Abstract
Disclosed is a method of controlling frequency of a power system by which a frequency of a power system is regulated using high-speed charging and discharging characteristics of a plurality of energy storage systems (ESSs) and a battery state of charge (SOC), the method including: an operation of comparing, by a control unit, first time information and second time information and performing an exit control mode when the first time information (Before_Exit_time) is equal to or less than the second time information (After_Exit_time); an operation of determining, the control unit, an output amount for each ESS for discharging batteries using a battery discharging amount determining function (Exit_control_output( ) function) when a first parameter value (D_time) preset in the exit control mode is a positive value greater than zero and the second time information (After_Exit_time) is equal to or less than a second parameter value (Clear_time); and an operation of discharging, by the control unit, batteries until the frequency is out of a normal range, when an allocated amount of output for each ESS is calculated.
