Abstract :
A key feature of microgrid concept is the ability to operate in islanding mode. Under such operating scenario, the distributed generators within microgrid should form a high-quality voltage supply for the load to sustain its normal operation. Power converters, the interface of renewable sources and energy storage systems, are important components of microgrids. The size and the number of the power converters required will depend on the fluctuating power flow within the microgrid. In this paper, we propose a hybrid control architecture to balance the power shared among the multiple interfacing inverters and optimize the system-operating efficiency. Simulation and real-time test results are provided to validate the proposed hybrid control scheme.
