Summary Large‐capacity photovoltaic ( PV ) systems will be installed in future power systems. According to Japan's energy outlook, the target capacity of PV systems for 2030 is about 50 GW . When large‐volume PV systems are installed in a power system, the reverse power flow from PV systems may cause a surplus of electric power. To utilize the surplus electric power without reduction of PV power generation, the operation of customer equipment such as heat pump water heaters ( HPWH ) according to PV power generation is expected to be one of the solutions. In this paper, a method of cooperative control of customer equipment with PV power generation is proposed, and the effectiveness of the proposed control is evaluated by simulation analyses.
