Voltage Regulation in a Stand-Alone DC Microgrid

摘要

DC microgrids provide high efficiency for the integration of dc sources and loads. The increasing integration of photovoltaic (PV) source and battery energy storage system (BESS) in distribution systems, as well as the rapid growth of DC loads, make DC microgrids becoming more favorable. This paper presents voltage regulation using droop control method for a DC microgrid consisted of a PV source, a BESS, and DC loads in the stand-alone mode operation. The coordination control between the PV source and the BESS is required to achieve a power balance in the system. The scheme will be tested using PSCAD/EMTDC software.
