Barrier-Based Adaptive Sliding Mode Security Control for Interconnected Power Systems

Year: 2026

Type: article

Abstract: Multiarea interconnected power systems are large-scale cyber–physical infrastructures in which physical dynamics, communication processes, and cybersecurity threats are tightly coupled. This article addresses the load frequency control (LFC) problem for multiarea interconnected power systems under multiple cyberattacks. Considering the nonlinearities and uncertainties inherent in power system dynamics, an interval Type-2 Takagi–Sugeno (T–S) fuzzy model is constructed for system representation. To improve communication efficiency, a memory-based dynamic event-triggered mechanism (MDETM) is proposed, where historical information is incorporated into the triggering condition to adaptively regulate the transmission threshold and reduce unnecessary data updates. Sufficient conditions are established to ensure global exponential stability with a prescribed$\mathcal {H}_{2}$performance level. On this basis, an adaptive sliding mode controller with barrier functions is further developed to enhance robustness against uncertainties and cyberattacks. The effectiveness of the proposed approach is validated through a three-area power system.
