1. A method for controlling an energy storage system (ESS), the method comprising:
an operation of analyzing energy information of an area for which a peak power load is to be calculated received from a plurality of clients included in the area;
an operation of generating, based on an analysis result, scheduling control information for controlling the ESS connected to the plurality of clients on a daily basis, the operation of generating the scheduling control information comprising an operation of generating, based on a threshold value at which a power conversion system (PCS) included in the ESS is capable of converting power and an energy consumption pattern in the area included in the analysis result, the scheduling control information for controlling charging and discharging of the ESS;
an operation of determining, based on the scheduling control information, whether to generate real-time control information for controlling the ESS on a basis of a predetermined control time period;
an operation of correcting, based on the real-time control information, the scheduling control information; and
an operation of controlling the ESS based on the scheduling control information,
wherein the peak power load is an amount of peak power supplied to the area by a power backbone network that supplies power to the area, and
the energy information includes energy consumption information, energy generation information, and energy storage information generated by the ESS.
