Memory-Event-Triggered $H_{\infty }$ Load Frequency Control of Multi-Area Power Systems With Cyber-Attacks and Communication Delays

This article focuses on H ? load frequency control (LFC) of multi-area power systems with cyber-attacks and communication delays by a memory-event-triggered mechanism (METM). The dynamics system components, such as governor, turbine generator, are imitated some circuit systems. To save the precious network bandwidth, METM is constructed to decide which measured data should be transmitted signal. In contrast memoryless ETMs, proposed uses historic over fixed period. guarantee no Zeno behavior, positive constant time waited after each trigger happens. By treating exchanges tie-line between ith area other areas exogenous disturbances, novel decentralized distributed delay modeled represent LFC under deception attacks delays. selecting Lyapunov-Krasovskii functional (LKF) based terms, new sufficient criterions obtained co-design controller triggering parameters for against attacks. Finally, advantages presented method shown via an illustrative case.
