Abstract | The invention discloses an optimization method, device and system for participation of energy storage in low-frequency safety and stability control of a power grid and a storage medium, and the method comprises the steps: obtaining the residual duration of maximum power discharge of the current residual energy storage capacity of each energy storage substation in the power grid and the current energy storage state, classifying the stored energy based on the residual duration and the current state of the stored energy; obtaining the energy storage power, the charging power and the discharging power of energy storage before vacancy of each energy storage substation in the power grid, and calculating the modulation quantity of each type of energy storage based on the energy storage power, the charging power and the discharging power; when the stored energy is modulated, calling each type of stored energy in sequence according to a preset priority; and obtaining the total modulation amount required by the current |
