摘要：
This paper presents a collaborative control strategy based on virtual synchronous generator (VSG) for DFIG's rotor side converter and grid side converter under unbalanced grid voltage. The control strategy of VSG makes DFIG systems have a strong self-regulation ability for frequency and voltage of the network. In the proposed control strategy, the rotor side converter is controlled to achieve the smooth electromagnetic torque, while the grid side converter is controlled to reduce the oscillation of the output power in DFIG system. Finally, the simulation results verify the proposed control method.
