Protocol-Based Load Frequency Control for Power Systems With Nonhomogeneous Sojourn Probabilities

This article is concentrated on the load frequency control for interconnected multiarea power systems (IMAPSs) with nonhomogeneous sojourn probabilities (NSPs) and cyber-attacks. A generalized framework of NSPs formulated to describe dynamic behavior IMAPSs. To govern variations probabilities, a deterministic switching signal introduced using average dwell-time technique. Essentially, different from existing protocols, an improved event-triggered protocol that relevant quantizer parameter presented, thereby increasing triggering intervals. Furthermore, both denial-of-service deception attacks, which obey Bernoulli distributions, are considered during information transmission. By virtue Lyapunov theory, mean-square exponential stability established. Finally, effectiveness obtained results verified via numerical example.
