Decentralised Droopless Control of Islanded Radial AC Microgrids Without Explicit Communication

A microgrid is a proven effective way to integrate renewable resources. This study presents an innovative control concept for decentralized AC microgrids, which based on the architectural advantage of radial structure. Under proposed concept, power sharing between distributed sources achieved without droop control. Thus need secondary level eliminated. Moreover, use explicit communication replaced in paper by novel coordination mechanism locally measured currents.
