This invention discloses a method for suppressing current imbalance and power oscillations based on a virtual synchronous generator (VSG). First, a traditional VSG loop model is established and its parameters are tuned.

A PI controller is used to make the actual grid-connected current track the reference value, and the output modulated wave drives the inverter. This invention can simultaneously suppress the second harmonic oscillations of active and reactive power, improve grid-connected current imbalance and distortion problems, while retaining the active power frequency regulation, reactive power voltage regulation, and inertial support characteristics of the VSG, thus improving the stability and power quality of the new energy grid-connected system.
