A low-voltage unipolar type dc microgrid , which includes photovoltaic (PV) arrays, Fuel Cells (FCs), batteries and power electronic interfaces, is presented in this study. In order to provide the plug-and-play feature, a distributed control strategy based on Dc Bus Signaling (DBS) is studied. According to the proposed control strategy, the operations of the dc microgrid are categorized into three modes: batteries charging/discharging, Constant Voltage (CV) generation and FCs discharging. These three kinds of modes can be automatically switched by using DBS. Control methods of converters for different microsources are also addressed. Simulation results are provided to verify the effectiveness of the proposed control strategy.
