Abstract

With the continuous expansion of distribution network scale, the real-time performance of distribution network segmentation algorithm is increasingly difficult to meet the requirements of practical engineering. The result of network segmentation is actually to divide a whole into various smaller modules and calculate and solve these small modules respectively. Based on this, this paper adopts a new network segmentation method integrating branch cutting and node splitting. In this way, nodes and branches are operated accordingly. The boundary variables generated by this way include both the voltage on the split node and the current on the cut branch. Using a new model of distribution network - hierarchical topology model, the global optimization problem is transformed into a multi-stage segmentation problem. At the same time, the negative fast division of distribution network is realized by searching for split nodes and cutting branches. The simulation results of an example show that the algorithm is correct, effective and fast.
