With the increasing penetration of renewable energy connected to the grid

distributed power supply is facing multiple challenges. The virtual synchronous generator technology simulates the operating mechanism of synchronous generator

which becomes one of the most effective solutions. Taking the doubly-fed induction generator(DFIG)based wind turbines as the research object

the virtual synchronization control strategy is studied and analyzed. And the virtual synchronous control model is established to make the DFIG-based wind turbines have greater inertia and the ability of supporting frequency and voltage. The improved double-closed-loop control structure of stator voltage and rotor current for the DFIG is proposed

the stator voltage control model and the output impedance model are established as well. According to the problem of power coupling connected to the grid

the DFIG based on the adaptive stator virtual impedance control strategy helps realize the power decoupling. Finally

the experiment verifies the validity of the proposed method.
