Fernando L. Alvarado Copyright by Marcel Dekker, Inc. Preface Power system state estimation is an area that matured in the past three decades. Today, state estimators can be found in almost every power system control center.

While there have been numerous papers written on many different aspects of state estimation, ranging from its mathematical formulation to the implementation and start-up issues at the control centers, relatively few books have been published on this subject. This book is the product of a long-term collaboration between the authors, starting from the summer of when they worked at the University of Seville on a joint project that was sponsored by the Ministry of Science and Education of the Spanish Government.

Since then, they have spent two summers working together on different projects related to state estimation and continued their collaboration.

They each taught regular and short courses on this topic and developed class notes, which make up most of the material presented in this book. The chapters of the book are written in such a way that it can be used as a textbook for a graduate-level course on the subject. However, it may also be used as a supplement in an undergraduate-level course in power system analysis. Professionals working in the Reid of power systems may also find the chapters of the book useful as self-contained references on specific issues of interest.

The book is organized into nine chapters and two appendices. The introductory chapter provides a broad overview of power system operation and the role of state estimators in the overall energy management system configurations.

The second chapter describes the modeling of electric networks during steady state operation and formulates one of the most commonly used state estimation methods in power systems, namely the weighted least squares WLS method. Application of the WLS method to power system state estimation presents several challenges ranging from numerical instabilities to the handling of measurements with special constraints. Chapter 3 presents various techniques for addressing these problems.

Network observability is analyzed in Chapter 4, where a brief review of networks and Copyright by Marcel Dekker, Inc. Chapter 5 is concerned with detecting and identifying incorrect measurements. In this chapter, it is assumed that the WLS method is used for state estimation and bad data processing takes place after the convergence of the WLS state estimator. In Chapter 6, the topic of robust estimation is introduced and some robust estimation methods which have already been investigated for power system applications are presented.

Chapter 7 is about different methods of estimating transmission line parameters and transformer taps.

These network parameters are typically assumed to be perfectly known, despite the fact that errors in them significantly affect the state estimates. The problem of topology error identification is the topic of Chapter 8. Topology errors cause state estimators to diverge or converge to incorrect solutions. The challenges in detecting and identifying such errors and methods of overcoming them are presented in this chapter.

Finally, Chapter 9 discusses the use of ampere measurements and various issues associated with their presence in the measurement set. The book also has two appendices, one on basic statistics and the other on sparse linear equations. All chapters, except for the first one, end with some practice problems. These may be useful if the book is adopted for teaching a course at either the graduate or undergraduate level.

The first five chapters are recommended to be read in the given order since each one builds on the previously covered material. However, the last four chapters can be covered in any arbitrary order. It has been a pleasure to work with our many graduate students who have contributed to the development and implementation of some of the ideas in this book.

Finally, we are also grateful for the constant encouragement and support that we have received from our spouses, Aysen and Cati, during the preparation of this book. Contents Foreword Fernando L.

Frams J. Jam, Optical Communication Systems. Ghatak A. A system may be classified as stationary or non stationary.

During the period of operation, when Operation and Control in Power Systems controls are implemented, the system is normally assumed to be stationary. The system equations may be formulated either in the continuous mode or in the discrete mode. While measurements and predicted values are available at discrete intervals, continuous representation is the most familiar mode. Transformation from continuous to discrete formulation is a straight forward process.

A power system invariably, is stochastic in nature since the load demand is the most uncertain aspect in the operation of it. In addition, measurement uncertainty, errors, non availability of readings, etc. In most of the power system studies only a deterministic model is assumed, but when the situation demands the probabilistic model is also used. A modern power system required identification of the model and optimization of the same with reference to a performance criterion with computer predictive, adaptive, non interacting, sampled-data control for efficient operation.

Various models that are needed in analysis and for control are discussed and presented through out the book. Chapter 2 deals with load flow studies. They are performed to determine voltages, active and reactive powers, etc. Load flow solution is essential for continuous evaluation of the performance of the power systems so that suitable control measures can be taken in case of necessity. In practice it will be required to carry out numerous load flows under a variety of conditions.

Economic system operation can be defined in a more general sense as making the best use of the resources available, subject to a variety of requirements over any desired period of time. Economic power system operation deals with the means and techniques for achieving minimum operating cost to supply a given predicted load demand. It may be pointed out that extensive research has been carried out in this field covering topics such as economy of fuel, maintenance and overhaul schedules of equipment, starting and shut-down of generating plants, scheduling of generation to different units, exchange of power between neighbouring utilities and a wide range of problems related to hydrogeneration, like water usage, policies for different types of hydro plants reservoir, pondage, run-off river and pumped storage and their integration with the system, both hydraulically and electrically.

Different combinations of thermal and hydrogenerating plants give rise to different cost structures. Also, for a given combination of plants, the operational requirement of scheduling generating plants to supply the predicted load demand and subsequent formulation of loading pattern to be imposed on individual units committed to service to minimize the cost of supplying a given load is another important aspect of the problem.

In general, the ordering or committing plant to operate on one hand and loading of plant in operation on the other are the two facets of the economic operation, both considered separately in Chapter 3 and 4.

The loading of plant in operation'is related to'Cost minimization over short periods of time. Introduction This problem is called instantaneous, static or optimal point minimization. Committing of plants to service, by comparison, relates to larger periods of time and gives rise to a variational form ofthe problem in which the minimization required is that ofthe time integral of operating costs over the period for which programmes of plant unit commitment are formulated.

There are several problems associated with hydrothermal combined operation such as: 1. Fuel ordering, i. Plant ordering or unit commitment, i. Hydrothermal scheduling, i.

The economic objective of a schedule can be assumed either by the profit from energy sales or by the cost of energy production.

If the loads are fixed, then both the criteria result in the same schedule. However, under more realistic circumstances, i. Minimization of production costs is taken generaHy as the criterion for economic operation.The ultimate objective of power system control is to maintain continuous supply of power with acceptable quality. This adds a new BUS. A power system invariably. Equation 2. It is seen from the elements of the Jacobian in this case that the symmetry that existed in the rectangular coordinates case is no longer present now.
