Event-based model predictive damping control for power systems with cyber-attacks.

This paper presents a secure model predictive damping control strategy for the wide-area power system (WAPS) under the DoS/deception attacks. Firstly, the model of WAPS under denial of service (DoS) attacks and deception attacks with the event-triggered mechanism (ETM) is established. Then, a wide-area model predictive damping controller is designed to damp out the interarea oscillations in the WAPS induced by cyber-attacks. Wide-area event-based model predictive damping control (WEMPDC) is proposed, by employing the wide-area information, the ETM is utilized to determine WEMPDC to defend against the cyber-attacks, in the meantime input-to-state stable in probability (ISSiP) of the closed-loop system is guaranteed. Furthermore, the validity of the WEMPDC is investigated by two-area four-machine and 16-machine 68-bus system.
