Abstract

In this paper, the problem of high communication burden in the secondary control of islanded microgrids is investigated, and a new dynamic event triggering mechanism is proposed to schedule the communication between microgrids not only to regulate the voltage and frequency that cannot be controlled by the drop control to the desired values, but also to avoid the use of global information. Compared with the existing research results, the linear matrix inequality is used to design the ideal triggering mechanism and control protocol, and the proposed triggering mechanism involves internal dynamic variables, which dynamically adjusts the triggering thresholds, enlarges the lower limit of the event triggering interval, and drastically reduces the number of communication times among the controllers. Since the control scheme is fully distributed, there is information exchange between each generating unit only with its neighbours, which reduces the requirements of the communication network and improves the stability of the system. These internal dynamic variables play an important role in excluding Zeno behaviour. Finally, the argumentation is obtained through simulation.
