Foundations Of Smart Grids

This book offers a rigorous yet intuitive foundation for understanding modern electric power systems and their transition to smart grids. It bridges classical power engineering principles with today's grid challenges, prioritizing first-principles reasoning, physical insight, and mathematical clarity, its scope covers the historical evolution of electricity, analytical modeling of electrical systems, energy, power, efficiency, harmonics, and multiphase operation, forming the conceptual core for grasping intelligent, data-driven, power-electronics-dominated grids. Core topics include single-phase, two-phase, and three-phase systems; sinusoidal and non-sinusoidal conditions; harmonic distortion and power quality; transmission efficiency; and transformers' role in long-distance delivery. These fundamentals connect to the smart grid paradigm, where sensing, control, communication, and power electronics enhance efficiency, reliability, resilience, and renewable integration. Analytical derivations are enriched with historical context, examples, and engineering interpretations linking theory to real-world behavior. This book provides a coherent, physically grounded introduction to smart grids for senior undergraduate and graduate students in electrical/power engineering, and practicing engineers.
