DEMONSTRATION EXPERIMENT FOR VOLTAGE FLUCTUATION SUPPRESSION BY USE OF A LARGE-SCALE BATTERY SYSTEM IN THE MINAMI-SOMA SUBSTATION

抄録

Voltage fluctuations caused by output fluctuations of renewable energies are becoming an issue where a large amount of renewable energies connect to a localized area. We have developed a reactive power control system which calculates reactive power command in order to suppress voltage fluctuations in a localized area utilizing a reactive power output function of a large-capacity battery system. In February 2016, the system was installed in the Minami-Soma substation and demonstration experiments started. The installed system effectively suppressed voltage fluctuations.
