This new edition highlights physical concepts while also giving necessary attention to mathematical techniques.

The authors develop both theory and modeling from simple beginnings so that you can readily extend these principles to new and complex situations. Software tools, including PowerWorld Simulation, and the latest content throughout this edition aid you with design issues while introducing you to the most recent trends in the field today.

Preface – Power System Analysis and Design

The objective of this book is to present methods of power system analysis and design, particularly with the aid of a personal computer, in sufficient depth to give the student the basic theory at the undergraduate level. The approach is designed to develop students’ thinking processes, enabling them to reach a sound understanding of a broad range of topics related to power system engineering, while motivating their interest in the electrical power industry. Because we believe that fundamental physical concepts underlie creative engineering and form the most valuable and permanent part of an engineering education, we highlight physical concepts while giving due attention to mathematical techniques. Both theory and modeling are developed from simple beginnings so that they can be readily extended to new and complex situations. New To This Edition New chapter-opening case studies bring principles to life for students by providing practical, real-world engineering applications for the material discussed in each chapter. Comprehensively revised problem sets ensure students have the practice they need to master critical skills. Updated Instructor Resources These resources include ● Instructor’s Solutions Manual with solutions to all problems ● Comprehensive Test Bank offering additional problems ● Annotated Lecture Note PowerPoint Slides ● Lesson Plans that detail how to most effectively use this edition ● Updated PowerWorld Simulator Software ● Student PowerPoint Notes New design projects in this edition meet Accreditation Board for Engineering and Technology (ABET) requirements to provide valuable hands-on experience and to help ensure students are receiving an education that meets globally recognized accreditation standards. The latest version of the valuable PowerWorld Simulator (version 19) is included and integrated throughout the text.

Book Review by A. Anderson

Typical power textbook, heavy emphasis on PowerWorld

This was a required text for a graduate course I took. The book is average with lots of PowerWorld examples, but is rather wordy and long-winded. I have tried using it as a desktop reference at work, but have a very hard time using it to find specific answers when I need them.

Bang for the buck: If you want hands-on activities with PowerWorld, this book provides good narrative to the examples that come with the free version of the software. If you need to write your own code, Grainger & Stevenson is more compact and focused.

Review – Power System Analysis and Design

“In my opinion, this textbook is the market leader at this level. I have received consistently good feedback from students regarding this book. The set of worked examples in this book remains to this day one of it best selling points. The introduction of the PowerWorld material in the latest editions was a good move. To me this is a mature text; it is free from factual errors and omissions. The examples are plenty and good. I like the examples which are carried throughout a given chapter. It has great worked out examples. It is well-written and appropriately concise.”

“The book has a good flow and a good pace. The material is very well written academically.”
