Judgment method and system for active participation of wind power and energy storage in power system regulation

The invention discloses a judgment method for active participation of wind power and energy storage in adjustment of a power system. The method comprises the following steps: acquiring data information of a target power system; calculating the frequency change rate of the target power system before and after new energy access; calculating a virtual inertia difference value and an inertia time constant variable quantity of the target power system before and after the fan is cut off; calculating a system frequency change rate of the target power system when the fan is cut off and energy storage participates in adjustment; and calculating a wind power active support transient frequency index and a frequency change rate evaluation index when disturbance occurs, and completing judgment of active participation of wind power and energy storage in adjustment of the target power system. The invention also discloses a system for realizing the judgment method for active participation of wind power and energy storage in
