Considering the interconnection of a large capacity of wind power generation to the utility grid, it is of great concern that its output power change has adverse influences, e.g. frequency fluctuation. There have so far been some research works on the installation of battery energy storage systems (BESS), as a solution to these problems. However, owing to very high cost of the BESS, its capacity should be as small as possible. In this paper, not only the installation of the BESS as one of the measures for suppressing the frequency fluctuation caused by wind power generation, but also heat pump water heater, one of the demand load, is considered. This paper proposes a coordinated control method of the BESS and the heat pump water heater, and evaluates reduction of the required BESS capacity.
