Wide-area Damping Control for Cyber-Power Systems With Dynamic Event-triggered Mechanism

In this paper, an event-triggered mechanism is introduced to wide-area damping control (WADC) system with time delay. The stability analysis of the closed-loop system with state feedback under dynamic event-triggered mechanism is carried out through Lyapunov-Krasovskii functional. The triggering matrix and controller gain matrix can be jointly obtained by solving LMIs. The simulation in case of short circuit fault shows the effects of trigger parameters on system response and triggering times under static and dynamic mechanisms, which verifies the theoretical claims.
