Investigation of the Storage Battery Station for Effective Utilization of Electric Power Generated by PV Clusters

The voltage of the distribution line in the district where the PV systems are clustered will be raised by reversal power flow from the PVs. Then active power control of the PV systems depresses the output. So, installing storage battery stations in the clustered PV systems is one of the means to solve the problem. Therefore, we investigated proper arrangement and control of the storage battery stations for effective utilization of the electric power generated by the PV clusters. In this paper, by means of computational simulation, we quantitatively revealed the relationship between the total amount of the storage battery capacity, the reduction rate of PV output, and the arrangement of the storage battery stations
