The invention relates to an intelligent soft-switching voltage control method for an active power distribution network based on chance-constrained programming. According to the technical features, theintelligent soft-switching voltage control method comprises the following steps that step 1, branch parameters are separately input according to a selected power distribution system; step 2, a k-means clustering algorithm is used for cluster analysis, and typical scenes for describing the uncertainty of distributed power output and the probability of occurrence of each scene are obtained; step 3,an intelligent soft switching voltage control model of the active power distribution network based on chance-constrained programming is established; step 4, auxiliary variables are introduced for quadratic programming model transformation; step 5, a mixed integer quadratic programming algorithm is used for solving; and step 6, the results of the step 5 are output. The intelligent soft-switching voltage control method solves the problem of intelligent soft switching voltage control strategies under different confidence levels, significantly reduces the number of voltage out-of-limit scenes, and comprehensively improves the operation level of the power distribution network.
