Furthermore, the use of continuous communication in traditional control systems can result in technical and financial challenges. This paper introduces a fixed-time dynamic event-triggered secondary control for islanded microgrids, designed to achieve frequency restoration, voltage regulation and active power sharing within a specified timeframe.
Therefore, in this research work, a distributed Secondary Controller (SC) for an islanded MG is designed considering Communication Time Delays (CTDs). Sufficient delay-independent conditions for the robust stability of a buffer-free distributed averaging proportional integral control scheme are proposed.
Conclusions In this paper, a novel power balance control method for the hybrid multi-source islanded microgrid system is adopted, which can stabilize the DC bus voltage and restore the frequency and voltage amplitude and achieve active power sharing.
Abstract: An adaptive distributed optimal control secondary control scheme under dynamic self-triggered rules is proposed in this paper for AC islanded microgrid to achieve the consistency of frequency, voltage and active power sharing.
