Describing the formation, integration, planning, composition, and operation of microgrids, this book explains how local power systems can address limitations in conventional electric power grids, and provides insights into the practical implementation needs and outcomes of microgrid technology. All aspects of microgrid design and applications are covered, including the main technologies involved in microgrids and other local area power and energy systems. The reliability and economic characteristics of microgrid system architecture, energy storage, and grid interaction are explored in depth.
