Suppression of Voltage Fluctuation by Utilizing Consumer-Side Energy Storage Devices in PV Connected Distribution System

In Japan, PV has been largely installed in distribution system as a clean resource. However, the instability of PV generation leads to the fluctuation of voltage that can't be ignored, and conventional devices are hard to deal with this problem. Battery storage devices are introduced to suppress the voltage fluctuation. Because battery storage devices with power conditioning system can provide perfect control in PV connected distribution system. Besides large-scale BESS, the increasing penetration of customer side energy storage devices like Home Energy Storage System (HESS), Electric Vehicle (EV), and etc. in distribution system is also notable. In this paper, the centralized control of energy storage devices for voltage fluctuation suppression is proposed, and the utilization of customer-side energy devices is verified.
