摘要：
In this paper，a quantitative representation of the inertial support capability of wind turbines based on virtual inertia time constant is presented，and then the influence of torque controller parameters on the virtual inertia time constant is analyzed. On this basis，an integrated frequency control strategy combining adaptive droop control and fuzzy adaptive control of the torque controller is proposed to achieve flexible adjustment of the virtual inertia time constant，which can accelerate the frequency recovery while dampening the rapid change of the system frequency and effectively solve the problem of secondary frequency drop. Finally，the effectiveness of the proposed control strategy and the improvement effect on the secondary frequency drop is verified by simulations. © 2023 Science Press. All rights reserved.
