摘要:
配网故障恢复实质上是通过开关操作将失电区域的负荷转移到有剩余容量的联络备用或 可孤岛运行的DG 上,是一种多目标多约束的优化问题。本文介绍了电网电压薄弱环节的识别方 法,在与电源存在通路的区域内通过判断电压薄弱环节,进一步剔除存在越限风险的节点,确定可 恢复区域,对失电负荷进行重要度排序,并基于收益、风险、代价建立配电网停电恢复策略的优化模 型,采用启发式算法进行求解,得到恢复过程中的目标节点和恢复路径。利用算例系统验证了本文 所提方法的合理性。
Abstract:
Fault recovery of distribution network is actually to transfer the load from power loss area to the contact reserve with remaining capacity or the island operated DG through the operation of the switch, whichisamulti?objectiveandmulti?constrainedoptimizationproblem.Inthispaper,theidentificationmethod of the weak link of network voltage is introduced. By way of judging the weak link of voltage in the area with channelwithpowersupply,thenodewiththeriskexceedingthelimitisfurthereliminatedandtherecoverable area is determined. Moreover,the importance of the power loss is sorted,based on the benefit,risk,and cost, the optimization model for the power outage recovery strategy of the distribution network is established.
