PROBLEM TO BE SOLVED: To provide a control method of a power storage system capable of improving a VI value with a receiving demand kept. SOLUTION: A power storage system is disposed between tunnel ventilation equipment in which a plurality of ventilation fans 2 are driven or stopped sequentially and the required number of ventilation fans are operated, and a system power source 1 of a power system, wherein a power converter 5 performs compensation according to a compensation power command to start operating the prescribed number of ventilation fans 2 added to the defined number of ventilation fans 2 under operation by means of charging power stored in the secondary battery 6 if a demand alarm occurs which is outputted by deterioration of the receiving demand where the receiving power of the ventilation equipment is estimated on an arbitrary time basis when the power converter 5 having a secondary battery 6 on its DC side performs compensation. |
