This book provides an introduction to electric energy in all of its various forms and applications using examples, theory, and current events. Its scope is primarily technical but complementary topics are included to enhance the breadth and depth of coverage. Using a problem‑oriented, student‑centric approach with engaging discussion and occasional sidebars, the text combines the basic elements of traditional energy conversion with contemporary issues, giving students the background and expertise they need to meet future challenges. New features in this edition: Provides a general perspective on global energy and electricity consumption, world power markets, and country portfolios Provides an overview of North American interconnections and European mains frequency standards, system inertia, transmission networks, and an outline of transmission theory Covers the main features of grid governance in the U.S., N-1 contingency planning, frequency control, forecasting, and ancillary services Reviews K-rated, phase-shifting, solid-state and high frequency transformers, empirical loss relations, transformer markets, and cost of operation Includes case studies on system disturbance events and blackouts, as well as Ukraine’s grid response to relentless drone attacks and shelling from Russia Reviews airborne wind energy systems, electric vehicles, utility-grade battery storage, offshore wind, reactor designs, and space stations Includes household appliance loads and generator options, data centers and AI, and transmission cost estimation Examines challenges of future power operations and systems, including cyber attacks, distribution grid congestion, harmonic distortion, 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 electrification technologies This text is aimed at undergraduates and beginning graduate students in electrical and mechanical engi
