Hybrid voltage and current control strategy for virtual synchronous generator under unbalanced voltage conditions

open access: yesIET Renewable Power Generation, Volume 19, Issue 1, January/December 2025.
Abstract The traditional VSG strategy does not consider the negative sequence component, which will lead to current imbalance and power oscillation under unbalanced voltage. Several improved control strategies of VSG are usable for operating under unbalanced voltage nowadays. These control strategies usually require a complex PLL (phase‐locked loop) to
