Distribution network line interconnection switch distribution point selection method and device and storage medium

The invention relates to the technical field of power distribution network optimization, and discloses a distribution network line interconnection switch distribution point selection method and device and a storage medium. A target power supply scheme set is determined according to a trunk line set of a target substation; taking a tower and cable tapping point as a target endpoint, taking a line segment between two adjacent target endpoints as a corresponding target line segment, and calculating load redundant data corresponding to different schemes in the power supply scheme set to determine a distribution point selection range of the interconnection switch on the distribution network line; performing point distribution in the point distribution selection range according to the number of the target interconnection switches to obtain each alternative point distribution scheme; and calculating the line minimum redundancy of different feeder switch sides under each alternative point distribution scheme, calcula
