Abstract

In this paper, the improvement of power system stability in the presence of Interline Power Flow Controller and Doubly-Fed Induction Generator is addressed. The control approach used here is based on finite-time sliding mode control, which demonstrates a high level of robustness against parameter variations compared to traditional linear control methods. Due to its resilient structure, this method ensures system stability despite parameter changes, shifts in disturbance location, and reasonable temporal fluctuations in the occurrence of faults. The control technique is implemented on the Doubly-Fed Induction Generator, synchronous generators, and the Interline Power Flow Controller while observing practical constraints. This method has less chattering compared to the sliding mode control, shorter rise and settling times, higher damping speed, and greater robustness against parameter variations. To evaluate the effectiveness of this approach, the IEEE New England 39-bus test system is used, where simulation results highlight the controller’s impact on stability enhancement, even under imposed limitations
