The evolving nature of power systems has introduced new challenges and opportunities, particularly with the increased integration of distributed generation (DG). This book, titled Multi-Objective Optimal Power Flow Problems Under the Influence of Distributed Generation Scenario, seeks to explore these challenges by focusing on the complex yet critical issue of Multi-Objective Optimal Power Flow (MOOPF). MOOPF problems involve the optimization of multiple conflicting objectives, such as minimizing generation costs, reducing power losses, enhancing voltage stability, and ensuring environmental sustainability. The inclusion of DG adds another layer of complexity due to its intermittent nature, decentralized locations, and varying capacity. This book delves into these multi-dimensional challenges by offering theoretical foundations, as well as practical case studies, to illustrate the impact of DG on power system operations. Intended for both academic researchers and industry practitioners, this book serves as a guide for those working at the intersection of power systems and optimization.
