This book explores the shift from traditional centralized power systems to modern active distribution systems through the integration of Distributed Generation (DG). It highlights the growing challenges of fossil fuel depletion, high transmission costs, and environmental concerns, positioning DG as a solution for generating electricity closer to consumers with improved efficiency and reduced emissions.

The study focuses on optimizing the site and size of DG units in radial distribution networks using advanced algorithms like Differential Evolution (DE) and its variants. It applies these methods to standard IEEE bus systems and a real Indian utility system (TANGEDCO) to minimize power losses, voltage deviation, energy costs, and emissions while improving voltage stability and power quality.

The book offers valuable insights for researchers and power system engineers, demonstrating the technical and economic advantages of optimal DG placement. It aims to guide practical implementation for more resilient, efficient, and sustainable power distribution networks.
