Abstract
“DC Micro-grid” is a novel power system using dc distribution in order to provide a super high quality electric power. The dc distribution system is suitable for dc output type distributed generations such as photovoltaic and fuel cells, and energy storages such as batteries and electric double layer capacitors. Power is distributed through dc distribution line and converted to required ac or dc voltage by converters placed near loads. Load-side single inverters are connected with transformer in order to share active and reactive power. In this paper, we proposed active and reactive power control methods for load-side inverter. Simulation results demonstrate controlled characteristics of the proposed method.
