Abstract

A power control system is connected to a grid to control power supplied to a load. The power control system includes a battery unit configured to give a power charging/discharging function; a distributed generation configured to generate power by consuming fuel; a power conditioning system configured to receive power from the grid and charge the battery unit with the received power, the power conditioning system converting power discharged from the battery unit and power generated at the distributed generation suitably for the grid and supplying the converted power to the load; a controller configured to control the battery unit and the distributed generation such that at least one of the battery unit and the distributed generation supplies power to the load when the load demands reserve power.
