Optimal Operation of Active Distribution Networks: Congestion Management, Voltage Control and Service Restoration provides researchers and practitioners with a clear and modern understanding of how to optimize the economic, secure and resilient operation of active distribution networks. The book provides case studies, modern implementations and supporting flowcharts and code, along with current research in congestion management, service restoration and voltage control of active distribution networks. Chapter provide an overview of the active distribution network concept, present key approaches for the congestion management of active distribution networks, and cover approaches in uncertainty, coordination of DLMP, scheduled re-profiling, and more. Other sections cover real-time congestion management and service restoration of active distribution networks. Reviews how to optimally operate active distribution networks under normal conditions and demonstrates worked solutions and contingency planning to mitigate unforeseen challenges - Provides clear guidance on optimizing congestion management, voltage control and service restoration in DER-heavy systems - Demonstrates how to implement distributed voltage control in systems using active distribution networks - Provides an extensive body of methods, associated case studies, worked solutions and implementation discussions on how to embed best practices in engineering and research workflows Provides a foundation in active distribution network congestion management, voltage control and service restoration Optimal Operation of Active Distribution Networks: Congestion Management, Voltage Control, and Service Restoration provides researchers and practitioners with a clear modern understanding of how to optimize the economic, secure, and resilient operation of active distribution networks. This book enables readers to conduct and implement "and-based" operating strategies by providing case studies, modern applications, and supporting flowcharts and code. This book outlines a variety of applications for both beginners and advanced practitioners, starting with a clear introduction to the active distribution network concept. The subsequent chapters cover market applications, including multiple-tier demand response, flexible pricing, and congestion management through dynamic tariffs. Electrical control uses are outlined clearly, from double-time-scale distributed voltage control to load and service restoration methods. Providing all the tools needed to build from foundational to advanced applications, this book is an invaluable guide to the operation of active distribution networks for modern, sustainable power.
