This is a textbook that provides an excellent focus on the advanced topics of the power system and gives exciting analysis methods and a cover of the important applications in the power systems. At the beginning of each chapter, an abstract that states the chapter objectives. And then the introduction for each chapter. All principles are presented in a lucid, logical, step-by-step approach. As much as possible, the authors avoid wordiness and detail overload that could hide concepts and impede understanding. and In each chapter, the authors present some of the solved examples and applications using a computer program. Toward the end of each chapter, the authors discuss some application aspects of the concepts covered in the chapter using a computer program. In recognition of requirements by the Accreditation Board for Engineering and Technology (ABET) on integrating computer tools, the use of MATLAB® and ATP version of the Electromagnetic Transients Program (EMTP) are encouraged in a student-friendly manner. MATLAB® is introduced in Appendix C and applied gradually throughout the book. Each illustrative example is immediately followed by practice problems. Students can follow the example step by step to solve the practice problems without flipping pages or looking at the end of the book for answers. These practice problems test students'' comprehension and reinforce key concepts before moving on to the next section. The book is intended as a textbook for a senior-level undergraduate student in electrical and computer engineering departments, and appropriate for Graduate Students Industry Professionals, Researchers, and Academics The book has more than 11 categories and millions of power readers, and it can use in more than 400 electrical engineering departments at the top of universities all over the world. Based on this information, targeted lists of the Engineers from which specific disciplines will purchase: Electrical engineers; Computer engineers; Power Control engineers; Electronics engineers; Technical power system engineers; Protection engineers; Design engineers; Distribution engineers. The book gives rich information for the industrial engineer and electric control engineer because it is contents more details about control of power flow and the design of distribution networks. The reader will able to modeling, designing, and implement different parts of the power system after he/she finishes reading this book. The book''s strengths: The book using for various academic and industrial levels; The book is giving rich and essential information about power systems and give the fundamental study for the next book (power system protection and control); The book includes a lot of solved examples and problems in each chapter; The results were obtained from the MATLAB program and ATP- EMTP program for different topics; Power system protection and control will include in the next part of the book. After finish reading the book, the reader will be able to manage and control the power system parameters, and it will help him in power station work and control centers. The book will assist the researchers in their field of power system track. The student will be able to Improved coordination between power demand and generation, and Use of modern information technology and program.
