Summary: | The invention discloses a method and system for configuring the energy storage capacity of a power grid under the constraint of frequency safety, which comprises the steps of constructing typical operation modes applicable to time domain simulation of static load fluctuation and a first-level standard fault and a second-level standard fault of the power grid; carrying out time domain simulation inallusion to the three typical modes; analyzing whether the problem of frequency out-of-limit exists or not under the current energy storage configuration capacity of the power grid in allusion to thesimulation result; respectively carrying out iterative simulation to obtain the minimum energy storage capacity under the primary frequency modulation and emergency control requirements of the powergrid; and determining the minimum configuration capacity of energy storage under the constraint of frequency safety of the power grid. The minimum energy storage capacity configuration requirement forensuring the frequency safe |
