摘要

Abstract

Traditional active power sharing in microgrids

achieved by the distributed average consensus

requires each controller to continuously trigger and communicate with each other

which is a wasteful use of the limited computation and communication resources of the secondary controller. To enhance the efficiency of secondary control

we developed a novel distributed self-triggered active power-sharing control strategy by introducing the signum function and a flexible linear clock. Unlike continuous communication–based controllers

the proposed self-triggered distributed controller prompts distributed generators to perform control actions and share information with their neighbors only at specific time instants monitored by the linear clock. Therefore

this approach results in a significant reduction in both the computation and communication requirements. Moreover

this design naturally avoids Zeno behavior. Furthermore

a modified triggering condition was established to achieve further reductions in computation and communication. The simulation results confirmed that the proposed control scheme achieves distributed active power sharing with very few controller triggers

thereby substantially enhancing the efficacy of secondary control in MGs.
