Abstract
This study develops a robust integral predefined-time sliding mode control (IPTSMC) strategy to mitigate sub-synchronous oscillations (SSO) in doubly-fed induction generators (DFIG) integrated with voltage source converter-based high voltage direct cur-rent (VSC-HVDC) systems. Initially, a comprehensive dynamic model of the DFIG with VSC-HVDC system is formulated. Subsequently, the IPTSMC scheme is designed and implemented in the grid-side converter of the DFIG, aiming to effectively attenuate SSO phenomena. To guarantee convergence within a bounded time irrespective of the initial conditions, the concept of predefined-time stability is incorporated. Rigorous Lyapunov-based analysis is conducted to demonstrate the stability of the closed-loop system under the proposed control and to derive the explicit expression of the predefined upper bound of convergence time. Finally, extensive simulation results are pro-vided, verifying the superior performance, robustness, and effectiveness of the IPTSMC approach in comparison with conventional control methods for SSO suppression in the DFIG with VSC-HVDC framework.
