Aiming at the problem of frequency stability caused by large-scale wind power connected to the grid through DC transmission, a design method of key parameters of wind power connected to the grid through LCC-FHMMC to realize non-communication coordinated active energy support is proposed. Based on the synergetics control theory, by selecting the frequency and DC voltage deviation, and the macro variables of wind farm FM standby construction, the collaborative control law of voltage sag coefficient adaptive frequency change adjustment, frequency FM standby adaptive DC voltage and DC current command value change adjustment is designed to realize the active energy support of grid-connected system by using capacitor energy storage and wind farm FM standby capacity. Finally, the LCC-FHMMC grid-connected model of wind power is established in MATLAB/Simulink, and the effectiveness of the synergetics control law is verified by the frequency load disturbance of the power grid. Simulation results show that the proposed strategy can optimize the coordination of wind farm and soft and direct active energy support, optimize the frequency stability of power grid, and optimize the dynamic process of DC capacitance voltage and DFIG pitch Angle recovery.
