POWER STORAGE SYSTEM FOR POWER SYSTEM

摘要

PROBLEM TO BE SOLVED: To provide a power storage system for a power system capable of efficiently controlling a storage battery of each user, and furthermore efficiently controlling the power system by cooperatively controlling the storage batteries of both the power system and the users according to the needs of a supply command station.

SOLUTION: A power storage system for a power system comprises: a storage battery 13 for a power system being installed as such; a virtual storage battery 14 formed by a plurality of batteries 15 of users being governed by a collection/distribution device 16; and a storage battery monitoring controller 12 for controlling the storage battery 13 for the power system and the virtual storage battery 14 according to a command from a supply command station 11. The storage battery 13 for the power system responds at a high-speed to a command from the storage battery monitoring controller 12 so as to perform a charging/discharging control for a frequency adjustment and an economical load distribution. The virtual storage battery 14 responds at a low-speed to a command from the storage battery monitoring controller 12 so as to perform a charging/discharging control for an economical load distribution. Thus, the virtual storage battery 14 composed of the batteries 15 of users and the storage battery 13 for the power system are cooperatively controlled.
