Abstract：In order to make full use of the frequency modulation capability of the wind turbines，considering

that a conventional wind-power coordinated frequency control strategy not only results in some fluctuations in the

frequency of the system，but also requires high energy storage capacity and poor economic efficiency，therefore，

based on the traditional wind storage coordinated frequency control strategy，an active support control strategy for

wind storage coordinated regulation was proposed，which is based on a virtual synchronous generator（VSG）thirdorder model，and the related wind storage collaborative regulation model was built，and the control strategies for wind turbines and energy storage were designed. Based on this，the inertial response and the primary frequency

response of the wind turbine and the energy storage plant to control the frequency were investigated under different control parameters. Through simulation analysis，it can be concluded that this strategy not only approximates the energy storage inverter as a synchronous voltage source，meets the inertia and damping characteristics required by the new energy grid，suppresses system frequency fluctuations，reduces energy storage capacity configuration，but also makes full use of the potential of wind farms to participate in frequency regulation，increasing the frequency stability of the electricity system.
