Focusing on the latest development of microgrid operation control technology, this paper combs and summarizes the related research at home and abroad, including the key technologies of microgrid optimization operation, power prediction and virtual synchronous active support. . Microgrid technology integration at the load level has been the main focus of recent research in the field of microgrids. The conventional power grids are now obsolete since it is difficult to protect and operate numerous interconnected distributed generators. A proper investigation of microgrid. . This study presents a comprehensive review of microgrid systems within the U. energy infrastructure, focusing on decentralized energy solutions and their regional implementation. The purpose was to define strategic research and development (R&D) areas for the DOE Office of Electricity (OE) Microgrids R&D (MGRD) Program to support its vision and accomplish its. . microgrid concept, classification and control strategies.
