in seconds) after a major event occurs. Early warning of potential wide-area stability problems. The system has been deployed and demonstrated at the Tennessee Valley Authority (TVA) and ISO New England system using real-time synchrophasor data from openPDC. Apart from the software product, the outcome of this project consists of a set of technical reports and papers describing the mathematical foundations and computational approaches of different tools and modules, implementation issues and considerations, lessons learned, and the results of lidation processes.

Economic evaluation of small-scale photovoltaic hybrid systems for mini-grid applications in far north Cameroon  

Science Journals Connector (OSTI)

A comparison between photovoltaic hybrid systems (PVHS), standalone photovoltaic (PV) and standalone diesel generator options is performed using the net present value (NPV) technique. A typical village mini-grid energy demand of 7.08kWh/day is considered in the computation of energy costs and breakeven grid distances. A first sensitivity analysis is conducted using remote diesel prices of 0.8/l, 0.98/l, 1.12/l, 1.28/l with a PV module cost of 7.5/Wp. A second sensitivity analysis is also done using PV module costs of 5.25/Wp, 6/Wp, 6.75/Wp, 7.5/Wp with a diesel price of 1.12/l. The energy cost for the diesel option was found to be 0.812/kWh at a diesel fuel price of 1.12/l. The sensitivity analyses showed that minimum energy costs were attained in PVHS at renewable energy fractions in the range 82.695.3%. In the second sensitivity analysis the energy costs and breakeven grid distances were found to be in the ranges 0.6920.785/kWh and 5.15.9km respectively. For a PV module cost of 5.25/Wp, the lowest energy cost for the PVHS option was 0.692/kWh at a final renewable energy fraction of 95.3% with the diesel generator hours being 37h compared to 2075h in the standalone diesel generator option. Consequently, a 30% reduction in custom duties and taxes on imported PV modules and sub-systems would increase the use of small-scale and climate friendly PV mini-grids in remote areas of far north Cameroon that have an annual insolation of at least 5.55kWh/m2/day.

Accelerating development of advanced inverters : evaluation of anti-islanding schemes with grid support functions and preliminary laboratory demonstration.  

SciTech Connect (OSTI)

The high penetration of utility interconnected photovoltaic (PV) systems is causing heightened concern over the effect that variable renewable generation will have on the electrical power system (EPS). These concerns have initiated the need to amend the utility interconnection standard to allow advanced inverter control functionalities that provide: (1) reactive power control for voltage support, (2) real power control for frequency support and (3) better tolerance of grid disturbances. These capabilities are aimed at minimizing the negative impact distributed PV systems may have on EPS voltage and frequency. Unfortunately, these advanced control functions may interfere with island detection schemes, and further development of advanced inverter functions requires a study of the effect of advanced functions on the efficacy of antiislanding schemes employed in industry. This report summarizes the analytical, simulation and experimental work to study interactions between advanced inverter functions and anti-islanding schemes being employed in distributed PV systems.

Techno-economic analysis of hybrid photovoltaic/diesel/battery off-grid system in northern Nigeria  

Science Journals Connector (OSTI)

The rate of dependence on stand-alone diesel generator for individual electricity generation among households in Nigeria is geometrically increasing and has thus led to significant increase of the environment pollution. This is due to the inability of the utility company to meet the energy demand of its yearning consumers due to ageing and limitations in power infrastructures. This has led to about 40% of the country's population been cut off from the national grid. In view of these hazardous effects posed from the usage of these individual diesel-powered generations this paper reports on the assessment of techno-economic viability of a hybrid photovoltaic diesel/battery off-grid system as an alternative solution to these threats. For that purpose a remote area located far in the northern part of Nigeria was taken as the case study in which an international institution with peak demand of 90?kW was considered. The HOMER optimization software is used to evaluate both the technical and economic viability of the proposed energy system by taking into account the variations of both the solar radiation and diesel prices as experienced in most part of Nigeria. The study reveals the potential capability of the hybrid photovoltaic/diesel energy system with battery backup as a good alternative energy source for individual household replacement for diesel-powered generator. In addition the proposed system is of high energy potential as well as low carbon emission at affordable cost of electricity.

A Novel Visualization Technique for Electric Power Grid Analytics  

SciTech Connect (OSTI)

The application of information visualization holds tremendous promise for the electric power industry, and yet its potential has not been sufficiently exploited by the visualization community. Prior work on visualizing electric power systems has been limited to depicting raw or processed information on top of a geographic layout. Little effort has been devoted to maximize the analytical strengths naturally gained by the visualization itself. This paper introduces a visualization system prototype, known as GreenGrid, that explores the planning and monitoring of the North American Electricity Infrastructure. For the purposes of visualization, the power infrastructure can be described as a network of nodes and links. The nodes represent the electrical buses where generators and loads are connected, while the links represent the transmission lines that interconnect the buses. This paper focuses mainly on a customized technique within GreenGrid that is designed to visually identify abnormal characteristics of the electricity infrastructure. In particular, we examine an extreme event that occurred within the Western United States power grid on August 10, 1996. We compare our study results with the conclusion of the post-disturbance analysis and find that many of the disturbance characteristics can be readily identified with the proper form of visualization. The paper includes a lessons learned discussion to evaluate the visualization application.

Model checking grid security  

Science Journals Connector (OSTI)

Grid computing is one of the leading forms of high performance computing. Security in the grid environment is a challenging issue that can be characterized as a complex system involving many subtleties that may lead designers into error. This is similar to what happens with security protocols where automatic verification techniques (specially model checking) have been proved to be very useful at design time. This paper proposes a formal verification methodology based on model checking that can be applied to host security verification for grid systems. The proposed methodology must take into account that a grid system can be described as a parameterized model, and security requirements can be described as hyperproperties. Unfortunately, both parameterized model checking and hyperproperty verification are, in general, undecidable. However, it has been proved that this problem becomes decidable when jobs have some regularities in their organization. Therefore, this paper presents a verification methodology that reduces a given grid system model to a model to which it is possible to apply a cutoff theorem (i.e., a requirement is satisfied by a system with an arbitrary number of jobs if and only if it is satisfied by a system with a finite number of jobs up to a cutoff size). This methodology is supported by a set of theorems, whose proofs are presented in this paper. The methodology is explained by means of a case study: the Condor system.

This report focuses on the initial phase of staff acquisition which was directed and administered by DOE NETL/ West Virginia under Project Officer Tom George. Using this CDP funding, we have developed the leadership and intellectual capacity for the SGIC. This was accomplished by investing (hiring) a core team of Smart Grid Systems engineering faculty focused on education, research, and innovation of a secure and smart grid infrastructure. The Smart Grid Integration Laboratory will be housed with the separately funded Integrid Laboratory as part of CSU??s overall Smart Grid Integration Center (SGIC). The period of performance of this grant was 10/1/2009 to 9/30/2011 which included one no cost extension due to time delays in faculty hiring. The Smart Grid Integration Laboratory??s focus is to build foundations to help graduate and undergraduates acquire systems engineering knowledge; conduct innovative research; and team externally with grid smart organizations. Using the results of the separately funded Smart Grid Workforce Education Workshop (May 2009) sponsored by the City of Fort Collins, Northern Colorado Clean Energy Cluster, Colorado State University Continuing Education, Spirae, and Siemens has been used to guide the hiring of faculty, program curriculum and education plan. This project develops faculty leaders with the intellectual capacity to inspire its students to become leaders that substantially contribute to the development and maintenance of Smart Grid infrastructure through topics such as: (1) Distributed energy systems modeling and control; (2) Energy and power conversion; (3) Simulation of electrical power distribution system that integrates significant quantities of renewable and distributed energy resources; (4) System dynamic modeling that considers end-user behavior, economics, security and regulatory frameworks; (5) Best practices for energy management IT control solutions for effective distributed energy integration (including security with the underlying physical power systems); (6) Experimental verification of effects of various arrangements of renewable generation, distributed generation and user load types along with conventional generation and transmission. Understanding the core technologies for enabling them to be used in an integrated fashion within a distribution network remains is a benefit to the future energy paradigm and future and present energy engineers.

H2 production based on RDG and assisted by a weak grid. System topology, operation and control  

Science Journals Connector (OSTI)

The Renewable Distributed Generation (RDG), such as production of electricity in the vicinity of the load, it is particularly beneficial when the distribution network is "weak" facing specific demands, as in hydrogen production systems connected to rural electrification networks. In these areas, the wind resource may be suitable for this type of generation. This work proposes the topology and the operation and control strategy for a hydrogen production station, "assisted" by a weak AC grid and "powered" by a variable speed wind turbine based on a three-phase double stator induction machine. The wind energy conversion is optimized through adequate control of the generator. The electrolyzer current is regulated for the maximum utilization of the generated power. The high-speed power fluctuations by turbulence are compensated through a controlled energy storage system based on a flywheel. In addition, the system configuration, its operation mode and control, and simulation results are presented.

A situational awareness framework for securing the smart grid using monitoring sensors and threat models  

Science Journals Connector (OSTI)

Security, access control and risk mitigation in the smart grid are matters of great impact for this important sector of the critical infrastructure. Situational awareness requires a means of aggregating information and presenting that information in a manner conducive to assessing risk. While major components of the electric power grid were traditionally deployed in physically isolated networks, they are now utilising IP-based, open, interconnected networks to transmit and manage the supervisory control and data acquisition (SCADA) messages. Unfortunately, SCADA protocols used for communications and the systems that implement those protocols were not originally designed with security in mind. Therefore, in order to enhance security and detect potential malicious behaviour, smart grid operators need detailed and accurate information about the status, integrity, configuration and network topology of SCADA devices as well as information about any threats that may impact the grid. This paper describes a comprehensive framework that provides situational awareness (SA) for SCADA devices and their operations in a smart grid environment. Situational awareness is achieved by processing information collected by monitoring sensors and understanding threats that may affect operations. The proposed framework employs a threat modelling methodology to support this mission.

PMU Placement for Enhancing Dynamic Observability of a Power Grid  

SciTech Connect (OSTI)

Power grids are operated in an increasingly complicated environment. However, operators lack effective and accurate tools for real-time monitoring and control of power systems. The U.S. Department of Energy, along with several utilities and system operators, is making a major $108 million investment in the Western Interconnection for phasor measurement unit (PMU) installation and phasor application development. This phasor measurement network opens up many opportunities for the estimation and prediction of power system states in real time, which enable operators to evaluate the system dynamic security in advance and allow them more time to respond to disturbances. Kalman filter based dynamic state estimation offers a solution suitable for this purpose. Our work indicates that the performance of Kalman filters in dynamic state estimation would degrade if PMU measurements cannot adequately capture the system dynamics. This paper develops a framework to identify how to place PMUs to improve dynamic observability of the power grid. Simulation results validate the concept, and the guidelines for PMU placement are derived.

Three-Phase Modular Cascaded H-Bridge Multilevel Inverter with Individual MPPT for Grid-Connected Photovoltaic Systems  

SciTech Connect (OSTI)

A three-phase modular cascaded H-bridge multilevel inverter for a grid-connected photovoltaic (PV) system is presented in this paper. To maximize the solar energy extraction of each PV string, an individual maximum power point tracking (MPPT) control scheme is applied, which allows the independent control of each dc-link voltage. PV mismatches may introduce unbalanced power supplied to the three-phase system. To solve this issue, a control scheme with modulation compensation is proposed. The three-phase modular cascaded multilevel inverter prototype has been built. Each H-bridge is connected to a 185 W solar panel. Simulation and experimental results are presented to validate the proposed ideas.

A novel multi-model neuro-fuzzy-based MPPT for three-phase grid-connected photovoltaic system  

SciTech Connect (OSTI)

This paper presents a novel methodology for Maximum Power Point Tracking (MPPT) of a grid-connected 20 kW photovoltaic (PV) system using neuro-fuzzy network. The proposed method predicts the reference PV voltage guarantying optimal power transfer between the PV generator and the main utility grid. The neuro-fuzzy network is composed of a fuzzy rule-based classifier and three multi-layered feed forwarded Artificial Neural Networks (ANN). Inputs of the network (irradiance and temperature) are classified before they are fed into the appropriated ANN for either training or estimation process while the output is the reference voltage. The main advantage of the proposed methodology, comparing to a conventional single neural network-based approach, is the distinct generalization ability regarding to the nonlinear and dynamic behavior of a PV generator. In fact, the neuro-fuzzy network is a neural network based multi-model machine learning that defines a set of local models emulating the complex and nonlinear behavior of a PV generator under a wide range of operating conditions. Simulation results under several rapid irradiance variations proved that the proposed MPPT method fulfilled the highest efficiency comparing to a conventional single neural network and the Perturb and Observe (P and O) algorithm dispositive.
