动态事件触发下的孤岛微电网分布式协同控制
Distributed cooperative control of islanded microgrids under dynamic event trigger
摘要
Abstract
To address the secondary control problem of distributed generators in islanded microgrids,this paper pro-poses a distributed cooperative control strategy based on dynamic event triggering mechanism,where each generation unit introduces a dynamic event triggering mechanism to assist communication,thus saving communication resources in the microgrid.This paper proposes an event triggering condition containing internal dynamic variables,according to which the threshold value in the event triggering is dynamically adjusted to effectively reduce the update frequency of the controller.The proposed control scheme is fully distributed,and each generation unit only needs to exchange information between itself and its neighbors,which reduces the requirement for a central controller and a complex communication network and improves the stability of the system.Voltage and frequency deviations due to primary control are eliminated,while Zeno behavior is avoided.Finally,the effectiveness of this control scheme is verified by building an islanded microgrid model in simulation.关键词
