Statistical Synthesis of Physically Based Load Models with Applications to Cold Load Pickup
Physically based load models are useful in the planning, operation and control of power systems, especially when it is necessary to predict the behavior of the system load due to changes in the system. This paper presents a methodology for predicting the load at a point in the system starting from elementary component load models. The methodology consists of three key steps: modeling of elementaxy component loads; classification into homogeneous (similar) groups; and aggregation of the load models in each homogeneous group using statistical techniques. The methodology is illustrated with the cold load pickup problem, Where a mathematical model for the evolution of the fraction of ?>on?> space heaters is developed. The resulting model consists of a system of coupled ordinary and partial differential equations for each homogeneous group of component loads. Numerical solutions of the equations are used to predict the fraction of honh loads. The methodology is also applicable to direct load management.

Numerical Analysis in Electromagnetics
EM modeling and simulation (EMMODSIM) necessitates a good understanding and use of numerical analysis. Builtin MATLAB functions such as roots(), diff(), gradient(), trapz(), and inv() can be used for most of numerical analysis jobs. Although MATLAB makes life easy for engineers, EMMODSIM people should always depend on their own codes; at least aware of and well understand what is going on behind these builtin commands. This chapter reviews briefly some numerical analysis fundamentals which are essential for EMMODSIM studies. Taylor's expansion is one of a few important methods for the numerical solution of ordinary differential equations (ODEs). An important topic in numerical analysis is the root finding of a given nonlinear function. Method of moments (MoM) is used to solve linear systems of equations. Multiloop circuits are also solved using linear systems of equations.

Most neural network programs for personal computers simply control a set of fixed, canned networklayer algorithms with pulldown menus. This new tutorial offers handson neural network experiments with a different approach. A simple matrix language lets users create their own neural networks and combine networks, and this is the only currently available software permitting combined simulation of neural networks together with other dynamic systems such as robots or physiological models. The enclosed student version of DESIRE/NEUNET differs from the full system only in the size of its data area and includes a screen editor, compiler, color graphics, help screens, and readytorun examples. Users can also add their own help screens and interactive menus.The book provides an introduction to neural networks and simulation, a tutorial on the software, and many complete programs including several backpropagation schemes, creeping random search, competitive learning with and without adaptiveresonance function and "conscience," counterpropagation, nonlinear Grossbergtype neurons, Hopfieldtype and bidirectional associative memories, predictors, function learning, biological clocks, system identification, and more.In addition, the book introduces a simple, integrated environment for programming, displays, and report preparation. Even differential equations are entered in ordinary mathematical notation. Users need not learn C or LISP to program nonlinear neuron models. To permit truly interactive experiments, the extrafast compilation is unnoticeable, and simulations execute faster than PC FORTRAN.The nearly 90 illustrations include block diagrams, computer programs, and simulationoutput graphs.Granino A. Kom has been a Professor of Electrical Engineering at the University of Arizona and has worked in the aerospace industry for a decade. He is the author of ten other engineering texts and handbooks.

Mathematical Formulations for Electromagnetic Fields
There are various mathematical formulations for representing electromagnetic fields. They are equivalent to each other mathematically, but distinct in terms of numerical behavior. In this chapter, we will give a brief introduction to the three kinds of mathematical formulations employed in computational electromagnetics: vector partial differential equations, vector wave equations, and vector integral equations, which are the mathematical foundations of the finitedifference timedomain (FDTD) method, the finite element method (FEM), and the method of moment (MoM), respectively.

Electromagnetic Theory: Basic Review
This chapter brings together fundamental electromagnetic (EM) concepts, mathematical relations, and physical meanings. It illustrates three wellknown coordinate systems and discusses the relations among them. Electromagnetic problems such as antenna radiation or radar crosssection prediction are better modeled via vector (and scalar) potentials. The concept of delta function is used in EM source representations. Guided wave propagation problems in telecommunications media are best treated using reduced equations obtained from the longitudinal and transverse decomposition of Maxwell equations. This yields the wellknown transverse electric (TE), transverse magnetic (TM), and transverse EM (TEM) field representations under different polarizations. Electromagnetic problems involve linear, secondorder differential equations. Any linear, secondorder PDE can be classified as elliptic, hyperbolic, or parabolic.

Techniques for Solving AC Circuits
This chapter is mainly devoted to the analysis of alternating current (AC) circuits, in which all the quantities (mainly currents, voltages, powers) vary as sinusoids over time. In addition, it deals with two kinds of circuits in which the quantities do not vary as sinusoids, namely the RL circuit (containing a resistor and an inductor) and the RC circuit (containing a resistor and a capacitor). The chapter introduces circuit branches, whose idealized behaviour can be mathematically described by other constitutive equations. Since these are differential equations, it shows that the corresponding components have some energy storage capability and are therefore called globally energy storage elements. The phasors circuit was introduced, showing that Kirchhoff's equations can be written directly in terms of phasors.

Computation of the Exponential Matrix
Although state variable concepts are a part of modern control theory, they have not been extensively applied in communication theory. The purpose of this book is to demonstrate how the concepts and methods of state variables can be used advantageously in analyzing a variety of communication theory problems. In contrast to the impulse response and covariance function description of systems and random processes commonly used in the analysis of communication problems, Professor Baggeroer points out that a state variable approach describes these systems and processes in terms of differential equations and their excitation, which is usually a whitenoise process. Theoretically, such a description provides a very general characterization on which a large class of systems, possibly time varying and nonlinear, can be modeled. Practically, the state variable approach often provides a more representative physical description of the actual dynamics of the systems involved and, most importantly, can lead to solution techniques that are readily implemented on a computer and that yield specific numerical results.The work focuses on how state variables can be used to solve several of the integral equations that recur in communication theory including, for example, the KahunenLoeve theorem, the detection of a known signal in the presence of a colored noise, and the WienerHopf equation. The book is divided into two parts. The first part deals with the development from first principles of the state variable solution techniques for homogeneous and inhomogeneous Fredholm integral solutions. The second part considers two specific applications of the author's integral equation theory: to optimal signal design for colored noise channels, and to linear estimation theory.The main thrust o f the material presented in this book is toward finding effective numerical procedures for analyzing complex problems. Professor Baggeroer has combined several different mathematical tools not commonly used together to attack the detection and signal design problems. Numerous examples are presented throughout the book to emphasize the numerical aspects of the author's methods. If the reader is familiar with detection and estimation theory and with deterministic state variable concepts, the ideas, techniques, and results contained in this work will prove highly relevant, if not directly applicable, to a large number of communication theory problems.MIT Research Monograph No. 61
