This paper proposes a capacitor voltage synchronizing control (CVSC) system for the regulation of full-scale wind power generator-supplied power systems (FWPS). The capacitor combined with the inverter of a full-scale wind power generator (WPG) is controlled with a CVSC system to mimic the rotor dynamics of a synchronous generator (SG). WPGs are enabled to offer inertial response and primary regulation. The generation and load unbalance of a FWPS is reflected by the deviation of capacitor voltages of WPGs. Small-signal analysis was carried out to investigate the oscillatory modes of a FWPS with the CVSC system. Time-domain simulation studies were undertaken on the FWPS, and the performance of the CVSC system was studied in the cases where a load increase and a three-phase-to-ground fault occurred on the FWPS, respectively.
