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.
Key words: Dc Bus Signaling (DBS) , dc microgrid, distributed control, voltage droop, , ,
