Dynamic Event-Triggered H∞ Load Frequency Control for Multi-Area Power Systems Subject to Hybrid Cyber Attacks

This article aims at designing a dynamic event-triggered $\mathcal {H}_{\infty }$ load frequency controller for multi-area power systems affected by false data-injection attacks and denial-of-service attacks. A scheme, whose threshold parameter varies with objective system states, is employed to make rational use of limited network bandwidth resources improve the efficiency data utilization. Then, taking impacts aforementioned hybrid cyber into consideration, an attractive model established. Whereafter, several sufficient conditions, which can guarantee exponential mean-square stability preset {H} _{\infty performance index studied system, are obtained through utilizing Lyapunov theory. Additionally, desired designed via handling convex optimization problems. Finally, simulation example displayed explain validity proposed method.
