Integrated Routing of Medium Voltage Distribution Network Based on Power Supply Unit Partitioning

Due to the complex and difficult problem of planning in medium voltage distribution network, an integrated routing method considering various network structures and corridor costs is proposed. First, the integrated routing planning model considering of trunk line, branch line, interconnection switch and section switch is proposed, which takes the corridor cost into account. Then, in the case of power supply unit with single-loop, the integrated routing method based on improved Kruskal algorithm and discrete particle swarm optimization algorithm is proposed. In the case of power supply unit with multiple-loop, the power supply area partitioning method and the integrated routing method based on the arc partitioning method are put forward. Finally, the model and method are verified to be scientific and practical through the case study.
