Electric Energy: An Introduction

An introductory review of electric energy using examples, numerical calculations and theory to describe the basic elements of the field. Coverage includes electric infrastructure, the grid, system operations, renewable energy, alternating current circuits, three-phase power, power electronics, blackouts and future power systems. This book provides an introductory review of electric energy using examples, numerical calculations, and theory to describe the fundamental concepts of the field. Its coverage includes electric infrastructure, the grid, system operations, renewable energy, AC circuits, three‑phase power, electrical safety, power electronics, transformers, electric machines, power quality, reliability, future power systems, challenges, and opportunities. This book provides a problem‑oriented, student‑centric approach to electric energy in all of its various forms and applications. Example‑driven with numerous practical problems and engaging discussion, the text combines the basic elements of traditional energy conversion with contemporary topics, giving students the background they need to meet future challenges. Both real and hypothetical data are used in problem solving. New features in this edition: Provides a general perspective on global energy and electricity consumption, trends, demand drivers, and country portfolios Provides an overview of world power markets and transmission networks Covers the main features of grid governance in the U.S., N-1 contingency planning, frequency control, forecasting, scheduling, and ancillary services Includes case studies on system disturbance events and blackouts, including Ukraine’s grid response to massive shelling from Russia Reviews contemporary issues on airborne wind energy systems, electric vehicles, utility-grade battery storage, offshore wind, space stations, and new nuclear reactor designs Includes household load, home generator options, and transmission cost estimation Examines challenges and opportunities of future power operations and systems, including cyber attacks, data centers, distribution grid congestion, harmonic distortion and control interactions, inertia and grid-forming inverters, protection and fault detection, and ramping requirements Special focus on China, the world’s largest electrostate, and its dominant position in electric vehicles, battery systems, high-speed rail, high-voltage transmission, renewable energy, pumped hydro storage, and utility-grade battery storage This text is aimed at undergraduates and beginning graduate students in electrical and mechanical engineering, as well as professionals needing an introductory course in electric energy.
