Download or read book WIND POWER CAPACITY VALUE METRICS AND VARIABILITY written by Frederick W. Letson and published by . This book was released on 2015 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Capacity value is the contribution of a power plant to the ability of the power system to meet high demand. As wind power penetration in New England, and worldwide, increases so does the importance of identifying the capacity contribution made by wind power plants. It is critical to accurately characterize the capacity value of these wind power plants and the variability of the capacity value over the long term. This is important in order to avoid the cost of keeping extra power plants operational while still being able to cover the demand for power reliably. This capacity value calculation is particularly interesting because wind power output and demand for electricity are not statistically independent. They are both driven by the weather. This dissertation describes a model of the New England power system in the presence of increasing wind power penetration, used to achieve three major ends: 1. To evaluate the magnitude of the contribution that wind power would make to resource adequacy in the New England Power system at various levels of penetration (up to 50%). 2. To characterize the inter-annual variability in that contribution. 3. To assess various capacity value metrics with regard to their ability to predict the long term capacity value of wind power plants, especially based on limited data. 4. To characterize the interaction of wind power plants and energy storage with respect to capacity value. These ends were achieved by completing three studies: a long-term study based on measured wind data, a high-penetration study based on synthesized data, and an investigation of the effect of grid-scale energy storage. While the methods used in these studies are generally applicable, New England is used as a consistent example since many of these phenomena are strongly affected by the regional wind and power system characteristics. The results of this work show that wind power capacity value is relatively high at low penetration and decreases substantially as penetration increases to 50% and that this is not significantly improved by the inclusion of grid-scale (daily load-shifting) energy storage. Also, the capacity value of this energy storage, considered separately is relatively high, and not strongly dependent on wind energy penetration level. In future power systems with higher wind penetrations than 50% or those relying on longer-term storage (which could be necessary to reach very high levels of renewable penetration), new metrics of capacity value may be necessary to ensure system adequacy

Book excerpt: Electric utility planners and wind energy researchers pose a common question: What is the capacity value of a wind plant? Tentative answers, which can be phrased in a variety of ways, are based on widely varying definitions and methods of calculation. From the utility's point of view, a resource that has no capacity value also has a reduced economic value. Utility planners must be able to quantify the capacity value of a wind plant so that investment in conventional generating capacity can be potentially offset by the capacity value of the wind plant. Utility operations personnel must schedule its conventional resources to ensure adequate generation to meet load. Given a choice between two resources, one that can be counted on and the other that can't, the utility will avoid the risky resource. This choice will be reflected in the price that the utility will pay for the capacity: higher capacity credits result in higher payments. This issue is therefore also important to the other side of the power purchase transaction -- the wind plant developer. Both the utility and the developer must accurately assess the capacity value of wind. This article summarizes and evaluates some common methods of evaluating capacity credit. During the new era of utility deregulation in the United States, it is clear that many changes will occur in both utility planning and operations. However, it is my judgement that the evaluation of capacity credit for wind plants will continue to play an important part in renewable energy development in the future.

This book was released on 2013-03-15 with total page 138 pages. Available in PDF, EPUB and Kindle. Book excerpt: The world is witnessing a rapid growth in wind and other renewable based electricity generation due to environmental concerns associated with electricity generation from the conventional sources. Wind power behaves quite differently than conventional electric power generating units due to its intermittent and diffuse nature. System planners and operators face the variability and uncertainty of wind power availability, and therefore, encounter considerable challenges in making decisions to maintain the adequacy and security of wind integrated power systems. This volume intends to bring out the original research work of researchers from academia and industry in understanding, quantifying and managing the risks associated with the uncertainty in wind variability in order to plan and operate a modern power system integrated with a significant proportion of wind power generation with an acceptable level of reliability. Accurate modeling of wind power variability and proper incorporation of the models in reliability and risk evaluation is very important for the planning and operation of electric power systems, and will play a crucial role in defining the requirement of various types of resources and services, such as storage and ancillary services in power systems.
Download or read book Valuing Wind Generation on Integrated Power Systems written by Ken Dragoon and published by William Andrew. This book was released on 2010-09-28 with total page 242 pages. Available in PDF, EPUB and Kindle. Book excerpt: Wind powered generation is the fastest growing energy source in the United States due to a combination of economic incentives, public preference for renewable energy as expressed in government policies, competitive costs, and the need to address global warming. The economic consequences of the relative variability and lower predictability of wind generation are not easily captured in standard economic analyses performed by utility planners. This book provides utility analysts and regulators a guide to analyzing the value of wind generation in the context of modern power systems.Guiding the reader through the steps to understanding and valuing wind generation on modern power systems, this book approaches the issue from the various, current perspectives in the US. These include utilities that are still primarily vertically integrated power providers and systems dominated by independent system operators (ISOs). Outlined here are the basic procedures in a wind valuation study, described with enough detail so that analysts spanning a range of resources and sophistication can reasonably undertake a competent study. Descriptions of studies performed by other utilities are also provided, explaining their specific approaches to the fundamentals. Finally, it includes a short section on power systems that utilize relatively large fractions of wind, and how operating procedures and valuing techniques may need alteration to accommodate them.• Reviews operating challenges that large amounts of wind power present to power systems operators • Outlines alternative approaches to quantifying the systems services necessary to accommodate the wind • Explains how economic analyses of wind generation are competently performed • Describes how to represent wind generation in computer models commonly used by electric utility planners that may not be specifically designed to incorporate wind generation • Reviews methods used by some select utility companies around the United States • Touches on key European issues involving relatively high levels of wind generation • Written at the level of the utility planner, assuming a basic understanding of economic dispatch of generators and elementary statistics Outlines the role of wind forecasting in wind valuation studies Evaluates the importance of estimating wind generation to meet peak demand Researches how the market structure effects the value of wind energy Discusses power systems that utilize relatively large fractions of wind power Highlights the operating procedures that can enhance the value of wind generation

Available in PDF, EPUB and Kindle. Book excerpt: Examines the possible societal impacts of wind energy projects and explains the potential issues faced when siting, constructing, and operating a wind energy project. This book begins with a history of wind power and the social impacts of both electricity and wind power from a historical perspective, a discussion of basic electrical terms, and a primer on the conversion of power in the wind to electricity. Much of the second half of the book is devoted to comparing wind energy to other forms of electric generation, both renewable and non-renewable sources. In order to have a true understanding of the impact of wind energy on society, one also has to have a thorough understanding of the impacts that other sources of electric generation have, such as fossil-fuelled plants or nuclear power plants. The comparison of electric generation sources includes a review of how such sources are typically utilized within the electric system, as well as the economic factors and environmental considerations that affect which resources utilities or operators of electric grids have to take into account. The authors conclude with a discussion of energy policies in the U.S., individual states, and foreign nations, how these policies influence the use of renewable energy, and what our future may hold in terms of energy supply and demand. Some highlights of this book are: Discusses the wind energy impacts on the environment, local economy, electric utilities, individuals and communities Provides a visual explanation of wind energy principles through tables, graphs, maps, illustrations and photographs Offers a comprehensive overview of the issues associated with the creation and use of wind energy Models chapters around an existing university curriculum Spanning the broad range of environmental, financial, policy and other topics that define and determine the relationships between wind energy technology and our energy-dependent society, Wind Energy Essentials is a resource for students, universities, and the entire wind energy industry.
Download or read book Capacity Value of PV and Wind Generation in the NV Energy System written by and published by . This book was released on 2014 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Calculation of photovoltaic (PV) and wind power capacity values is important for estimating additional load that can be served by new PV or wind installations in the electrical power system. It also is the basis for assigning capacity credit payments in systems with markets. Because of variability in solar and wind resources, PV and wind generation contribute to power system resource adequacy differently from conventional generation. Many different approaches to calculating PV and wind generation capacity values have been used by utilities and transmission operators. Using the NV Energy system as a study case, this report applies peak-period capacity factor (PPCF) and effective load carrying capability (ELCC) methods to calculate capacity values for renewable energy sources. We show the connection between the PPCF and ELCC methods in the process of deriving a simplified approach that approximates the ELCC method. This simplified approach does not require generation fleet data and provides the theoretical basis for a quick check on capacity value results of PV and wind generation. The diminishing return of capacity benefit as renewable generation increases is conveniently explained using the simplified capacity value approach.
