Abstract—Renewable energy sources are attractive for supplying electricity to isolated island power systems. When the penetration rate of Photovoltaic Systems (PVs) becomes large, the electricity demand cannot consume all of the PV output, but the PV output needs to be curtailed. Demand Response (DR) of heat pump water heaters and battery energy storage systems can reduce the curtailment. Waterworks systems are also suitable for DR resources because many of the waterworks systems have large tanks or dams as water storages. In order to utilize the large flexibility of waterworks systems fully, multi-daily coordinated control of the DR resources will be needed. This paper constructs the optimization model of the isolated power system with several DR resources as a first step of making coordinated control method. Comparing the operation of DR resources between 2-weeks optimization and 1-day optimization, the effect of long-term planning is analyzed with 5 PV capacity settings. Simulation results indicate that the suitable rules of DR coordinated control differ according to the seasons and installed PV capacity.
