This book explores optimization techniques for modern electric power distribution systems, addressing rising complexity, growing demand, and the integration of new technologies. It begins by outlining key operational challenges, including power quality disturbances, environmental risks, insulation degradation, grounding reliability, and the influence of distributed generation. The chapters then present a structured pathway of solutions: from fault classification using wavelet analysis and lightning protection design, to advanced insulation materials, power quality monitoring, economic dispatch optimization, harmonic mitigation, network reconfiguration, voltage stability improvement, and hybrid microgrid sizing. Blending theoretical foundations with practical simulations and real-world applications, the book bridges academic knowledge and engineering practice. It offers a multidisciplinary perspective spanning power engineering, materials science, computational intelligence, and smart grids. Aimed at students, engineers, and researchers, it not only equips readers with current methods but also points to future directions in AI-driven fault detection, adaptive protection, and intelligent grid management
