Power System Operation With Large Scale Stochastic Wind Power Integration

This book addresses the uncertainties of wind power modeled as interval numbers and assesses the physical modeling and methods for interval power flow, interval economic dispatch and interval robust economic dispatch. In particular, the optimization models are set up to address these topics and the state-of-the-art methods are employed to efficiently solve the proposed models. Several standard IEEE test systems as well as real-world large-scale Polish power systems have been tested to verify the effectiveness of the proposed models and methods. These methods can be further applied to other research fields that are involved with uncertainty.

The second edition of the highly acclaimed Wind Power in Power Systems has been thoroughly revised and expanded to reflect the latest challenges associated with increasing wind power penetration levels. Since its first release, practical experiences with high wind power penetration levels have significantly increased. This book presents an overview of the lessons learned in integrating wind power into power systems and provides an outlook of the relevant issues and solutions to allow even higher wind power penetration levels. This includes the development of standard wind turbine simulation models. This extensive update has 23 brand new chapters in cutting-edge areas including offshore wind farms and storage options, performance validation and certification for grid codes, and the provision of reactive power and voltage control from wind power plants.

Carefully edited for a highly coherent structure, this work remains an essential reference for power system engineers, transmission and distribution network operator and planner, wind turbine designers, wind project developers and wind energy consultants dealing with the integration of wind power into the distribution or transmission network. Up-to-date and comprehensive, it is also useful for graduate students, researchers, regulation authorities, and policy makers who work in the area of wind power and need to understand the relevant power system integration issues.

This book outlines the challenges that increasing amounts of renewable and distributed energy represent when integrated into established electricity grid infrastructures, offering a range of potential solutions that will support engineers, grid operators, system planners, utilities, and policymakers alike in their efforts to realize the vision of moving toward greener, more secure energy portfolios. Covering all major renewable sources, from wind and solar, to waste energy and hydropower, the authors highlight case studies of successful integration scenarios to demonstrate pathways toward overcoming the complexities created by variable and distributed generation.

The book attempts to provide a solid grounding in all significant aspects of wind power integration for engineers in a variety of disciplines. Thus a mechanical engineer will learn sufficient electrical power engineering to understand wind farm voltage regulation and fault ride-through problems; while an electrical engineer will benefit from the treatment of wind turbine aerodynamics. They will both wish to understand electricity markets, and in particular how wind energy is likely to fare. The introductory chapter charts the remarkable growth of wind energy since 1990. The various technical options for wind power extraction are outlined. This chapter then goes on to describe the potential problems of large-scale wind integration, and outlines some possible solutions. The second chapter is essentially an electrical power engineering primer, which will enable non-electrical engineers to cope with the concepts presented in Chapters 3 and 4. Chapter 3 deals with wind turbine generator technology, with particular attention being paid to current variable-speed designs. Chapter 4 is concerned with wind farm connection, and the implications for network design - an area lacking an established methodology to deal with variable generation. Chapter 5 addresses the key issue of power system operation in the presence of largely unpredictable wind power with limited scope for control. Energy storage provides a tempting solution; the treatment here concentrates on realistic, low-cost options and imaginative use of existing pumped storage plant. The importance of wind power forecasting is emphasised, and forms the main theme of Chapter 6. The encouraging progress in the last decade is described. Ensemble forecasting offers a useful operational tool, not least by providing the system operator with an indication of forecast reliability. Finally, Chapter 7 summarises the main types of electricity market, and discusses the prospects for wind power trading. The main renewable energy support schemes are explained and discussed.

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
