Integrating Variable Renewable Energy: Challenges and Solutions  

SciTech Connect (OSTI)

In the U.S., a number of utilities are adopting higher penetrations of renewables, driven in part by state policies. While power systems have been designed to handle the variable nature of loads, the additional supply-side variability and uncertainty can pose new challenges for utilities and system operators. However, a variety of operational and technical solutions exist to help integrate higher penetrations of wind and solar generation. This paper explores renewable energy integration challenges and mitigation strategies that have been implemented in the U.S. and internationally, including forecasting, demand response, flexible generation, larger balancing areas or balancing area cooperation, and operational practices such as fast scheduling and dispatch.

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

SciTech Connect (OSTI)

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

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

SciTech Connect (OSTI)

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

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

SciTech Connect (OSTI)

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

Solar Reserve Methodology for Renewable Energy Integration Studies Based on Sub-Hourly Variability Analysis: Preprint  

SciTech Connect (OSTI)

Increasing penetrations of wind a solar energy are raising concerns among electric system operators because of the variability and uncertainty associated with power sources. Previous work focused on the quantification of reserves for systems with wind power. This paper presents a new methodology that allows the determination of necessary reserves for high penetrations of photovoltaic (PV) power and compares it to the wind-based methodology. The solar reserve methodology is applied to Phase 2 of the Western Wind and Solar Integration Study. A summary of the results is included.

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

SciTech Connect (OSTI)

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

Use of Frequency Response Metrics to Assess the Planning and Operating Requirements for Reliable Integration of Variable Renewable Generation  

SciTech Connect (OSTI)

An interconnected electric power system is a complex system that must be operated within a safe frequency range in order to reliably maintain the instantaneous balance between generation and load. This is accomplished by ensuring that adequate resources are available to respond to expected and unexpected imbalances and restoring frequency to its scheduled value in order to ensure uninterrupted electric service to customers. Electrical systems must be flexible enough to reliably operate under a variety of"change" scenarios. System planners and operators must understand how other parts of the system change in response to the initial change, and need tools to manage such changes to ensure reliable operation within the scheduled frequency range. This report presents a systematic approach to identifying metrics that are useful for operating and planning a reliable system with increased amounts of variable renewable generation which builds on existing industry practices for frequency control after unexpected loss of a large amount of generation. The report introduces a set of metrics or tools for measuring the adequacy of frequency response within an interconnection. Based on the concept of the frequency nadir, these metrics take advantage of new information gathering and processing capabilities that system operators are developing for wide-area situational awareness. Primary frequency response is the leading metric that will be used by this report to assess the adequacy of primary frequency control reserves necessary to ensure reliable operation. It measures what is needed to arrest frequency decline (i.e., to establish frequency nadir) at a frequency higher than the highest set point for under-frequency load shedding within an interconnection. These metrics can be used to guide the reliable operation of an interconnection under changing circumstances.

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

Science Journals Connector (OSTI)

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

The RenewElec Project: Variable Renewable Energy and the Power System  

SciTech Connect (OSTI)

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

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.

Modelling of Integrated Renewable Energy System  

Science Journals Connector (OSTI)

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

Integrating Renewable Electricity on the Grid  

Science Journals Connector (OSTI)

The demand for carbon?free electricity is driving a growing movement of adding renewable energy to the grid. Renewable Portfolio Standards mandated by states and under consideration by the federal government envision a penetration of 20?30% renewable energy in the grid by 2020 or 2030. The renewable energy potential of wind and solar far exceeds these targets suggesting that renewable energy ultimately could grow well beyond these initial goals.

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.

Modeling renewable energy resources in integrated resource planning  

SciTech Connect (OSTI)

Including renewable energy resources in integrated resource planning (IRP) requires that utility planning models properly consider the relevant attributes of the different renewable resources in addition to conventional supply-side and demand-side options. Otherwise, a utility`s resource plan is unlikely to have an appropriate balance of the various resource options. The current trend toward regulatory set-asides for renewable resources is motivated in part by the perception that the capabilities of current utility planning models are inadequate with regard to renewable resources. Adequate modeling capabilities and utility planning practices are a necessary prerequisite to the long-term penetration of renewable resources into the electric utility industry`s resource mix. This report presents a review of utility planning models conducted for the National Renewable Energy Laboratory (NREL). The review examines the capabilities of utility planning models to address key issues in the choice between renewable resources and other options. The purpose of this review is to provide a basis for identifying high priority areas for advancing the state of the art.

The Western Wind and Solar Integration Study Phase 2 An examination of how wind and solar power affect operations, costs, and emissions from fossil-fueled generators The electric grid is a highly complex, interconnected machine. Changing one part of the grid can have consequences elsewhere. Adding variable renewable generation such as wind and solar power affects the operation of the other types of power plants, and adding high penetrations can induce cycling of fossil-fueled generators. Cycling leads to wear-and-tear costs and changes in emissions, but do those increases in costs and emissions from cycling negate the overall benefits of integrating renewables?

Chapter 1 - Energy Storage for Mitigating the Variability of Renewable Electricity Sources  

Science Journals Connector (OSTI)

Abstract Wind and solar power generation is growing quickly around the world, mainly to mitigate some of the negative environmental impacts of the electricity sector. However, the variability of these renewable sources of electricity poses technical and economical challenges when integrated on a large scale. Energy storage is being widely regarded as one of the potential solutions to deal with the variations of variable renewable electricity sources (VRES). This chapter presents an review of the state of technology, installations and some challenges of electrical energy storage (EES) systems. It particularly focuses on the applicability, advantages and disadvantages of various EES technologies for large-scale VRES integration. This chapter indicates that each challenge imposed by VRES requires a dierent set of EES characteristics to address the issue, and that there is no single EES technology that consistently outperforms the others in various applications. This chapter also discusses external factors, such as mineral availability and geographic limitations, that may aect the success of the widespread implementation of EES technologies.

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.

Integration of Variable Generation and Cost-Causation (Fact Sheet)  

SciTech Connect (OSTI)

Variable renewable energy generation sources, such as wind and solar energy, provide benefits such as reduced environmental impact, zero fuel consumption, and low and stable costs. Advances in both technologies can reduce capital costs and provide significant control capabilities. However, their variability and uncertainty - which change with weather conditions, time of day, and season - can cause an increase in power system operating costs compared to a fully controllable power plant. Although a number of studies have assessed integration costs, calculating them correctly is challenging because it is difficult to accurately develop a baseline scenario without variable generation that properly accounts for the energy value. It is also difficult to appropriately allocate costs given the complex, nonlinear interactions between resources and loads.

Generation and transmission expansion planning for renewable energy integration  

SciTech Connect (OSTI)

In recent years the expansion planning problem has become increasingly complex. As expansion planning (sometimes called composite or integrated resource planning) is a non-linear and non-convex optimization problem, researchers have traditionally focused on approximate models of power flows to solve the problem. The problem has also been split into generation expansion planning (GEP) and transmission network expansion planning (TNEP) to improve computational tractability. Until recently these approximations have produced results that are straight-forward to combine and adapt to the more complex and complete problem. However, the power grid is evolving towards a state where the adaptations are no longer easy (e.g. large amounts of limited control, renewable generation, comparable generation and transmission construction costs) and necessitates new approaches. Recent work on deterministic Discrepancy Bounded Local Search (DBLS) has shown it to be quite effective in addressing the TNEP. In this paper, we propose a generalization of DBLS to handle simultaneous generation and transmission planning.

Mills, Charles A. Goldman, Ryan H. Wiser, and Joseph H. Eto Pagination 76 Date Published 10/2011 Publisher LBNL City Berkeley Keywords demand response, electricity markets and policy group, energy analysis and environmental impacts department, renewable generation integration, smart grid Abstract The penetration of renewable generation technology (e.g., wind, solar) is expected to dramatically increase in the United States during the coming years as many states are implementing policies to expand this sector through regulation and/or legislation. It is widely understood, though, that large scale deployment of certain renewable energy sources, namely wind and solar, poses system integration challenges because of its variable and often times unpredictable production characteristics (NERC, 2009). Strategies that rely on existing thermal generation resources and improved wind and solar energy production forecasts to manage this variability are currently employed by bulk power system operators, although a host of additional options are envisioned for the near future. Demand response (DR), when properly designed, could be a viable resource for managing many of the system balancing issues associated with integrating large-scale variable generation (VG) resources (NERC, 2009). However, demand-side options would need to compete against strategies already in use or contemplated for the future to integrate larger volumes of wind and solar generation resources. Proponents of smart grid (of which Advanced Metering Infrastructure or AMI is an integral component) assert that the technologies associated with this new investment can facilitate synergies and linkages between demand-side management and bulk power system needs. For example, smart grid proponents assert that system-wide implementation of advanced metering to mass market customers (i.e., residential and small commercial customers) as part of a smart grid deployment enables a significant increase in demand response capability.1 Specifically, the implementation of AMI allows electricity consumption information to be captured, stored and utilized at a highly granular level (e.g., 15-60 minute intervals in most cases) and provides an opportunity for utilities and public policymakers to more fully engage electricity customers in better managing their own usage through time-based rates and near-real time feedback to customers on their usage patterns while also potentially improving the management of the bulk power system. At present, development of time-based rates and demand response programs and the installation of variable generation resources are moving forward largely independent of each other in state and regional regulatory and policy forums and without much regard to the complementary nature of their operational characteristics.2 By 2020, the electric power sector is expected to add ~65 million advanced meters3 (which would reach ~47% of U.S. households) as part of smart grid and AMI4 deployments (IEE, 2010) and add ~40-80 GW of wind and solar capacity (EIA, 2010). Thus, in this scoping study, we focus on a key question posed by policymakers: what role can the smart grid (and its associated enabling technology) play over the next 5-10 years in helping to integrate greater penetration of variable generation resources by providing mass market customers with greater access to demand response opportunities? There is a well-established body of research that examines variable generation integration issues as well as demand response potential, but the nexus between the two has been somewhat neglected by the industry. The studies that have been conducted are informative concerning what could be accomplished with strong broad-based support for the expansion of demand response opportunities, but typically do not discuss the many barriers that stand in the way of reaching this potential. This study examines how demand side resources could be used to integrate wind and solar resources in the bulk power system, identifies barriers that currently limit the use of demand side strategies, and suggests several factors that should be considered in assessing alternative strategies that can be employed to integrate wind and solar resources in the bulk power system. It is difficult to properly gauge the role that DR could play in managing VG integration issues in the near future without acknowledging and understanding the entities and institutions that govern the interactions between variable generation and mass market customers (see Figure ES-1). Retail entities, like load-serving entities (LSE) and aggregators of retail customers (ARC), harness the demand response opportunities of mass market customers through tariffs (and DR programs) that are approved by state regulatory agencies or local governing entities (in the case of public power). The changes in electricity consumption induced by DR as well as the changes in electricity production due to the variable nature of wind and solar generation technologies is jointly managed by bulk power system operators. Bulk power system operators function under tariffs approved by the Federal Energy Regulatory Commission (FERC) and must operate their systems in accordance with rules set by regional reliability councils. These reliability rules are derived from enforceable standards that are set by the North American Electric Reliability Corporation (NERC) and approved by federal regulators. Thus, the role that DR can play in managing VG integration issues is contingent on what opportunities state and local regulators are willing to approve and how customers' response to the DR opportunities can be integrated into the bulk power system both electrically (due to reliability rules) and financially (due to market rules).

Multi-Year Analysis of Renewable Energy Impacts in California: Results from the Renewable Portfolio Standards Integration Cost Analysis; Preprint  

SciTech Connect (OSTI)

California's Renewable Portfolio Standard (RPS, Senate Bill 1078) requires the state's investor-owned utilities to obtain 20% of their energy mix from renewable generation sources. To facilitate the imminent increase in the penetration of renewables, the California Energy Commission (CEC), in support of the California Public Utility Commission (CPUC), initiated a study of integration costs in the context of RPS implementation. This effort estimated the impact of renewable generation in the regulation and load-following time scales and calculated the capacity value of renewable energy sources using a reliability model. The analysis team, consisting of researchers from the National Renewable Energy Laboratory (NREL), Oak Ridge National Laboratory (ORNL) and the California Wind Energy Collaborative (CWEC), performed the study in cooperation with the California Independent System Operator (CaISO), the Pacific Gas and Electric Company (PG&E), and Southern California Edison (SCE). The study was conducted over three phases and was followed by an analysis of a multi-year period. This paper presents results from the multi-year analysis and the Phase III recommendations.

Electric vehicles and the electric grid: A review of modeling approaches, Impacts, and renewable energy integration  

Science Journals Connector (OSTI)

Electric vehicles (EVs) and renewable energy sources offer the potential to substantially decrease carbon emissions from both the transportation and power generation sectors of the economy. Mass adoption of \\{EVs\\} will have a number of impacts and benefits, including the ability to assist in the integration of renewable energy into existing electric grids. This paper reviews the current literature on EVs, the electric grid, and renewable energy integration. Key methods and assumptions of the literature are discussed. The economic, environmental and grid impacts of \\{EVs\\} are reviewed. Numerous studies assessing the ability of \\{EVs\\} to integrate renewable energy sources are assessed; the literature indicates that \\{EVs\\} can significantly reduce the amount of excess renewable energy produced in an electric system. Studies on wind–EV interaction are much more detailed than those on solar photovoltaics (PV) and EVs. The paper concludes with recommendations for future research.

Analysis and Synthesis of Load Forecasting Data for Renewable Integration Studies: Preprint  

SciTech Connect (OSTI)

As renewable energy constitutes greater portions of the generation fleet, the importance of modeling uncertainty as part of integration studies also increases. In pursuit of optimal system operations, it is important to capture not only the definitive behavior of power plants, but also the risks associated with systemwide interactions. This research examines the dependence of load forecast errors on external predictor variables such as temperature, day type, and time of day. The analysis was utilized to create statistically relevant instances of sequential load forecasts with only a time series of historic, measured load available. The creation of such load forecasts relies on Bayesian techniques for informing and updating the model, thus providing a basis for networked and adaptive load forecast models in future operational applications.

Renewable Resource Integration Project - Scoping Study of Strategic Transmission, Operations, and Reliability Issues  

SciTech Connect (OSTI)

California is on a path to increase utilization of renewable resources. California will need to integrate approximately 30,000 megawatts (MW) of new renewable generation in the next 20 years. Renewable resources are typically located in remote locations, not near the load centers. Nearly two/thirds or 20,000 MW of new renewable resources needed are likely to be delivered to Los Angeles Basin transmission gateways. Integration of renewable resources requires interconnection to the power grid, expansion of the transmission system capability between the backbone power grid and transmission gateways, and increase in delivery capacity from transmission gateways to the local load centers. To scope the transmission, operations, and reliability issues for renewables integration, this research focused on the Los Angeles Basin Area transmission gateways where most of new renewables are likely. Necessary actions for successful renewables integration include: (1) Expand Los Angeles Basin Area transmission gateway and nomogram limits by 10,000 to 20,000 MW; (2) Upgrade local transmission network for deliverability to load centers; (3) Secure additional storage, demand management, automatic load control, dynamic pricing, and other resources that meet regulation and ramping needed in real time operations; (4) Enhance local voltage support; and (5) Expand deliverability from Los Angeles to San Diego and Northern California.

Chapter 3 - Harnessing and Integrating Africa's Renewable Energy Resources  

Science Journals Connector (OSTI)

Abstract Africa’s long-term economic growth and competitiveness fundamentally depend on reliable access to energy services; yet, the population of Sub-Saharan Africa lags far behind the rest of the world in terms of access to electricity. Recent technological advancements as well as significant drops in associated costs present the African continent with a momentous opportunity to leapfrog to modern renewable energy. Although there is general recognition among African governments that renewable power provides huge opportunities given the continent’s enormous resources, the lack of coherent, consistent policies, technical skills, institutional capacity, infrastructure and financial incentives remains a major barrier for wide-spread adoption. In this chapter we review i. the significant role of renewables in mitigating Africa’s key energy challenges; and ii. the importance of coordinated efforts from all angles in guiding Africa towards a cleaner, more sustainable energy future.

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

Science Journals Connector (OSTI)

Abstract This paper provides a comprehensive discussion of the market value of variable renewable energy (VRE). The inherent variability of wind speeds and solar radiation affects the price that VRE generators receive on the market (market value). During windy and sunny times the additional electricity supply reduces the prices. Because the drop is larger with more installed capacity, the market value of VRE falls with higher penetration rate. This study aims to develop a better understanding on how the market value with penetration, and how policies and prices affect the market value. Quantitative evidence is derived from a review of published studies, regression analysis of market data, and the calibrated model of the European electricity market EMMA. We find the value of wind power to fall from 110% of the average power price to 50–80% as wind penetration increases from zero to 30% of total electricity consumption. For solar power, similarly low value levels are reached already at 15% penetration. Hence, competitive large-scale renewable deployment will be more difficult to accomplish than as many anticipate.

This CERI report aims to provide an introductory overview of key regulatory issues associated with the deployment of renewable energy -- particularly variable renewable energy (VRE) sources such wind and solar power. The report draws upon the research and experiences from various international contexts, and identifies key ideas that have emerged from the growing body of VRE deployment experience and regulatory knowledge. The report assumes basic familiarity with regulatory concepts, and although it is not written for a technical audience, directs the reader to further reading when available. VRE deployment generates various regulatory issues: substantive, procedural, and public interest issues, and the report aims to provide an empirical and technical grounding for all three types of questions as appropriate.

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

Science Journals Connector (OSTI)

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

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

Science Journals Connector (OSTI)

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

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.

Dynamic Analysis of Hybrid Energy Systems under Flexible Operation and Variable Renewable Generation -- Part I: Dynamic Performance Analysis and Part II: Dynamic Cost  

SciTech Connect (OSTI)

Dynamic analysis of hybrid energy systems (HES) under flexible operation and variable renewable generation is considered in order to better understand various challenges and opportunities associated with the high system variability arising from the integration of renewable energy into the power grid. Unique consequences are addressed by devising advanced HES solutions in which multiple forms of energy commodities, such as electricity and chemical products, may be exchanged. Dynamic models of various unit operations are developed and integrated within two different HES options. One HES option, termed traditional, produces electricity only and consists of a primary heat generator (PHG) (e.g., a small modular reactor), a steam turbine generator, a wind farm, and a battery storage. The other HES option, termed advanced, includes not only the components present in the traditional option but also a chemical plant complex to repurpose excess energy for non-electricity services, such as for the production of chemical goods (e.g., transportation fuel). In either case, a given HES is connected to the power grid at a point of common coupling and requested to deliver a certain electricity generation profile as dictated by a regional power grid operator based on a predicted demand curve. Dynamic analysis of these highly-coupled HES are performed to identify their key dynamical properties and limitations and to prescribe solutions for best managing and mitigating the high variability introduced from incorporating renewable energy into the energy mix. A comparative dynamic cost analysis is also conducted to determine best HES options. The cost function includes a set of metrics for computing fixed costs, such as fixed operations and maintenance (O&M) and overnight capital costs, and also variable operational costs, such as cost of variability, variable O&M cost, and cost of environmental impact, together with revenues. Assuming different options for implementing PHG (e.g., natural gas, coal, nuclear), preliminary results identify the level of renewable penetration at which a given advanced HES option (e.g., a nuclear hybrid) becomes increasingly more economical than a traditional electricity-only generation solution. Conditions are also revealed under which carbon resources may be better utilized as carbon sources for chemical production rather than as combustion material for electricity generation.

Evaluation of energy storage technologies for integration with renewable electricity: Quantifying expert opinions  

Science Journals Connector (OSTI)

Solving climate change and the associated need for increasing renewable energy supply make energy storage a critical technological component of the future energy landscape. Research to build more reliable and cost-effective energy storage technologies is now on the rise. As a result, many new technologies and applications are evolving and competing. This paper presents a method to evaluate and select energy storage technologies for investor-owned or public utilities. For this purpose, energy storage applications which could benefit wind power in the Pacific Northwest region of the United States are identified through internal interviews and surveys with experts at the federal wholesale power marketing agency in Portland, Oregon. The study employs a technology evaluation process integrating fuzzy Delphi method, analytic hierarchy process and fuzzy consistent matrix. The result shows that compressed air storage is the most promising technology for sustainable growth of renewable energy in the region.

Energy efficiency and renewable energy integration in data centres. Strategies and modelling review  

Science Journals Connector (OSTI)

Abstract The continuous growth in size, complexity and energy density of data centres due to the increasing demand for storage, networking and computation has become a worldwide energetic problem. The emergent awareness of the negative impact that the uncontrolled energy consumption has on natural environment, the predicted limitation of fossil fuels production in the upcoming decades and the growing associated costs have strongly influenced the energy systems engineering work in the last decades. Therefore, the implementation of well known and advanced energy efficiency measures to reduce data centres energy demand play an important role not only to a supportable growth but also to reduce its operational costs. The carbon footprint is greatly influenced by the energy sources used. Therefore, there have been recent efforts to exploit and reuse or combine green energy sources in data centres to lower brown energy consumption and CO2 emissions. This paper presents a comprehensible overview of the current data centre infrastructure and summarizes a number of currently available energy efficiency strategies and renewable energy integration into data centres and its characterization using numerical models. Moreover it would be necessary to develop dynamic models and metrics for properly understand and quantify the energy consumption and the benefits of applying the incoming energy efficiency strategies and renewable energy sources in the data centres. Thus, the researches or investors will be able to compare with reliability the different data centre designs and choose the best option depending on the renewable energy sources and capital available.

High Renewable Generation High Renewable Generation Feasibility of Higher Levels of Renewable Electricity Deployment As requirements for renewable electricity generation increase, with some states now requiring as much as 30% renewables in their renewable portfolio standards (RPS), the question arises: how much can renewables contribute to future electricity demand? NREL's grid integration studies use state-of-the-art modeling and analysis techniques to evaluate the operational and infrastructure impacts of higher wind and solar penetrations at regional and national scales. NREL's grid integration studies show that: The U.S. electric system is operable with 20%-50% variable generation from wind and solar power in the regional and national scenarios examined to date.

Chapter 6 - Case Study–Renewable Integration: Flexibility Requirement, Potential Overgeneration, and Frequency Response Challenges  

Science Journals Connector (OSTI)

Abstract The ISO analysis has shown that variability and uncertainty of predicting renewable production do pose some operational challenges. The output from renewable production can increase and drop-off dramatically by hundreds of megawatts in just a matter of 30 minutes, which would require more flexible resources into the ISO’s generation mix. This need is compounded as California policy on once-through-cooling resources may result in the shutting-down of approximately 12,000 MW of conventional resources over the next 7 years. Managing a more complex grid during this transitional period, ensuring the right mix of resource are available in real-time to maintain reliability and meeting mandatory control performance standards become more of a challenge. As a result of this fleet evolution, there are real opportunities to design the fleet make up and incentivize new capability from a broad range of source including 1) demand response, 2) the variable resources themselves, 3) regional coordination, 4) storage and 5) hydro, in addition to the conventional resources to optimize meeting the policy objectives while ensuring basic grid reliability is maintained. On some days during the spring months, the ISO’s net-load is expected to drop to levels that encroach on non-dispatchable production levels when solar and wind production is high and system demand is low. Thus, in the middle of the day when the sun is shining there would be less need for additional supply resources. As time progresses to the evening hours towards sunset, there is an immediate need to replace the solar generation in addition to meeting increase in consumer demand. A complicating factor is that many of the conventional resources that could replace the solar generation must start prior to this significant ramp. These resources often require several hours to a day or more to fully come on line, which can cause more generation to be on line than consumer demand causing over generation conditions. Under existing arrangement solar (and wind) resources have limited provisions to be curtailed. Therefore as most conventional generators require this "start-up" time to reach their minimum load levels, at times the minimum energy on conventional resources may not be needed but the units cannot be shut down because the resources are needed later on during the day. There is little that a grid operator can do to accommodate this excess generation condition as supply and demand must match instantaneously. As over generation condition increase there would be a need to increase regional coordination by forming an Energy Imbalance Market to help mitigate the potential for over-generation conditions. Other solutions such as advanced demand response and storage may also be innovative solutions in the future to help balance the system during range of expected daily imbalance conditions. In addition, incentivizing the renewable resources to be flexible themselves may also be part of the solution. To reliably operate the system, the ISO is advocating for resource flexibility that can start up and provide its maximum energy quickly. An additional condition requiring flexible resources is the intra-hour variability of passing clouds or storm conditions that can interrupt the output of the wind and solar generation resources. Another operational condition that must be met in real-time is the need to ensure sufficient inertia and frequency response exists in the system. Today, conventional resources because of their rotating mass and ability to respond to changes in frequency provide a reliable shock absorber to disturbance events. As such resources are displaced by renewable resources, it will be important to ensure the system is able to respond to dynamic events in a stable manner. Again in this area, opportunities exist that would allow renewable resources to be part of the solution. There are also opportunities to make wider use of demand response and smart technologies to provide this primary frequency response capability.

Wear-and-Tear Costs and Emissions Wear-and-Tear Costs and Emissions Impacts of Cycling and Ramping Are Relatively Small The Western Wind and Solar Integration Study (WWSIS) is one of the largest regional wind and solar integration studies to date. It examines the operational impact of up to 35% penetration of wind, photovoltaic (PV), and concentrating solar power (CSP) energy on the electric power system. The goal is to understand the effects of and investigate mitigation options for the variability and uncertainty of wind and solar. Phase 1 Research Phase 1 of the Western Wind and Solar Integration Study (WWSIS1) found no technical barriers to the integration of high penetrations of wind and solar power in the Western Interconnection power system if certain changes to opera- tional practices are made.

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

Science Journals Connector (OSTI)

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

Solar and wind resource complementarity: Advancing options for renewable electricity integration in Ontario, Canada  

Science Journals Connector (OSTI)

In Ontario (Canada), the integration of renewable power is a priority policy goal. Since 2004, the circumstances under which the integration of renewable power is evaluated have changed due to successive changes in price as well as concerns that its over-production may add to grid congestion. This research investigates the value of increasing complementarity (both proximate and geographically dispersed) of wind and solar resources as a means by which electricity planners and researchers might advance electricity sustainability in Ontario. More specifically, this paper asks the following questions: 1) Does the combination of solar and wind resources in selected locations in Ontario serve to ‘smooth out’ power production, i.e., decrease instances of both high and low values, as compared to either resource producing individually? 2) Can this ‘smoothness’ be further improved by dispersing these resources geographically amongst locations? and 3) Does increasing the number of locations with solar and wind resources further ‘smooth out’ power production? Three years (2003–2005) of synchronous, hourly measurements of solar irradiance and wind speeds from Environment Canada’s Canadian Weather Energy and Engineering Data Sets (CWEEDS) are used to derive dimensionless indices for four locations in Ontario (Toronto, Wiarton, Sault Ste. Marie and Ottawa). These indices are used to develop three transparent and accessible methods of analysis: (1) graphical representation; (2) percentile ranking; and (3) using a theoretical maximum as a proxy for capacity. The article concludes that the combination of solar and wind within locations and amongst two locations improves ‘smoothness’ in power production, as compared to when each resource is produced on its own; moreover, it is further improved once more than two resources and two locations are combined. However, there is neither further benefit, nor drawback, associated with the geographic dispersion of complementarity between solar in one location and wind in another, when compared to both resources in one location.

GENI Project: The CRA team is developing control technology to help grid operators more actively manage power flows and integrate renewables by optimally turning on and off entire power lines in coordination with traditional control of generation and load resources. The control technology being developed would provide grid operators with tools to help manage transmission congestion by identifying the facilities whose on/off status must change to lower generation costs, increase utilization of renewable resources and improve system reliability. The technology is based on fast optimization algorithms for the near to real-time change in the on/off status of transmission facilities and their software implementation.

Impact of Generator Flexibility on Electric System Costs and Integration of Renewable Energy  

SciTech Connect (OSTI)

Flexibility of traditional generators plays an important role in accommodating the increased variability and uncertainty of wind and solar on the electric power system. Increased flexibility can be achieved with changes to operational practices or upgrades to existing generation. One challenge is in understanding the value of increasing flexibility, and how this value may change given higher levels of variable generation. This study uses a commercial production cost model to measure the impact of generator flexibility on the integration of wind and solar generators. We use a system that is based on two balancing areas in the Western United States with a range of wind and solar penetrations between 15% and 60%, where instantaneous penetration of wind and solar is limited to 80%.

A methodology for analysis of impacts of grid integration of renewable energy  

Science Journals Connector (OSTI)

Present electricity grids are predominantly thermal (coal, gas) and hydro based. Conventional power planning involves hydro-thermal scheduling and merit order dispatch. In the future, modern renewables (hydro, solar and biomass) are likely to have a significant share in the power sector. This paper presents a method to analyse the impacts of renewables in the electricity grid. A load duration curve based approach has been developed. Renewable energy sources have been treated as negative loads to obtain a modified load duration curve from which capacity savings in terms of base and peak load generation can be computed. The methodology is illustrated for solar, wind and biomass power for Tamil Nadu (a state in India). The trade-offs and interaction between renewable sources are analysed. The impacts on capacity savings by varying the wind regime have also been shown. Scenarios for 2021–22 have been constructed to illustrate the methodology proposed. This technique can be useful for power planners for an analysis of renewables in future electricity grids.

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 4966 TWh 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 784.38 TWh and reduce CO2 emission by 999.57 million tons during 2013–2025, since the multi-regional power operation can integrate more than 488.30 TWh 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.

A Unit Commitment Model with Demand Response for the Integration of Renewable Energies  

E-Print Network [OSTI]

The output of renewable energy fluctuates significantly depending on weather conditions. We develop a unit commitment model to analyze requirements of the forecast output and its error for renewable energies. Our model obtains the time series for the operational state of thermal power plants that would maximize the profits of an electric power utility by taking into account both the forecast of output its error for renewable energies and the demand response of consumers. We consider a power system consisting of thermal power plants, photovoltaic systems (PV), and wind farms and analyze the effect of the forecast error on the operation cost and reserves. We confirm that the operation cost was increases with the forecast error. The effect of a sudden decrease in wind power is also analyzed. More thermal power plants need to be operated to generate power to absorb this sudden decrease in wind power. The increase in the number of operating thermal power plants within a short period does not affect the total opera...

Quantifiably secure power grid operation, management, and evolution : a study of uncertainties affecting the grid integration of renewables.  

SciTech Connect (OSTI)

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

A unit commitment study of the application of energy storage toward the integration of renewable generation  

Science Journals Connector (OSTI)

To examine the potential benefits of energy storage in the electric grid a generalized unit commitment model of thermal generating units and energy storage facilities is developed. Three different storage scenarios were tested—two without limits to total storage assignment and one with a constrained maximum storage portfolio. Given a generation fleet based on the City of Austin’s renewable energy deployment plans results from the unlimited energy storage deployment scenarios studied show that if capital costs are ignored large quantities of seasonal storage are preferred. This operational approach enables storage of plentiful wind generation during winter months that can then be dispatched during high cost peak periods in the summer. These two scenarios yielded $70 million and $94 million in yearly operational cost savings but would cost hundreds of billions to implement. Conversely yearly cost reductions of $40 million can be achieved with one compressed air energy storage facility and a small set of electrochemical storage devices totaling 13?GWh of capacity. Similarly sized storage fleets with capital costs service lifetimes and financing consistent with these operational cost savings can yield significant operational benefit by avoiding dispatch of expensive peaking generators and improving utilization of renewable generation throughout the year. Further study using a modified unit commitment model can help to clarify optimal storage portfolios reveal appropriate market participation approaches and determine the optimal siting of storage within the grid.

Software Based Barriers To Integration Of Renewables To The Future Distribution Grid  

SciTech Connect (OSTI)

The future distribution grid has complex analysis needs, which may not be met with the existing processes and tools. In addition there is a growing number of measured and grid model data sources becoming available. For these sources to be useful they must be accurate, and interpreted correctly. Data accuracy is a key barrier to the growth of the future distribution grid. A key goal for California, and the United States, is increasing the renewable penetration on the distribution grid. To increase this penetration measured and modeled representations of generation must be accurate and validated, giving distribution planners and operators confidence in their performance. This study will review the current state of these software and modeling barriers and opportunities for the future distribution grid.

Renewable energy and smart grid principles integration into campus-wide energy strategy at the University of New Mexico  

Science Journals Connector (OSTI)

With a significant percentage of Renewable Energy resources already installed and operational, the University of New Mexico (UNM) campus is identified as an excellent candidate for the implementation of Demand-Response strategies integrated with a modern grid management system. An Energy Control and Management System makes it possible for UNM campus to respond to grid signals in a centrally managed manner, although individual building control systems still perform local energy management functions. This hierarchical response strategy is a model for future grid-interoperable entities of all sizes. We address the existing potential for the UNM campus to interoperate with the outside world and the possibility of altering the electricity use based on external requests from the grid. We also identify infrastructure and information technology improvements that would result in a substantially increased level of interoperability.

DOE DE-FE0001888 Award, Phase 2, funded research, development, and deployment (RD&D) of Phycal’s pilot-scale, algae to biofuels, bioproducts, and processing facility in Hawai’i. Phycal’s algal-biofuel and bioproducts production system integrates several novel and mature technologies into a system that captures and reuses industrially produced carbon dioxide emissions, which would otherwise go directly to the atmosphere, for the manufacture of renewable energy products and bioproducts from algae (note that these algae are not genetically engineered). At the end of Phase 2, the project as proposed was to encompass 34 acres in Central Oahu and provide large open ponds for algal mass culturing, heterotrophic reactors for the Heteroboost™ process, processing facilities, water recycling facilities, anaerobic digestion facilities, and other integrated processes. The Phase 2 award was divided into two modules, Modules 1 & 2, where the Module 1 effort addressed critical scaling issues, tested highest risk technologies, and set the overall infrastructure needed for a Module 2. Phycal terminated the project prior to executing construction of the first Module. This Final Report covers the development research, detailed design, and the proposed operating strategy for Module 1 of Phase 2.

Renewable energy-driven desalination technologies: A comprehensive review on challenges and potential applications of integrated systems  

Science Journals Connector (OSTI)

Abstract Despite the tremendous improvements in conventional desalination technologies, its wide use is still limited due primarily to high energy requirements which are currently met with expensive fossil fuels. The use of alternative energy sources is essential to meet the growing demand for water desalination. In the last few decades a lot of effort has being directed in the use of different renewable energy (RE) sources to run desalination processes. However, the expansion of these efforts towards larger scale plants is hampered by several techno-economic challenges. Several medium-scale RE-driven desalination plants have been installed worldwide. Nevertheless, most of these plants are connected to the electrical grid to assure a continuous energy supply for stable operation. Furthermore, RE is mostly used to produce electric power which can be used to run desalination systems. This review paper focuses on an integrated approach in using RE-driven with an emphasis on solar and geothermal desalination technologies. Innovative and sustainable desalination processes which are suitable for integrated RE systems are presented. An assessment of the benefits of these technologies and their limitations are also discussed.

Wind and Solar Power- Wind and Solar Power- Induced Cycling on Wear-and-Tear Costs and Emissions Results From the Western Wind and Solar Integration Study Phase 2 The electric grid is a highly complex, interconnected machine. Changing one part of the grid can have consequences elsewhere. Adding variable renewable generation such as wind and solar power affects the operation of conventional power plants, and adding high penetrations can induce cycling of fossil-fueled generators. Cycling leads to wear-and-tear costs and changes in emissions. Phase 2 of the Western Wind and Solar Integration Study (WWSIS-2) was initiated to determine the wear-and-tear costs and emissions impacts of cycling and to simulate grid operations to investigate the detailed impact of wind and solar power on

Transforming our Nation's Transforming our Nation's Energy System With all the benefits associated with renewable energy, why hasn't the grid already been modernized to accommodate these clean sources of energy? The short answer is: Megawatt-scale integration is hard to find. Our nation's existing power grid is crucial to our way of life and cannot be shut down, overhauled, and started back up again. Yet, critical to moving clean energy technologies onto the electrical grid is the ability to carry out research, development, and megawatt-scale testing of the complex integrated systems, devices, and concepts of future electric supply and demand systems.

Renewed activity from the X-ray transient SAXJ 1810.8-2609 with INTEGRAL  

E-Print Network [OSTI]

We report on the results of INTEGRAL observations of the neutron star low mass X-ray binary SAX J1810.8-2609 during its latest active phase in August 2007. The current outburst is the first one since 1998 and the derived luminosity is 1.1-2.6x10^36 erg s-1 in the 20-100 keV energy range. This low outburst luminosity and the long-term time-average accretion rate of ~5x10^-12Msolar/yr suggest that SAXJ 1810.8-2609 is a faint soft X-ray transient. During the flux increase, spectra are consistent with a thermal Comptonization model with a temperature plasma of ~23-30 keV and an optical depth of ~1.2-1.5, independent from luminosity of the system. This is a typical low hard spectral state for which the X-ray emission is attributed to the upscattering of soft seed photons by a hot, optically thin electron plasma. During the decay, spectra have a different shape, the high energy tail being compatible with a single power law. This confirm similar behavior observed by BeppoSAX during the previous outburst, with absence of visible cutoff in the hard X-ray spectrum. INTEGRAL/JEM-X instrument observed four X-ray bursts in Fall 2007. The first one has the highest peak flux (~3.5Crab in 3--25 keV) giving an upper limit to the distance of the source of about 5.7 kpc, for a LEdd~3.8x10^38 erg s^-1. The observed recurrence time of ~1.2 days and the ratio of the total energy emitted in the persistent flux to that emitted in the bursts (~73) allow us to conclude that the burst fuel was composed by mixed hydrogen and helium with X>0.4.

Integrating VAV zone requirements with supply fan operation. [Variable Air Volume  

SciTech Connect (OSTI)

The use of communicating direct digital controls (DDC) with distributed intelligence offers new opportunities for energy conservation while maintaining occupant comfort in commercial buildings. Integrating control within a single DDC panel improves performance. Integrating control by communications between multiple controllers can further enhance system operation. One example is a DDC static pressure reset strategy for supply fan operation in variable air volume (VAV) supply air distribution systems. This strategy integrates the requirements of the VAV terminal units serving the building zones to minimize fan energy use. This article describes terminal unit operation, supply fan control, concurrent polling, operational data and power savings.

Integral variable structure current control of DFIG-based wind turbines near cut-in speed  

Science Journals Connector (OSTI)

Based on the grid voltage orientated vector control technique, a novel integral variable structure controller for current control of variable speed doubly fed induction generator (DFIG) wind turbines near cut-in wind speed is proposed. The proposed current controller can not only ensure generators' safe cut-in switches to the grid, but also maximum energy capture after switch motion without any regulations. By these, simulations of a 1.5 MW DFIG-based wind turbine near cut-in wind speed are separately conducted under integral variable structure control (IVSC) and PI control. The results show that IVSC strategy, which gives better dynamic response, less static error, smaller controller output dithering, stronger global robustness against generator parameters uncertainty and the grid voltage fluctuation, as well as needless controller regulation after cutting-in the grid, obviously preponderates over traditional PI control for DFIG-based wind turbines near cut-in speed.

Mass Market Demand Response and Variable Generation Integration Issues: A Scoping Study  

SciTech Connect (OSTI)

This scoping study focuses on the policy issues inherent in the claims made by some Smart Grid proponents that the demand response potential of mass market customers which is enabled by widespread implementation of Advanced Metering Infrastructure (AMI) through the Smart Grid could be the “silver bullet” for mitigating variable generation integration issues. In terms of approach, we will: identify key issues associated with integrating large amounts of variable generation into the bulk power system; identify demand response opportunities made more readily available to mass market customers through widespread deployment of AMI systems and how they can affect the bulk power system; assess the extent to which these mass market Demand Response (DR) opportunities can mitigate Variable Generation (VG) integration issues in the near-term and what electricity market structures and regulatory practices could be changed to further expand the ability for DR to mitigate VG integration issues over the long term; and provide a qualitative comparison of DR and other approaches to mitigate VG integration issues.

Role of Energy Storage with Renewable Electricity Generation  

SciTech Connect (OSTI)

Renewable energy sources, such as wind and solar, have vast potential to reduce dependence on fossil fuels and greenhouse gas emissions in the electric sector. Climate change concerns, state initiatives including renewable portfolio standards, and consumer efforts are resulting in increased deployments of both technologies. Both solar photovoltaics (PV) and wind energy have variable and uncertain (sometimes referred to as intermittent) output, which are unlike the dispatchable sources used for the majority of electricity generation in the United States. The variability of these sources has led to concerns regarding the reliability of an electric grid that derives a large fraction of its energy from these sources as well as the cost of reliably integrating large amounts of variable generation into the electric grid. In this report, we explore the role of energy storage in the electricity grid, focusing on the effects of large-scale deployment of variable renewable sources (primarily wind and solar energy).

Estimating the Effect of Domestic Load and Renewable Supply Variability on Battery Capacity Requirements for Decentralized Microgrids  

Science Journals Connector (OSTI)

Abstract Large battery banks are a commonly considered alternative for local storage of volatile energy supply in decentralized grid management. In this paper the hypothetical case of an isolated community of 15 houses with direct access to a nearby set of wind turbines and a backup grid connection (e.g. ex-urban hamlet) is being considered. The question arises as to what size of battery, relative to household average daily consumption, should be installed in order to avoid excessively fast aging of said battery bank, i.e. to avoid the need to replace it faster than standard expected battery lifetime. The basic technology of the batteries addressed in this study is lithium ion phosphate. A dynamic modeling process of aging is implemented, along with realistic wind power data and a stochastic model of domestic load, with variable morning/evening peaks, weekend and seasonal effects. It was found that simulations using domestic load profiles and variability predict a significant reduction in expected battery state of health, for comparable average loads, than standard load cycles used for industrial testing, and that increased variability in average domestic load has a minor effect on the speed of state of health reduction. Furthermore a region of high sensitivity to overall battery bank size can be observed, which subsides over approx. 200 hours of average household consumption.

Such models are usually nonintegrable with solutions found numerically or perturbatively. We construct a class of VMSG models, integrable at both the classical and the quantum levels with exact soliton solutions, which can accelerate and change their shape, width, and amplitude simulating realistic inhomogeneous systems at certain limits.

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

Science Journals Connector (OSTI)

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

Climate change mitigation with integration of renewable energy resources in the electricity grid of New South Wales, Australia  

Science Journals Connector (OSTI)

Abstract The implementation of climate change mitigation strategies may significantly affect the current practices for electricity network operation. Increasing penetration of renewable energy generation technologies into electricity networks is one of the key mitigation strategies to achieve greenhouse gas emission reduction targets. Additional climate change mitigation strategies can also contribute to emission reduction thereby supplementing the renewable energy generation participation, which may be limited due to technical constraints of the network. In this paper, the penetration requirements for different renewable energy generation resources are assessed while concurrently examining other mitigation strategies to reduce overall emissions from electricity networks and meet requisite targets. The impacts of climate change mitigation strategies on the demand and generation mix are considered for facilitating the penetration of renewable generation. New climate change mitigation indices namely change in average demand, change in peak demand, generation flexibility and generation mix have been proposed to measure the level of emission reduction by incorporating different mitigation strategies. The marginal emissions associated with the individual generation technologies in the state of New South Wales (NSW) are modelled and the total emissions associated with the electricity grid of NSW are evaluated.

Modeling for System Integration Studies (Presentation)  

SciTech Connect (OSTI)

This presentation describes some the data requirements needed for grid integration modeling and provides real-world examples of such data and its format. Renewable energy integration studies evaluate the operational impacts of variable generation. Transmission planning studies investigate where new transmission is needed to transfer energy from generation sources to load centers. Both use time-synchronized wind and solar energy production and load as inputs. Both examine high renewable energy penetration scenarios in the future.

Chapter 8 - Advances in Market Management Solutions for Variable Energy Resources Integration  

Science Journals Connector (OSTI)

Abstract Integration of more and more Variable Energy Resources (VER) into the system has introduced new challenges to grid and market operations. This chapter first provides an overview of wholesale electricity markets and market management systems. The intermittent nature of VER’s increases the need for system ramping capability in real-time balancing market, and causes issues in long term market pricing and resource adequacy. Enhancements are being made in both market design and market analytical tools in terms of managing operational uncertainties introduced by VER integration. The rest of the chapter focuses on two areas of market enhancement. The first one is the idea to establish a ramp market in real-time balancing operation to create the right market incentives for resources to provide enough ramping energy to compensate VER volatility. The second topic is to manage short-term VER uncertainty by applying robust optimization to look-ahead unit commitment.

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

Science Journals Connector (OSTI)

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

Integrability study on a generalized (2+1)-dimensional variable-coefficient Gardner model with symbolic computation  

SciTech Connect (OSTI)

Gardner model describes certain nonlinear elastic structures, ion-acoustic waves in plasmas, and shear flows in ocean and atmosphere. In this paper, by virtue of the computerized symbolic computation, the integrability of a generalized (2+1)-dimensional variable-coefficient Gardner model is investigated. Painleve integrability conditions are derived among the coefficient functions, which reduce all the coefficient functions to be proportional only to {gamma}(t), the coefficient of the cubic nonlinear term u{sup 2}u{sub x}. Then, an independent transformation of the variable t transforms the reduced {gamma}(t)-dependent equation into a constant-coefficient integrable one. Painleve test shows that this is the only case when our original generalized (2+1)-dimensional variable-coefficient Gardner model is integrable.

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

Computer Models Computer Models Integrate Wind Turbines with Floating Platforms Far off the shores of energy-hungry coastal cities, powerful winds blow over the open ocean, where the water is too deep for today's seabed-mounted offshore wind turbines. For the United States to tap into these vast offshore wind energy resources, wind turbines must be mounted on floating platforms to be cost effective. Researchers at the National Renewable Energy Laboratory (NREL) are supporting that development with computer models that allow detailed analyses of such floating wind turbines. Coupling wind turbines and floating platforms requires complex computer models. Land- based wind turbines are designed and analyzed using simulation tools, called computer-aided engineering (CAE) design tools, that are capable of predicting a design's dynamic response to

Integration of renewable energy in microgrids coordinated with demand response resources: Economic evaluation of a biomass gasification plant by Homer Simulator  

Science Journals Connector (OSTI)

Abstract This paper deals with how demand response can contribute to the better integration of renewable energy resources such as wind power, solar, small hydro, biomass and CHP. In particular, an economic evaluation performed by means of the micro-power optimization model HOMER Energy has been done, considering a micro-grid supplied by a biomass gasification power plant, operating isolated to the grid and in comparison with other generation technologies. Different scenarios have been simulated considering variations in the power production of the gasified biomass generator and different solutions to guarantee the balance generation/consumption are analyzed, demonstrating as using demand response resources is much more profitable than producing this energy by other conventional technologies by using fossil fuels.

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

SciTech Connect (OSTI)

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

Market Designs for High Levels of Variable Generation: Preprint  

SciTech Connect (OSTI)

Variable renewable generation is increasing in penetration in modern power systems, leading to higher variability in the supply and price of electricity as well as lower average spot prices. This raises new challenges, particularly in ensuring sufficient capacity and flexibility from conventional technologies. Because the fixed costs and lifetimes of electricity generation investments are significant, designing markets and regulations that ensure the efficient integration of renewable generation is a significant challenge. This papers reviews the state of play of market designs for high levels of variable generation in the United States and Europe and considers new developments in both regions.

In fact, WIPP is striving to take advantage of its abundance of sunshine and wind. The Department of Energy's Office of Environmental Management has created what is being called the Energy Park Initiative (EPI). This initiative's goal is to convert DOE facilities into assets by focusing on providing solutions for renewable energy technologies. WIPP, which has always been a DOE leader in terms of safety, has set the additional goal of trying to become the first DOE site operating with 100 percent clean energy. A team, consisting of representatives from CBFO, WTS, Sandia National Laboratories, Los Alamos National Laboratory, New Mexico State University, Texas Tech, the Carlsbad community and area utilities, have come up with several potential solutions.

PUEBLO OF ZIA RENEWABLE ENERGY DEVELOPMENT FEASIBILITY STUDY  

SciTech Connect (OSTI)

The Pueblo of Zia will conduct a comprehensive feasibility study for best-use application(s) for development of renewable energy resources on its tribally held TRUST lands (i.e., Trust Lands of Zia Indian Reservation). The feasibility study is essential for determining the technical and economic viability of a future renewable project(s) on Zia tribal lands, including the potential economic and environmental benefits for the Tribe. Project Objectives: The feasibility study is essential for determining the technical and economic viability of future renewable project(s) on Zia tribal lands, including the potential economic and environmental benefits for the Tribe to: 1. Provide a balanced local renewable power supply for Zia Pueblo, its members, tribal offices, schools and buildings, and businesses on tribal lands 2. Provide a firm power supply for export and commercial market distribution 3. Provide economic development for the Tribe and its members, including job training and creation, each in accordance with the goals and objectives as conveyed by the Pueblo of Zia Tribal Council, Tribal Administration, and outlined in The Pueblo of Zia Comprehensive Plan and Pueblo of Zia — Zia Enterprise Zone Master Plan. A key goal of the study is to analyze the integrated development of solar, geothermal, and wind renewable energy resources at Zia Pueblo, with added potential to combine gas-fired generation to accomplish energy firming. Geothermal offers a base load source of energy, providing power continuously for end users. Wind and solar offer intermediate and peaking sources of energy, which can be harvested throughout the day, with periods of variable but predicable output. Variability will be managed in an integrated manner, using Zia Pueblo's combined renewable resources to generate high-quality power. Tasks are intended to collect, catalog, map, and analyze existing data on Zia Pueblo's renewable energy resource base and then match resource attributes with the most suitable renewable technologies for tribal energy consumption and needs. Also, key impacts on cultural and social values of Zia Pueblo will be addressed. Selected most favorable uses and technologies will be further investigated to determine initial feasibility and market for business development for up to six sites located on tribal land. The anticipated result will be the recommended development of sites that have sufficient background study completed to warrant a business plan, detailed engineering feasibility, and acquisition of project financing. Valuable technical and economic information will accrue from this study that may be applied to scale up or down the various power technology potential on Zia Pueblo for maximum benefit and best area(s) of application, project phasing and potential for future replicability and expansion.

NREL Confirms Large Potential for Grid Integration of Wind, Solar Power (Fact Sheet)  

SciTech Connect (OSTI)

To fully harvest the nation's bountiful wind and solar resources, it is critical to know how much electrical power from these renewable resources could be integrated reliably into the grid. To inform the discussion about the potential of such variable sources, the National Renewable Energy Laboratory (NREL) launched two key regional studies, examining the east and west sections of the U.S. power grid. The studies show that it is technically possible for U.S. power systems to integrate 20%-35% renewable electricity if infrastructure and operational improvements can be made.

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 electricity—such as nuclear power plants—can 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.

A complete record of Holocene glacier variability at Austre Okstindbreen, northern Norway: an integrated approach  

Science Journals Connector (OSTI)

Arctic glaciers are currently undergoing major changes, but accurate knowledge about how they varied during the entire Holocene is still scarce. Here we present a new complete glacier record from Austre Okstindbreen in Nordland, northern Norway. This reconstruction is based on a number of short and long cores retrieved from several downstream basins, which have been analyzed by a suite of methods including geochemical elements (XRF), rock magnetic properties, dry bulk density (DBD) and Loss-on-ignition (LOI). Lake sediment distribution was surveyed and mapped prior to coring by the use of ground penetrating radar (GPR). Independently lichen-dated marginal moraines and historical information about the glacier frontal positions from old photographs and maps have made it possible to link the moraine sequence to the 210Pb dated lake sediment chronology. This integrated approach reveals that Austre Okstindbreen is the first known glacier in Scandinavia to possibly have survived the “Holocene Thermal Optimum”. It also brackets the four largest glacier advances to c 7400–7000, 1400–1200, 900–700 and 300–150 years before AD 2000 (b2k). In contrast to most reconstructed glaciers in Scandinavia, the largest glacier advance was not associated with the “Little Ice Age”, but rather to an earlier period centred at 1300 b2k. Both the moraine chronology and the lacustrine records document this Neoglacial advance. Compared to other glacier reconstructions from the Northern Hemisphere, we identify near-synchronous glacier advances occurring roughly at 4000 b2k; 2700 b2k; 1300 b2k and during the “Little Ice Age”. These correlative advances across the Northern Hemisphere suggest that these observed centennial-scale events are a shared feature regardless of the large geographical distances separating them. Some minor discrepancies between different geographical areas may be caused by lack of precise dating, but local climatic conditions may play a role as well.

Renewable Electricity Futures for the United States  

SciTech Connect (OSTI)

This paper highlights the key results from the Renewable Electricity (RE) Futures Study. It is a detailed consideration of renewable electricity in the United States. The paper focuses on technical issues related to the operability of the U. S. electricity grid and provides initial answers to important questions about the integration of high penetrations of renewable electricity technologies from a national perspective. The results indicate that the future U. S. electricity system that is largely powered by renewable sources is possible and the further work is warranted to investigate this clean generation pathway. The central conclusion of the analysis is that renewable electricity generation from technologies that are commercially available today, in combination with a more flexible electric system, is more than adequate to supply 80% of the total U. S. electricity generation in 2050 while meeting electricity demand on an hourly basis in every region of the United States.

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

Science Journals Connector (OSTI)

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

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

Renewable energy in Armenia  

Science Journals Connector (OSTI)

Armenia does not have any fossil fuel or coal reserves; therefore, it is entirely dependent on the imported fuel for transportation, electricity generation, and heat production. Armenian Government has plans to develop renewable energy resources. Renewable energy may not be the major source of energy development in Armenia but it should be an important component of it. A renewable energy road map for Armenia was prepared to evaluate feasible and reasonable renewable energy resources and plan a course of action for utilising them. This paper is a summary of the findings and conclusions of the studies and the roadmap.

Integrating Wind and Solar Energy in the U.S. Bulk Power System: Lessons from Regional Integration Studies  

SciTech Connect (OSTI)

Two recent studies sponsored by the U.S. Department of Energy (DOE) and the National Renewable Energy Laboratory (NREL) have examined the impacts of integrating high penetrations of wind and solar energy on the Eastern and Western electric grids. The Eastern Wind Integration and Transmission Study (EWITS), initiated in 2007, examined the impact on power system operations of reaching 20% to 30% wind energy penetration in the Eastern Interconnection. The Western Wind and Solar Integration Study (WWSIS) examined the operational implications of adding up to 35% wind and solar energy penetration to the Western Interconnect. Both studies examined the costs of integrating variable renewable energy generation into the grid and transmission and operational changes that might be necessary to address higher penetrations of wind or solar generation. This paper identifies key insights from these regional studies for integrating high penetrations of renewables in the U.S. electric grid. The studies share a number of key findings, although in some instances the results vary due to differences in grid operations and markets, the geographic location of the renewables, and the need for transmission.

Electricity consumption from renewable and non-renewable sources and economic growth: Evidence from Latin American countries  

Science Journals Connector (OSTI)

Abstract This study explores the effect of renewable and non-renewable electricity consumption on economic growth in 18 Latin American countries. To achieve the goal of this study a panel Gross Domestic Product (GDP) model was constructed taking the period 1980–2010 into account. From the Pedroni cointegration test results it was found that renewable electricity consumption, non-renewable electricity consumption, labor, gross fixed capital formation, and total trade are cointegrated. Moreover, the panel Dynamic Ordinary Least Squares (DOLS) test results revealed that all above the mentioned variables have a long run positive effect on GDP growth in the investigated countries. The Vector Error-Correction (VEC) Granger causality model results revealed the existence of feedback causality between the variables. The results of the study indicated that renewable electricity consumption is more significant than non-renewable electricity consumption in promoting economic growth in the investigated countries in the long run and the short run. Based on the results of this study, it is recommended that the investigated countries should increase their investment on renewable energy projects to increase the role of electricity consumption from renewable sources. In addition, it is essential that these countries should reduce their non-renewable electricity consumption by increasing their energy efficiency and implementing energy saving projects. By applying these recommendations, these countries would be able to mitigate global warming and reduce their dependency on fossil fuel to increase their energy security.

Grid-Interactive Renewable Water Heating Economic and Environmental Value  

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

1 1 Grid-Interactive Renewable Water Heating Economic and Environmental Value Grid-interactive renewable water heaters have smart controls that quickly change their charge rate and charge level, factoring in renewable generation and other critical needs of the grid; thereby significantly reducing carbon emissions and bringing a new dimension of conservation and efficiency to the electric grid. The Steffes grid-interactive renewable water heater controller provides utilities with an affordable and effective way to integrate renewable generation into the grid while providing uninterrupted hot water to the consumer. In recent years, many states have set Renewable Portfolio Standards (RPS) to reduce the need for traditional fossil fuel-based power generation, thereby improving our environment and decreasing

Western Wind and Solar Integration Study  

SciTech Connect (OSTI)

The Western Wind and Solar Integration Study (WWSIS) is one of the largest regional wind and solar integration studies to date. It was initiated in 2007 to examine the operational impact of up to 35% energy penetration of wind, photovoltaics (PV), and concentrating solar power (CSP) on the power system operated by the WestConnect group of utilities in Arizona, Colorado, Nevada, New Mexico, and Wyoming (see study area map). WestConnect also includes utilities in California, but these were not included because California had already completed a renewable energy integration study for the state. This study was set up to answer questions that utilities, public utilities commissions, developers, and regional planning organizations had about renewable energy use in the west: (1) Does geographic diversity of renewable energy resource help mitigate variability; (2) How do local resources compare to out-of-state resources; (3) Can balancing area cooperation help mitigate variability; (4) What is the role and value of energy storage; (5) Should reserve requirements be modified; (6) What is the benefit of forecasting; and (7) How can hydropower help with integration of renewables? The Western Wind and Solar Integration Study is sponsored by the U.S. Department of Energy (DOE) and run by NREL with WestConnect as a partner organization. The study follows DOE's 20% Wind Energy by 2030 report, which did not find any technical barriers to reaching 20% wind energy in the continental United States by 2030. This study and its partner study, the Eastern Wind Integration and Transmission Study, performed a more in-depth operating impact analysis to see if 20% wind energy was feasible from an operational level. In DOE/NREL's analysis, the 20% wind energy target required 25% wind energy in the western interconnection; therefore, this study considered 20% and 30% wind energy to bracket the DOE analysis. Additionally, since solar is rapidly growing in the west, 5% solar was also considered in this study. The goal of the Western Wind and Solar Integration Study is to understand the costs and operating impacts due to the variability and uncertainty of wind, PV, and CSP on the grid. This is mainly an operations study, (rather than a transmission study), although different scenarios model different transmission build-outs to deliver power. Using a detailed power system production simulation model, the study identifies operational impacts and challenges of wind energy penetration up to 30% of annual electricity consumption.

Renewable Energy for Sustainable Rural Village Power  

SciTech Connect (OSTI)

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

Assumptions to the Annual Energy Outlook - Renewable Fuels Module  

Gasoline and Diesel Fuel Update (EIA)

Renewable Fuels Module Renewable Fuels Module Assumption to the Annual Energy Outlook Renewable Fuels Module The NEMS Renewable Fuels Module (RFM) provides natural resources supply and technology input information for forecasts of new central-station U.S. electricity generating capacity using renewable energy resources. The RFM has five submodules representing various renewable energy sources, biomass, geothermal, landfill gas, solar, and wind; a sixth renewable, conventional hydroelectric power, is represented in the Electricity Market Module (EMM).109 Some renewables, such as landfill gas (LFG) from municipal solid waste (MSW) and other biomass materials, are fuels in the conventional sense of the word, while others, such as wind and solar radiation, are energy sources that do not involve the production or consumption of a fuel. Renewable technologies cover the gamut of commercial market penetration, from hydroelectric power, which was an original source of electricity generation, to newer power systems using biomass, geothermal, LFG, solar, and wind energy. In some cases, they require technological innovation to become cost effective or have inherent characteristics, such as intermittency, which make their penetration into the electricity grid dependent upon new methods for integration within utility system plans or upon low-cost energy storage.

Hydrogen from renewable resources research  

SciTech Connect (OSTI)

In 1986 the Hawaii Natural Energy Institute (HNEI) and the Florida Solar Energy Center (FSEC) were contracted by the Solar Energy Research Institute (SERI) to conduct an assessment of hydrogen production technologies and economic feasibilities of the production and use of hydrogen from renewable resources. In the 1989/90 period all monies were directed toward research and development with an emphasis on integration of tasks, focusing on two important issues, production and storage. The current year's efforts consisted of four tasks, one task containing three subtasks: Hydrogen Production by Gasification of Glucose and Wet Biomass in Supercritical Water; Photoelectrochemical Production of Hydrogen; Photoemission and Photoluminescence Studies of Catalyzed Photoelectrode Surfaces for Hydrogen Production; Solar Energy Chemical Conversion by Means of Photoelectrochemical (PEC) Methods Using Coated Silicon Electrodes; Assessment of Impedance Spectroscopy Methods for Evaluation of Semiconductor-Electrolyte Interfaces; Solar Energy Conversion with Cyanobacteria; Nonclassical Polyhydride Metal Complexes as Hydrogen Storage Materials. 61 refs., 22 figs., 11 tabs.

Estimating the Value of Utility-Scale Solar Technologies in California Under a 40% Renewable Portfolio Standard (Report Summary) (Presentation)  

SciTech Connect (OSTI)

Concentrating solar power with thermal energy storage (CSP-TES) is a unique source of solar energy in that its output can be shifted over time. The ability of CSP-TES to be a flexible source of generation may be particularly valuable in regions with high overall penetration of solar energy, such as the state of California. California's Renewable Portfolio Standard (RPS) requires the state to increase generation from eligible renewable energy resources to reach 33% of retail electricity sales by 2020. Beyond 2020, California targets a further reduction in greenhouse gas emissions. To help reach this goal, current California governor Jerry Brown has stated that a higher 40% RPS might be reachable in the near term. The levelized cost of energy is generally emphasized when assessing the economic viability of renewable energy systems implemented to achieve the RPS. However, the operational and capacity benefits of such systems are often ignored, which can lead to incorrect economic comparisons between CSP-TES and variable renewable generation technologies such as solar photovoltaics (PV). Here we evaluate a 40% RPS scenario in a California grid model with PV or CSP-TES providing the last 1% of RPS energy. We compare the technical and economic implications of integrating either solar technology under several sensitivities, finding that the ability to displace new conventional thermal generation capacity may be the largest source of value of CSP-TES compared to PV at high solar penetrations.

Renewable energy and low carbon economy transition in India  

Science Journals Connector (OSTI)

Cooperation of large developing countries such as India would be important in achieving a low carbon future which can help in restricting the global temperature rise to 2 ? ° C . Global modeling studies of such low carbon scenarios point to a prominent role for renewable energy. This paper reports scenarios for a low carbon future in India. An integrated modeling framework is used for assessing the alternate development pathways having equal cumulative CO 2 emissions. The modeling period ranges from 2005 to 2050. The first pathway assumes a conventional development pattern together with a carbon price that aligns India’s emissions to an optimal 450 ppmv CO 2 -eq. stabilization global response. The second emissions pathway assumes an underlying sustainable development pattern. A low carbon future will be good for renewable energy under both the development pathways though the share of renewable energy will be higher under a sustainable pathway. Renewable energy faces competition from low carbon technologies like nuclear and carbon capture and storage in the electricity sector. Solar wind biomass and biofuels emerge as the four competitive renewable energy choices for India. Renewable development however depends critically on the reduction in the costs and in the ability to integrate the intermittent renewables within the existing systems for which technology transfer and capacity building hold the key.

success of any solar energy success of any solar energy installation depends largely on the site's solar resource. Therefore, detailed knowledge of an area's solar resource is critical to installation planning and siting. To help with these efforts, the National Renewable Energy Laboratory (NREL) and the National Climatic Data Center (NCDC) have updated the National Solar Radiation Database (NSRDB). Since 1992, the database has provided solar planners and designers, building architects and engineers, renewable energy analysts, and countless others with extensive solar radiation information. The 1991-2005 NSRDB contains hourly solar radiation (including global, direct, and diffuse) and meteorological data for 1,454 stations. This update builds on the 1961-1990 NSRDB, which contains

Renewal-anomalous-heterogeneous files  

E-Print Network [OSTI]

Renewal-anomalous-heterogeneous files are solved. A simple file is made of Brownian hard spheres that diffuse stochastically in an effective 1D channel. Generally, Brownian files are heterogeneous: the spheres' diffusion coefficients are distributed and the initial spheres' density is non-uniform. In renewal-anomalous files, the distribution of waiting times for individual jumps is exponential as in Brownian files, yet obeys: {\\psi}_{\\alpha} (t)~t^(-1-{\\alpha}), 0renewal as all the particles attempt to jump at the same time. It is shown that the mean square displacement (MSD) in a renewal-anomalous-heterogeneous file, , obeys, ~[_{nrml}]^{\\alpha}, where _{nrml} is the MSD in the corresponding Brownian file. This scaling is an outcome of an exact relation (derived here) connecting probability density functions of Brownian files and renewal-anomalous files. It is also shown that non-renewal-anomalous files are slower than the corresponding renewal ones.

Renewable power needs smart storage solutions  

SciTech Connect (OSTI)

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

Design of isolated renewable hybrid power systems  

SciTech Connect (OSTI)

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

Simulation study on lignite-fired power system integrated with flue gas drying and waste heat recovery – Performances under variable power loads coupled with off-design parameters  

Science Journals Connector (OSTI)

Abstract Lignite is a kind of low rank coal with high moisture content and low net heating value, which is mainly used for electric power generation. However, the thermal efficiency of power plants firing lignite directly is very low. Pre-drying is a proactive option, dehydrating raw lignite to raise its heating value, to improve the power plant thermal efficiency. A pre-dried lignite-fired power system integrated with boiler flue gas drying and waste heat recovery was proposed in this paper. The plant thermal efficiency could be improved by 1.51% at benchmark condition due to pre-drying and waste heat recovery. The main system performances under variable power loads were simulated and analyzed. Simulation results show that the improvement of plant thermal efficiency reduced to 1.36% at 50% full load. Moreover, the influences of drying system off-design parameters were simulated coupled with power loads. The variation tendencies of main system parameters were obtained. The influence of pre-drying degree (including moisture content of pre-dried lignite and raw lignite) on the plant thermal efficiency diminishes gradually with the decreasing power load. The dryer thermal efficiency and dryer exhaust temperature are also main factors and the influences on system parameters have been quantitatively analyzed.

Western Wind and Solar Integration Study Phase 2 (Presentation)  

SciTech Connect (OSTI)

This presentation accompanies Phase 2 of the Western Wind and Solar Integration Study, a follow-on to Phase 1, which examined the operational impacts of high penetrations of variable renewable generation on the electric power system in the West and was one of the largest variable generation studies to date. High penetrations of variable generation can induce cycling of fossil-fueled generators. Cycling leads to wear-and-tear costs and changes in emissions. Phase 2 calculated these costs and emissions, and simulated grid operations for a year to investigate the detailed impact of variable generation on the fossil-fueled fleet. The presentation highlights the scope of the study and results.

Renewable Energy Positioning System: Energy Positioning: Control and Economics  

SciTech Connect (OSTI)

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

Renewable Energy Sources Optimization: A Micro-Grid Model Design  

Science Journals Connector (OSTI)

Abstract This paper analyzes the possibility to develop the simple micro-grid model in optimizing the utilization of local renewable energy for on-grid area. The proposed micro-grid model integrates the power plants driven by renewable energy sources employing micro hydro (MHP) and photovoltaic system (PV) which is connected to grid system. This model is analyzed using HOMER and MATLAB software. Based on the load profiles and the availability of water resources, the HOMER simulates the proposed micro-grid model with three options of MHP capacity. The simulation results show that the micro-grid model with the largest capacity MHP produced the lowest energy cost, greatest reduction of CO2 emission, and largest fraction of renewable energy. However, these result required the expensive initial capital cost. In addition, the PV power generation was always recommended with a minimum capacity. Hence, MATLAB results show the performances of the power plants with renewable energy sources were used maximally.

New Mexico renewable development study  

SciTech Connect (OSTI)

Since the early 1990s, Los Alamos National Laboratory (LANL) has applied electric grid models and simulation software to problems of national significance. This effort continues with a variety of other projects funded by the Department of Energy (DOE), other federal and state agencies and private companies. Critical to the success of these programs is the ability to integrate regional-scale models of the electric grid, to assess the propagation of grid impacts, and to present interactively the effect of potential mitigating actions required to stabilize the grid. All of these capabilities are applied in this study, to accomplish the following goals and objectives: (1) Develop an AC power flow model representing future conditions within New Mexico's electric grid, using commercial tools accepted by the utility industry; (2) Conduct a 'screening' analysis of options for accelerating potential renewable energy development through the addition of a statewide transmission collector system; (3) Estimate total revenue needed, jobs created (temporary and permanent) plus indirect and direct impacts to the state's economy; (4) Evaluate potential cost allocation methodology; and (5) Issue a project report that will provide information for policy direction by state regulators, project developers, and legislators.

Renewable Natural Gas

Natural Gas Natural Gas JOHN DAVIS: The use of clean, domestic natural gas as highway fuel in place of imported oil is growing in popularity with fleets and trucking companies. While natural gas from underground deposits is arguably a limited resource, there is a renewable, eco-friendly resource that we have right here in the U.S.A. And we're here now to give you the straight poop! Every family, farm animal and food processing plant in America produces organic waste that creates a mix of methane, CO2 and other elements called bio gas when it decomposes. Rotten vegetables, moldy bread, last night's leftovers --- they all break down when our garbage gets to the land fill. Incredibly, for

Renewable Energy Certificate Program  

SciTech Connect (OSTI)

This project was primarily to develop and implement a curriculum which will train undergraduate and graduate students at the University seeking a degree as well as training for enrollees in a special certification program to prepare individuals to be employed in a broad range of occupations in the field of renewable energy and energy conservation. Curriculum development was by teams of Saint Francis University Faculty in the Business Administration and Science Departments and industry experts. Students seeking undergraduate and graduate degrees are able to enroll in courses offered within these departments which will combine theory and hands-on training in the various elements of wind power development. For example, the business department curriculum areas include economic modeling, finance, contracting, etc. The science areas include meteorology, energy conversion and projection, species identification, habitat protection, field data collection and analysis, etc.

Because original equipment Because original equipment manufacturer (OEM) vehicles designed to run on compressed natural gas (CNG) and liquefied petroleum gas (LPG) have only been available in limited models in past years, many fleets have had to rely on conversions as a source for alternative fuel vehicles (AFVs). The Federal fleet is no different-so far it has converted approximately 900 vehicles to CNG or LPG, providing the National Renewable Energy Laboratory (NREL) with an opportunity to test a variety of conversion kits. When buying a new AFV or having a gasoline vehicle convert- ed, fleet managers need to ask the right questions about the emis- sions performance they can expect, according to researchers at NREL. "Question them. Don't take [good emissions performance] for granted," said Robert Motta,

Renewable Energy Renewable Energy Accelerating the transition to alternative energy sources requires significant improvement in materials, chemicals, processes, and devices. To produce more cost-effective energy sources for the nation, Argonne is focused on renewable energy research. World energy demand is expected to double by 2050, and oil, coal and natural gas will have to supply much of that energy unless we can make renewable and "green" alternatives cheap enough to replace them. Argonne is using its expertise and creativity to explore the development, use and consequences of non-fossil energies. Our renewable energy research helps create groundbreaking technologies that will quickly put new options within our nation's reach.

Federal Energy Management Program: Purchasing Renewable Power  

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

Purchasing Renewable Power Purchasing Renewable Power Federal agencies can purchase renewable power or renewable energy certificates (RECs) from a utility or other organization to meet Federal renewable energy requirements. Renewable power and RECs are good choices for facilities where on-site projects may be difficult or capital budgets are limited. There are three methods for purchasing renewable power that's not generated on a Federal site: Renewable Energy Certificates: Also known as renewable energy credits, green certificates, green tags, or tradable renewable certificates, RECs represent the environmental attributes of the power produced from renewable energy projects and are sold separately from commodity electricity. RECs are an attractive option for Federal facilities located where renewable power is not readily available.
