Abstract
While a control method is established which can maximize the lifetime of an storage battery based on a SOC capable of maximizing the lifetime of the storage battery under a temperature condition and a wind condition at an electricity generation site and on currently known ones of other operational conditions, a control system is constructed which can feedback to an actual wind power generation and storage battery system. The control system includes a wind power generation and storage battery system, an storage battery operation and deterioration data collection unit for collecting data of the wind power generation and storage battery system, an storage battery operation and deterioration relation assessment unit for assessing a relation between an operation of the storage battery and deterioration thereof based on the collected data, an storage battery operation planning unit for planning such a method of operating the storage battery as to satisfy a necessary lifetime requirement using information obtained by the storage battery operation and deterioration relation assessment unit, and an storage battery operation instruction unit for instructing the wind power generation and storage battery system to operate the storage battery in accordance with the plan of the storage battery operation planning unit.
