Power System Economic and Market Operations

By Jin Zhong Copyright 2018

    Power system operation is one of the important issues in the power industry. The book aims to provide readers with the methods and algorithms to save the total cost in electricity generation and transmission. It begins with traditional power systems and builds into the fundamentals of power system operation, economic dispatch (ED), optimal power flow (OPF), and unit commitment (UC). The book covers electricity pricing mechanisms, such as nodal pricing and zonal pricing, based on Security-Constrained ED (SCED) or SCUC. The operation of energy market and ancillary service market are also explored.

    "It covers a wide range of interesting topics, which could be very useful for understanding the main phenomena ruling power systems economy (such as Optimal Power Flow analysis and unit Commitments). It addresses topics widely treated in the literature, hence it is important to outline its distinctive features compared to other similar books. The book is well structured and well balanced."

    "This book focuses on mathematical models in the software guiding the operation of electric power systems for both vertically integrated and market-based systems. It provides readers with full grasp of constraints imposed by the complexity of power system operation, as well as modeling limitation. Such understanding helps possible future improvements in engineering design and operating guidelines when technology further advances.
    Numerical examples in the book are very useful in illuminating the principles, as well as the way they are applied in practice.
    The comprehensive coverage and clear exposition of topics make this book an excellent textbook for students and a handy reference for practicing engineers."
