Abstract—The purpose of this study is to control active power of fuel cell co-generation system and reactive power of power conditioning system to suppress frequency fluctuation in power system and voltage fluctuation in distribution system caused by variation of photovoltaic power. The governor-free control for fuel cell co-generation system is applied to reduce frequency fluctuation in power system. A method which controls power fluctuation in distribution system for power conditioning system is applied to reduce voltage fluctuation. The authors reveal the effectiveness of the method by a simulation model. The results suggest that fuel cell co-generation system and power conditioning system work to reduce each targeted fluctuation.
