DC-link-stress-aware DVR–supercapacitor scheme for voltage restoration and transient energy stabilization in PMSG wind turbines
Permanent magnet synchronous generator (PMSG)-based wind energy conversion systems (WECSs) are known for their high efficiency and full-scale converter interface and are widely used in variable-speed wind-power applications. However, grid disturbances such as voltage sag and swell degrade terminal-voltage quality and i...
