For unbalanced three‐phase grid voltage, the traditional Virtual Synchronous Generator (VSG) control cannot overcome the distortion of output current. For this reason, a new control method is proposed in this study. The additional positive‐sequence current adjuster to the traditional VSG control allows the reference current to track the positive‐sequence current, and inhibit the negative‐sequence components. Meanwhile, the oscillations in the power system are decreased. The proposed method has been simulated using Matlab/Simulink and verified experimentally on actual platform. The reliability and effectiveness of the proposed control method have also been compared with the traditional VSG control.
