Preface Electric Energy Systems Analysis and Operation :
The purpose of this book is to merge, update, and extend the material in both classical power system analysis books and power economics books, within the framework of currently restructured electric energy systems. This effort is clearly needed to address the operations and planning problems in nowadays unbundled generation, transmission, and distribution systems.
In addressing the aforementioned issues, we realized that the challenges were significant. First of all, we had to provide added value to the reference books on the topic. Fortunately, achieving this goal was facilitated by the economic and technical revolution that the electric sector has been undergoing during the last two decades. This revolution has dramatically changed or made obsolete many important concepts as they are considered in existing books.
Another difference between this and earlier books lies in the addition of some advanced chapters, which are usually covered in specialized monographs, as well as in the deeper treatment of certain classical topics. The second and perhaps more difficult challenge was the need to avoid an encyclopedic approach, both in scope and content. A book coauthored by 24 researchers, each one writing on his own area of expertise, can easily degenerate into a voluminous collection of disconnected papers, which might only be useful for a minority of specialists. Being aware of this risk, the authors have made a significant effort to begin with the basic principles, paying attention to the topics any power engineer should know, including many solved examples, and directing the reader to other chapters if necessary.
Some redundant material has been intentionally left out in order not to distract the reader’s attention by cross referencing. An added advantage of the approach used here is that many chapters become self-sufficient for those readers with a certainb background in power systems who simply desire to keep themselves updated. Our objective was to keep the spectrum of readers to whom this book is directed fairly broad. On the one hand, instructors and undergraduate students of engineering schools can use it as a textbook, with the material being possibly fully covered in two terms. Depending on the particular context, the instructor may have to pick up only a subset of chapters, discarding those that are covered in other subjects of the curriculum. This may be the case of protections, over voltages, synchronous machines, etc.
On the other hand, considering the advanced level of certain chapters, and the inclusion, for the first time in a textbook of this breadth and depth, of the regulatory issues, which are changing the electric sector, this volume can also serve as a handbook for graduate students and practicing professionals who lack the time to search for original sources (papers and technical reports). These readers will surely welcome the large number of references at the end of each chapter, which will allow them to acquire a deeper knowledge on the topics of their own interest.
It is assumed here that the reader has a minimum background in algebra (matrices, complex numbers, etc.), calculus (linear differential equations, Laplace and Fourier transform, etc.), physics (electromagnetic fields, rotating mass dynamics, etc.), circuits (nodal equations, three-phase circuits, etc.) and, if possible, electric machines and microeconomics.
This is usually the case of those undergraduate students who enroll for the first time in a course on power system analysis. Owing to space limitations, the book is mainly focused on the operation of generation and transmission systems, although part of the material (e.g., certain component models, three-phase and harmonic load flows, reliability indices and protections) is of application also in the analysis of distribution networks. For the same reason, the long-term planning problem has not been explicitly dealt with; nevertheless, several chapters and parts of others (e.g., load flow, generation scheduling, security, reliability, and stability) present essential tools for network expansion studies, design and comparison of alternatives, etc., which are directly linked with the short-term planning problem.
