Sub-Synchronous Oscillation Suppression Based on VSG Virtual Impedance Feasible Domains

[Objective] The virtual synchronous generator (VSG) system exhibits negative damping characteristics under weak grid connection, which triggers subsynchronous oscillations and leads to system instability. The virtual impedance can effectively suppress the sub-synchronous oscillations, but different...
