Overview on Micro-grid Technology Research

Microgrid is an effective way for connecting distributed generation to the power grid. Microgrid technology, as a key technology for renewable energy generation and distribution, has attracted more and more attention from countries and regions in the context of the environmental problems and energy crisis now. The development and extension of microgrids can facilitate the large-scale intervention of distributed power generation and renewable energy, and promote the transition from traditional power grids to smart networks. This article introduces the microgrid technology in detail in terms of basic concepts, research status, and key technologies. We combine the domestic and foreign microgrid theory and experimental research results, put forward some suggestions and prospects of microgrid research.
