As demonstrated by recent major blackouts, power grids and their associated markets play a vital role in the operation of our society. Understanding how electric generation, transmission, and delivery systems interact and operate is paramount to guaranteeing reliable sources of electricity.
Electric Energy Systems offers highly comprehensive and detailed coverage of power systems operations, uniquely integrating technical and economic analyses. The book fully develops classical subjects such as load flow, short-circuit analysis, and economic dispatch within the context of the new deregulated, competitive electricity markets.
With contributions from 24 internationally recognized specialists in power engineering, the text also presents a wide range of advanced topics including harmonic load flow, state estimation, and voltage and frequency control as well as electromagnetic transients, fault analysis, and angle stability.
A well-needed and updated extension on classical power systems analysis books, Electric Energy Systems provides an in-depth analysis of the most relevant issues affecting the blood-line of our society, the generation and transmission systems for electric energy.

Edition 1st Edition. First Published For the same reason, the long-term planning problem has not been explicitly dealt with; nevertheless, several chapters and parts of others e.
A possibility could have been to begin with the most classical chapters load flow, frequency regulation, economic dispatch, short circuits, and transient stability , and then continue with what could be labeled advanced topics market issues, state estimation, electromagnetic transients, harmonics, etc.
However, it is difficult in many cases to place the division between basic and advanced material properly speaking, particularly in those chapters specifically dealing with the operation of generation and transmission systems. The scheme adopted in this book is based instead on the different working regimes of the power system, which are crucial to determine the techniques and tools needed to study the time scales involved.
The five chapters following the introductory one cover what is essentially the balanced sinusoidal steady-state regime, which, rigorously speaking, should be called quasi-steady-state because of the slow but continuous variation of the loads. In this context, mainly related to the real-time operation of power systems, phasors and complex power constitute the basic tools on which the different analytical and computational methods are built.
On the other hand, the last six chapters are devoted to the transient and nonsinusoidal states of a power system, including both balanced and unbalanced conditions. The system under transients originated by faults is first dealt with, followed by the slower electromechanical oscillations, to end with the faster electromagnetic transients.
Chapter 1 makes an original presentation of what power systems have been in the past and what they have become nowadays, from the technical, economical and regulatory points of view.
It constitutes by itself very valuable material to be disseminated among those young students who erroneously believe that professional challenges can only be found in computer engineering and communications. Besides conventional components, Chapter 2 briefly deals with cables and asynchronous machine modeling, of renewed interest in view of the growth of distributed generation.
An introduction to load forecasting techniques is also presented. In Chapter 3, which is devoted to the classic power flow or load flow problem, the section on large-scale systems, complemented by Appendix A, stands out. The reader may find interesting the discussion about the simplifications behind the fast decoupled load flow.
Power flow and voltage regulating devices are presented, starting from a common framework, in an original manner.
Chapter 4 provides many more details than it is usual in textbooks about advanced topics related to state estimation, like nonquadratic estimators and topology error identification.
Chapter 5 starts with a rigorous and general treatment of the economic dispatch problem, paying special attention to transmission loss coefficients, and finishes with the formulation of the optimization problems currently faced by producers, consumers, and other agents of electricity markets.
The presence of Chapter 6, entirely devoted to the operation of the transmission subsystem, is new in textbooks of this nature, but we believe it is fundamental to provide a comprehensive view of all the problems and tasks involved at this level. The new paradigm under which transmission networks are operated, based on open and nondiscriminatory access, and the resulting challenges are presented and discussed in this chapter.
The second part of the book starts with Chapter 7, which is devoted to a general treatment of three-phase linear and nonlinear models of power system components, including power electronics components, such as filters, voltage-source converters, etc. Several of the models described here are used in the following chapters. Chapter 8 comprises two closely related subjects, namely fault analysis, including a brief reference to grounding systems, and protections. More attention than usual is paid to the matrix-based systematic analysis of short circuits in large-scale systems.
Automatic regulation and control of voltages and frequency is dealt with in Chapter 9 from a broader perspective, beginning with local or primary control strategies and ending with the regionwide secondary and tertiary control schemes. These controls and associated concepts, such as hierarchical and wide-area control, are presented and discussed within the context of practical grid requirements in Europe and North America, and in view of their role in competitive electricity markets, particularly in relation to ancillary services.
This chapter assumes that the reader is familiar with basic system element models and controls, particularly those associated with the synchronous machine, as discussed in Chapters 7 and 9 and Appendix C. Each stability subtopic, that is, angle, voltage, and frequency stability, is first defined and the main concepts and analysis techniques are then explained using basic and simple system models. This is followed by a discussion of practical applications, analysis tools and measures for stability improvement, closing with a brief description of a real instability event, which is a unique feature of this book with respect to other textbooks in the topic.
Chapters 11 addresses again the power flow problem but under nonsinusoidal and unbalanced conditions. This chapter presents advanced topics whose relevance is steadily increasing, given the growing portion and size of electronic converters connected to power systems. Ignored or superficially covered in most textbooks, in Chapter 12 analytical and computational techniques for the study of electromagnetic transients are explained in detail, as well as some related applications, like propagation and limitation of overvoltages.
The book closes with three appendices covering the solution of large-scale sparse systems of linear equations Appendix A , the fundamentals of optimization Appendix B , and the modeling of induction and synchronous machines Appendix C. The analytical and computational techniques covered in this book have been selected taking into account that the speed of response in the analysis of very large nonlinear systems is often crucial for the results to be of practical use.
In this sense, electric energy systems constitute a unique case, because of their size, complexity, and strict control requirements. We are thankful to all the colleagues, students, and institutions who have helped us in the complex endeavor of editing and partly writing this book. We hope that this book will be helpful for the new generations of power engineering students and professionals, which is the sole motivation for this project.

This reality is being faced worldwide as basic energy resources have become scarce and increasingly costly.
While coal remains an abundant resource, oil and natural gas supply face restrictions, concerns arising on declining volumes in the long term. This reliance on energy for economic growth has historically implied dependence on third parties for energy supply, with geopolitical connotations, as energy resources have not been generally in places where high consumption has developed. Energy has transformed itself into a new form of international political power, utilized by owners of energy resources mainly oil and natural gas.
Within that framework, electricity has become a favorite form of energy usage at the consumer end, with coal, oil, gas, uranium, and other basic resources used to generate electricity.
With its versatility and controllability, instant availability and consumer-end cleanliness, electricity has become an indispensable, multipurpose form of energy. But electricity usage is even broader in the commercial and industrial domains: in addition to providing power for lighting and air conditioning, it drives motors with a host of applications: lifts, cranes, mills, pumps, compressors, lathes, or other machine tools, and so on and so forth: it is nearly impossible to imagine an industrial activity that does not use electricity.
Thus, modern societies have become totally dependent on an abundant electricity supply. In fact, this may be the point of view that prompted the revolution that has rocked electric energy systems worldwide, as they have been engulfed in the wave of liberalization and deregulation that has changed so many other sectors of the economy.
And yet electricity is defined by a series of properties that distinguish it from other products, an argument often wielded in an attempt to prevent or at least limit the implementation of such changes in the electricity industry.
The chief characteristic of electricity as a product that differentiates it from all others is that it is not susceptible, in practice, to being stored or inventoried.
Electricity can, of course, be stored in batteries, but price, performance, and inconvenience make this impractical for handling the amounts of energy usually needed in the developed world. Therefore, electricity must be generated and transmitted as it is consumed, which means that electric systems are dynamic and highly complex, as well as immense.
