The present invention relates to a management method of ESS by means of electricity demand prediction and comprises the steps of: matching (s90) of a characteristic of the same date; extracting (s100) of charge electricity amount of the previous year of a certain date; extracting (s200) of a fluctuation rate in electricity on the basis of population change; extracting (s300) of a change capacity of the charge demand electricity amount on the basis of a facility change; extracting (s400) of a change rate of the charge demand electricity amount on the basis of a temperature variation; predicting (s500) of the demand by calculating the fluctuation rate of the electricity and the charge electricity on the basis of population change and the temperature variation, and the charge electricity of the previous year; detecting (s600) of residual capacity of ESS; selecting (s700) of whether to charge or to discharge on the basis of the residual capacity; determining (s800) of whether the unit price of charge is the lowest or not; and determining (s900) of when the peak time of discharge is. |
