Resilient and event‐triggered sliding mode load frequency control for multi‐area power systems under hybrid cyber attacks

The attacks on power systems have been happening all the time, and gradually changing from a single attack to hybrid multiple cyber attacks. Such may cause more catastrophic damages security safety of multi-area systems. Here, control problem is analyzed for under Two Lyapunov–Krasovskii functionals are constructed, by utilizing second-order canonical Bessel–Legendre inequality, sufficient conditions derived stability criteria resilient event-triggered mechanism. A bound with H ∞ $H_{\infty }$ performance obtained proper controller synthesized ensure that trajectory can be driven onto prescribed sliding surface. Finally, numerical examples simulated results demonstrate effectiveness correctness proposed scheme.
