虑及负荷时变性的配电网故障抢修恢复策略李卿鹏(国网南昌供电公司,江西南昌330000)摘要:配电网的故障抢修与网络恢复需综合考虑电量损失、供电安全、运行经济等因素。首先基于负荷时变,以积分方式表达单节点各时段负荷量,据此择定以恢复负荷价值最大为目标的优先抢修故障点。其次以电压偏移和网损的加权和最小为考量,兼顾拓扑约束和电气量约束,构建故障修复后网络重构模型。再次将二进制粒子群算法与节点分层、环网编码等技术融合,给出抢修与恢复的交替式递进流程。最后以算例实证,表明由于对负荷时变进行了充分考量,因此抢修位次和恢复策略全局最优。关键词:配电网;负荷时变;网络重构;故障抢修中图分类号:TM732DOI:10.19768/j.cnki.dgjs.2022.24.059RestorationStrategyofDistributionNetworkConsideringTimeVaryingLoadLIQingpeng(StateGridNanchangPowerSupplyCo.,Ltd.,Nanchang330000,China)Abstract:Thepowerloss,powersupplysafety,operationeconomyandotherfactorsshouldbeconsideredinthefaultrepairandnetworkrecoveryofdistributionnetwork.Firstly,basedontheloadtimevariation,theloadofeachperiodofasinglenodeisex-pressedintheformofintegrals,andthepriorityrepairfaultpointswiththegoalofrestoringthemaximumloadvalueareselectedaccordingly.Secondly,consideringtheweightingandminimizationofvoltageoffsetandnetworkloss,consideringthetopologyconstraintandelectricalquantityconstraint,thenetworkreconstructionmodelafterfaultrepairisc...
