Japanese government has declared that the amount of the Photovoltaic cells (PV) will be 53GW by 2030 in national area. It is about 40 times of the amount of PV in 2005. It means that 30 to 40 percent of detached residential houses will have PV systems. It results in many issues such as voltage fluctuation in distribution systems. Voltage in distribution network might rise because of the reverse power flow from many PV systems. PV generation outputs suppression method is being considered to avoid the voltage problem in case of high insolation. However, the output of PV generation should not be suppressed from the viewpoint of efficient energy utilization.It is also probable that fuel cell cogeneration systems will be introduced in many residential houses. In this paper, the operating method of fuel cells for relieving PV generation outputs suppression under high penetration conditions is studied. It is shown that PV outputs can be increased by the operation of fuel cells.
