Urban Distribution Network Planning Method Considering Geographic Information based on Improved Prim Genetic Hybrid Algorithm

With the advancement of urbanization in China, urban blocks have higher and higher requirements for landscape, and the power supply mode of overhead lines is gradually being replaced by cable power supply. Compared with the distribution network planning of overhead line power supply, most of them only need to consider the spatial layout of the load. The distribution network planning of cable power supply should consider the urban geographic information, and the cables should generally be arranged along the streets, not only considering the spatial layout of the load, but also considering the impact of the intersection of urban streets on the network planning. This paper presents a method of urban distribution network planning considering geographic information based on improved prim genetic hybrid algorithm. The improved prim algorithm and improved genetic algorithm are used to plan the network of urban distribution network including street intersections. Firstly, the adjacency matrix between nodes in the area to be planned is established. Secondly, the improved prim algorithm is used to generate a certain number of population size, and the network planning model of urban distribution network is established. Finally, the improved genetic algorithm is used to solve the distribution network model, and the urban distribution network planning scheme considering geographic information is obtained.
