## Description

During the past 20 years, Ali Keyhani’s research was supported by the National Science Foundation.∗ This book was conceived based on the work supported by these grants. The authors recognized the need for a book where the three areas of electrical engineering—power system engineering, control systems engineering, and power electronics—must be integrated to address the integration of a green and renewable energy system into electric power systems. The approach to integration of these three areas differs from classical methods. Due to complexity of this task, the authors decided to present the basic concepts and then present a simulation testbed inMATLAB to use these concepts to solve a basic problem in integration of green energy in electric power systems in the form of a project. Therefore, each chapter has three parts: First a problem of integration is stated and its importance is described. Then, the mathematical model of the same problem is formulated. Next, the solution steps are outlined. This step is followed by developing aMATLAB simulation testbed for the same problem. Finally, the results of the project are presented; where applicable, the experimental results are also presented. The book can be used as a textbook for instruction or by researchers. Since every chapter presents a project, an instructor can use these projects with some changes in parameters or control objectives as learning exercises for students. It is suggested that this book be used as an undergraduate and graduate course for students who had some background in power systems, power electronics, and control engineering. However, since the projects of this book are goal-oriented, instructors can use the book as an interdisciplinary graduate course for electrical and mechanical engineers if the book is supplemented by supporting concepts that students may need.

The book focus is on control of power converters, and we present how the inverters can be controlled to act as steam units and to provide active and reactive power. We will also present the fundamental architectures in design of smart grid distributed generation. In Chapter 1, the two fundamental architectures, namely DC architecture and AC architecture for integration of smart grid distributed generation, are presented. In Chapter 2, we present the inverter control voltage and current in distributed generation systems; in Chapter 3, parallel operation of inverters in distributed generation systems; in Chapter 4, power converter topology for distributed generation systems; in Chapter 5, voltage and current control of a three-phase fourwire distributed generation in island mode; in Chapter 6, power flow control of a single distributed generating unit, in Chapter 7, robust stability analysis of voltage and current control for distributed generation systems; in Chapter 8, PWM rectifier control for three-phase distributed generation system; and in Chapter 9, MATLAB Simulink simulation testbed. In this book, these coordinated control techniques will be presented using a MATLAB Simulink simulation testbed. Throughout the book, we will provide the simulation testbeds used for each chapter in Chapter 9. The instructors can use each chapter to study mathematical modeling with its supporting MATLAB testbed, as well as to provide for students with control projects.
