Abstract

Abstract: With the continuous improvement of global wind power penetration level, the inertia level of power system continues to decline, and due to the influence of wind speed fluctuation, the fluctuation of system frequency is further increased, which restricts the maximum penetration level of wind generation. Therefore, aiming at the influence of wind speed fluctuation on system frequency, a low-order system frequency response model considering wind speed fluctuation is established, and a wind turbine primary frequency regulation control method based on virtual filter is proposed. By adding an additional control loop to the load shedding power controller, on the basis of not affecting the original primary frequency regulation ability of the wind turbine, the influence of wind speed fluctuation on system frequency is suppressed, and the maximum penetration level of wind generation is improved. In addition, in order to measure the improvement effect, a calculation method of maximum penetration level of wind generation considering wind speed fluctuation and frequency constraints is proposed. Finally, the IEEE9 node time domain model with wind turbines is built on Matlab/Simulink, and different simulation scenarios are set to verify the accuracy of the proposed calculation method and the effectiveness of the proposed control method.
