Abstract
En 中文
This paper develops an adaptive event-triggered control strategy based on a dynamic uniform quantization mechanism for alternating current (AC) microgrids (MGs) operating under denial-of-service (DoS) attacks. The proposed strategy enhances system resilience against attacks, reduces the communication burden. To balance the communication burden and control accuracy during normal operation, we design a dynamic uniform quantization mechanism with an exponentially decreasing step size. Based on the dynamic uniform quantization step size, an adaptive event-triggered control strategy is proposed. Theoretical analysis confirms that the Zeno behavior is avoided. Simulation results further demonstrate that the proposed method can ensure the output voltage consensus among distributed generators (DGs).
