基于事件触发机制的配电网拓扑-状态联合估计
Joint topology and state estimation for distribution networks using an event-triggered mechanism
摘要
Abstract
With the development of advanced measurement infrastructure(AMI)in distribution networks,smart meter data provide abundant user-side information for state estimation.However,existing communication systems struggle to cope with the increasing network transmission and real-time storage demands.To address the communica-tion pressure caused by massive smart meter data,this paper introduces a closed-loop event-triggered mechanism to reduce unnecessary measurement transmissions.Furthermore,the definition of"events"is extended from load fluc-tuations to topology changes.Due to the lack of telemetry data for substation switching devices,their status informa-tion cannot be directly acquired.Triggered measurements are used to formulate a joint topology and state estimation model through generalized state estimation(GSE).Validation on a modified IEEE 13-node test system confirms that the method reduces communication load while achieving accuracy comparable to weighted least squares(WLS).It also identifies faulty switch status.关键词
