Event-Triggered robust control scheme for sub-synchronous resonance mitigation in DFIG-based WECS

•An event-triggered SMC design to improve the transient stability of DFIG-based WECS during sub-synchronous resonance.•A design that exploits the fast-tracking capability and robustness of the ETSMC and the high current carrying capability of the rotor side converter.•A design that effectively mitigates SSR and ensures the DFIG’s fast recovery from the unstable oscillations.
