To address the modeling and control of smart grid renewable energy system into electric power systems, this book integrates three areas of electrical engineering: power system engineering, control systems engineering and power electronics The approach to the integration of these three areas differs from classical methods. Due to complexity of this task, the author has decided to present the basic concepts, and then present a simulation test bed in matlab to use these concepts to solve a basic problem in development of smart grid energy system. 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 a matlab simulation test bed. Each chapter ends with a set of problems and projects. The book is intended be used as textbook for instruction or by researchers. This book can be used as undergraduate text for both electrical and mechanical engineers. The prerequisite for the course is a course in fundamental of electrical engineering.
The first guide to the Design and modeling of smart grid energy systems
As we begin the second decade of the 21st century and approach the problem of global warming, we need to accept a fundamental change in how we create, generate, distribute, and use energy. Creating sustainable energy, thereby reducing or eliminating our carbon footprint and efficiently utilizing available energy resources, is of vital importance. Smart grid renewable energy systems are a revolutionary concept in electrical engineering designed to allow end users control over their individual energy needs by providing them with the means to create, maintain, and distribute energy.
Design of Smart Power Grid Renewable Energy Systems uniquely addresses the design and modeling of smart grid renewable energy systems by integrating three areas of electrical engineering: power system engineering, power electronics, and electric energy conversion systems—with an approach that differs from classic methods. After a brief overview of energy and its evolution to electric power, the author introduces the basic concepts behind power grids, then takes an in-depth look at the modeling of converters in power grid distributed generation systems and the design of a smart power grid system. Microgrid photovoltaic and wind energy systems are addressed as renewable energy sources. Load flow analysis of power grids and microgrids, and power grid fault studies are the subjects of the text''s final chapters.
In each chapter, Dr. Keyhani presents a key engineering problem and subsequently formulates a mathematical model of the problem followed by a simulation testbed in MATLAB
