Abstract:
1. An operating method of a redox flow battery system comprising a wind power generator, a redox flow battery annexed to the wind power generator, and an AC/DC converter connected to the redox flow battery, wherein: an output of the wind power generator within a certain period of time in the past is subjected to a first averaging process, a present output value of the wind power generator is subtracted from the output value obtained by the first averaging process, and an input/output command value to the AC/DC converter is determined from the resulting value, the input/output command value is subjected to a variation computing process to find variation without any consideration of a sign of the input/output command value, the resulting value obtained by the variation computing process is further subjected to a second averaging process, and an output command value for a pump to circulate electrolytic solution of the redox flow battery is determined based on the result of the second averaging process.
