Wind power is an important part of sustainable energy development and plays a pivotal role in the background of the ‘Dual Carbon’ goal. In this paper, a wind power grid-connected model based on Permanent Magnetic Synchronous Generator(PMSG) is proposed. The pitch angle of the wind turbine and the waveform of the grid-side currents are controlled by the PI controller in order to realize the tracking of the power frequency and phase of the grid voltages, and eventually achieve the purpose of grid-connection. By utilizing MATLAB/Simulink, the simulation results reveal that the final output currents’ frequency and phase meet the requirements of grid-connection, and the Total Harmonic Distortion(THD) of the current waveform is less than 2%, which represents a high power quality. It can provide reference for efficient and convenient grid-connection of wind power generation.
