| 摘 要： | 针对配电网实时量测有限，并且开关、刀闸设备缺乏实时遥信的情况，提出了一种配电网拓扑结构辨识方法——最优匹配回路功率法。该方法基于最优匹配回路功率，寻找出了若干种有可能的配电网拓扑结构，利用相同的量测值在不同的拓扑结构下分别进行状态估计，选择与量测匹配度最好的拓扑结构作为当前的可信拓扑结构。这样，将网络拓扑辨识问题转换成了以量测匹配度好为目标的网络重构问题。算例表明，该方法可行有效。

| Abstract: | The real-time measurements in distribution network are very limited, and it is a technical challenge to identify the topology of distribution network. In this paper, the concept of optimal matching loop power is proposed. Based on optimal matching loop power, an efficient iden-tification method is developed, which can find out several possible topologies. Then, the state es-timator is used to choose the most reasonable topology with the minimal measurement residuals. In the proposed method, the topology identification is converted to the problem of network recon-figuration whose objective is the minimal measurement residuals. Numerical tests prove that the proposed method is potentially applicable to the practice. |
