Wind power plant frequency modulation method and device, computer equipment and storage medium

The invention belongs to the technical field of wind power plant frequency modulation, and discloses a wind power plant frequency modulation method and device, computer equipment and a storage medium, and the method comprises the steps: determining the number of energy storage frequency modulation gears and the output capability of each gear; when it is detected that the frequency modulation state of the power grid meets a preset frequency modulation triggering state, frequency modulation is triggered; and when the frequency modulation time of the energy storage battery reaches the preset effective minimum time, detecting whether the frequency modulation state satisfies a preset frequency modulation exit state, if not, calculating the current contribution electric quantity of the energy storage battery until the calculated current contribution electric quantity of the energy storage battery is greater than the power grid demand electric quantity in the preset effective evaluation time, enabling the energy sto
