Multi-objective optimization path selection method for power transmission line based on stepping ring gate

According to a multi-objective optimization path selection method of the power transmission line based on a stepping ring gate, multivariate data driving is adopted, regions are classified, virtual topology nodes are selected to construct a virtual topology map, and feasible topology nodes are selected according to a short path shortest optimization method to carry out overall path planning; afterthe virtual topology path is selected, the virtual topology path is selected; a semi-ring domain type stepping ring gate map is constructed between the topological nodes; and the grids are numbered by using a sectional cutting method, optimization screening is performed on the paths by using grid attributes according to grid attribute definitions, a multi-objective optimization function is constructed according to a distance function, a cost objective function and a corner objective function, and collaborative optimization is performed on the power transmission line paths. 本发明的一种基于步进环栅的输电线路的多目标优化路径选择方法，采用多元数据驱动，对地域进行
