Recently, the introduction of photovoltaic generations has greatly increased. The fluctuation of PV output has a large influence on power flow followed by voltage fluctuation. In order to overcome this situation, we introduced a battery system which has ability to control active and reactive power outputs. This battery system is installed into distribution system to reduce short-term voltage fluctuation. This research confirmed effectiveness of the battery system and evaluated battery life cycle. Also, this battery system was installed to Shimoze distribution substation, where 1,000kW PV plant and household PVs are connected. This paper is a summary of this research which covers the result of field test of the battery system and battery life cycle estimation.
