Research on Active Control Method of Double-fed Wind Turbine

With the increasing penetration of wind power in the system, its inherent problems are becoming increasingly prominent. Reducing the impact of fan power fluctuation on the power grid, maximizing the utilization of wind energy, and making large-scale units continuously and reliably connected to the grid is an urgent problem to be solved. Although traditional power vector control can realize decoupling control, DFIG has strong dependence on parameters, so active power control is an urgent research focus. Based on the analysis of the status quo of active power research, the DFIG model is built on the platform of MATLAB/Simulink. By simulating the dynamic processes of different control modes, the influence of key parameter K on power regulation in virtual inertial control with strong inclusiveness is studied. The control mode with better practicability is obtained and popularized by analyzing and comparing its effect.
