Event-Triggered H∞ Consensus Secondary Voltage Control of AC Microgrids With Sampling Data

In this article, a distributed event-triggered $H_{\infty}$ consensus control strategy is proposed for secondary voltage control of microgrids (MGs) to reduce communication and computational burden. The event-triggered is implemented based on periodic sampling. By using the Lyapunov method to design the triggering conditions and sampling period of the distributed generators (DGs), DGs only communicate with their neighbors under certain specific event conditions, and the event triggering conditions are only calculated at the sampling time. Therefore, it avoids continuous communication and the calculation of continuous event-triggered conditions, thereby reducing the communication and computational burden. The simulation results demonstrate the effectiveness of the control strategy.
