基于最优匹配回路功率的配电网拓扑辨识方法
A topology identification method of distribution network based on optimal matching loop power
The topology of the distribution network often changes during routine maintenance, change and expansion. In addition, the real-time measurement data of the distribution network and the number of configured sensors are limited, and the switch lacks real-time telemetry, which causes the topology generator to not effectively obtain the distribution network topology structure. At present, the common topology identification methods are not well adapted to the above characteristics of the distribution network. Therefore, in order to avoid the state estimation distortion of the distribution network caused by serious faults in the distribution network topology, a new topology identification method is proposed. The method determines the possible topologies based on the matching loop power and performs state estimation on the possible topologies based on the common measured values. The topology with the highest matching degree between the state evaluation result and the measured value is a trusted topology, and the topology is the actual topology. The proposed method realizes the quantitative evaluation of the topology, simplifies the topology identification process, reduces the computational complexity of the topology recognition process, and proves the effectiveness and practicability of the method through related case calculations.
