Abstract:

This paper is concerned with a resilient load frequency control (LFC) problem for networked power systems against the aperiodic denial-of-service (DoS) attack. First, considering the intermittent nature of the aperiodic DoS attack and the unavailability of the partial system states simultaneously, a switched observer-based time-delay networked power model is established. Second, to save network bandwidth resources, a novel adaptive event-triggering mechanism is designed by applying a switch-adjusting threshold parameter scheme. Then, a switched observer-based PI controller is designed and a piecewise Lyapunov functional analysis approach is developed such that the exponential stability of closed-loop augmented power systems is derived with desired H_{\infty } performance in forms of linear matrix inequality (LMI). Finally, a power system example with IEEE 39-bus is provided to illustrate the effectiveness of the designed schemes.
