The key technologies and analysis of research state of microgrid community

Microgrid (MG) based on renewable energy source (RES) is an important component of the energy development strategy in China. Microgrid community (MGC) is a new product that has resulted from the development of MG and has reached a critical stage. In China, research on MGC currently remains at an early stage. This paper focuses on an analysis of the concept and characteristics of MGC as well as the key technologies involved in it. In addition, this paper discusses the research progress and achievement of the first MGC demonstration project in China-key technologies and a demonstration of the efficient and reliable operation of it. Finally, this paper provides an outlook on the further development and construction of MGC throughout China.
