Interconnection of microgrid with utility grid at distribution level using power electronic converter system

With growing concerns of pollution and depletion in conventional sources of electricity generation, application of renewable energy sources is gaining more importance in recent years. The microgrid consists of renewable energy generation sources, energy storage & local load. Interconnection of microgrids with the utility at distribution level can enhance reliability of electricity with some additional benefits to private electricity generators. This paper proposes a converter system for interconnection of DC microgrids with utility grids at single phase 230 V, 50 Hz. The simulation study of the same system is done in PSIM software.
