The writing of this book was largely motivated by the ongoing unprecedented world-wide restructuring of the power industry. This move away from the traditional monopolies and toward greater competition, in the form of increased numbers of independent power producers and an unbundling of the main services that were until now provided by the utilities, has been building up for over a decade. This change was driven by the large disparities in electricity tariffs across regions, by technological developments that make it possible for small producers to compete with large ones, and by a widely held belief that competition will be beneficial in a broad sense. All of this together with the political will to push through the necessary legislative reforms has created a climate conducive to restructuring in the electric power industry. Consequently, since the beginning of this decade dramatic changes have taken place in an ever-increasing list of nations, from the pioneering moves in the United Kingdom, Chile and Scandinavia, to today's highly fluid power industry throughout North and South America, as well as in the European Community. The drive to restructure and take advantage of the potential economic benefits has, in our view, forced the industry to take actions and make choices at a hurried pace, without the usual deliberation and thorough analysis of possible implications. We must admit that to speak of "the industry" at this juncture is perhaps disingenuous, even misleading.
An examination of key issues in electric utilities restructuring. It covers: electric utility markets in and out of the USA; the Open Access Same-time Information System; tagging transactions; trading energy; hedging tools for managing risks in various markets; pricing volatility, risk and forecasting; regional transmission organization; and more. The text contains acronyms, a contract specifications sample, examples, and nearly 500 bibliographic citations, tables, and drawings.
Deregulation is a fairly new paradigm in the electric power industry. And just as in the case of other industries where it has been introduced, the goal of deregulation is to enhance competition and bring consumers new choices and economic benefits. The process has, obviously, necessitated reformulation of established models of power system operation and control activities. Similarly, issues such as system reliability, control, security and power quality in this new environment have come in for scrutiny and debate. In this book, we attempt to present a comprehensive overview of the deregulation process that has developed till now, focussing on the operation aspects. As of now, restructured electricity markets have been established in various degrees and forms in many countries. This book comes at a time when the deregulation process is poised to undergo further rapid advancements. It is envisaged that the reader will benefit by way of an enhanced understanding of power system operations in the conventional vertically integrated environment vis-a-vis the deregulated environment. The book is aimed at a wide range of audience- electric utility personnel involved in scheduling, dispatch, grid operations and related activities, personnel involved in energy trading businesses and electricity markets, institutions involved in energy sector financing. Power engineers, energy economists, researchers in utilities and universities should find the treatment of mathematical models as well as emphasis on recent research work helpful.
Restructuring Electric Power System gives readers a thorough understanding of the technology involved in this very recent advance field. Electricity is a commodity with several features that distinguish it from other goods and services. It cannot be stored and its instant transmission requires a network of wires. A pre-requisite for ensuring orderly transportation of electricity under new regulatory environment is the creation of an independent entity that would channelize and control its flow in an optimum manner and without any discrimination, just as a traffic policeman or air traffic controller does in respect of traffic flowing to and from several directions. This causes several issues which are dealt by this book systematically. This book shall be useful as text/reference to field engineers, undergraduate, postgraduate students and the research scholars working in this field. MATLAB M-files and SIMULINK have been included in some of the numerical examples to assist the analysis. Thus, the book includes topics power flow analysis, Power trading, restructured market, market forces and transmission issues, ATC, congestion management, AGC and ancillary services.
This book is a collection of selected research papers presented at the International Conference on Innovations in Electrical and Electronics Engineering (ICIEEE 2019), which was organized by the Guru Nanak Institutions, Ibrahimpatnam, Hyderabad, Telangana, India, on July 26–27, 2019. The book highlights the latest developments in electrical and electronics engineering, especially in the areas of power systems, power electronics, control systems, electrical machinery, and renewable energy. The solutions discussed here will encourage and inspire researchers, industry professionals, and policymakers to put these methods into practice.
The development of electric power systems has been made up of incremental innovations from the end of the 19th century and throughout the 20th century. The creation of deregulated electricity markets has brought about an emerging paradigm in which the relationships between producers, power system operators and consumers have changed enormously compared to the monopolistic case. The scope of this book is to provide fundamental concepts of the physics and operation of transmission and distribution lines, which is the content of Part 1, followed by the models and tools for the description and simulation of large electrical grids for steady state and transient operation. These advanced tools allow the physics and technology of power systems to be described and the algorithms of Ybus and Zbus matrices to be built for various studies such as short-circuit studies and load flow or transient phenomena analysis. Part 3 deals with the new organization concepts in the frame of deregulated markets. In this part the restructuring of the power industry is presented where various actors interact together through market places or bilateral contracts. In addition, the operation of the power grids under this deregulated context is detailed and the relationships between power system operators and market actors (energy producers and providers, traders, etc.) is explained with several examples. The ancillary services, congestion management and grid access concepts are also described. A large number of exercises and problems disseminated throughout the book with solutions at the end enable the reader to check his understanding of the content at any time.
"At a time when bulk power systems operate close to their design limits, the restructuring of the electric power industry has created vulnerability to potential blackouts. Prompt and effective power system restoration is essential for the minimization of downtime and costs to the utility and its customers, which mount rapidly after a system blackout. Power System Restoration meets the complex challenges that arise from the dynamic capabilities of new technology in areas such as large-scale system analysis, communication and control, data management, artificial intelligence, and allied disciplines. It provides an up-to-date description of the restoration methodologies and implementation strategies practiced internationally. The book opens with a general overview of the restoration process and then covers: * Techniques used in restoration planning and training * Knowledge-based systems as operational aids in restoration * Issues associated with hydro and thermal power plants * High and extra-high voltage transmission systems * Restoration of distribution systems Power System Restoration is essential reading for all power system planners and operating engineers in the power industry. It is also a valuable reference for researchers, practicing power engineers, and engineering students." Sponsored by: IEEE Power Engineering Society
