Observer-Based Sliding Mode Load Frequency Control of Power Systems under Deception Attack

This study investigates the observer-based sliding mode load frequency control for multiarea interconnected power systems under deception attack. By introducing observer and combining it with system state equation, expression of error is obtained. A surface proposed to make sure be stable. Then, equation derived. The asymptotic stability whole proved by using linear matrix inequality (LMI) technique Lyapunov theory. Furthermore, a law ensure that attacked can reach stable position. Numerical simulation results are presented support correctness results.
