Dynamic Event-Triggered Based Distributed Secondary Control for Reactive Power Sharing in Islanded AC Microgrids

This paper proposes a distributed secondary controller with a dynamic event-triggered scheme for reactive power sharing in islanded AC microgrids. The controller leverages a dynamic event-triggered scheme to significantly reduce the communication frequency among distributed generators, thereby conserving communication resources while maintaining effective reactive power sharing. Theoretical analysis demonstrates that the proposed control method ensures reactive power sharing and avoids Zeno behavior. The effectiveness of the designed controller is verified through simulations, showing improved performance compared to traditional static event-triggered scheme.
