The invention relates to an active distribution network zoning decentralized voltage control method oriented to intelligent soft switch, includes the following steps: according to the structure and parameters of the selected active distribution system, taking the access point of the distributed generation as the center of each division area of the power network, and obtaining the voltage variationof each node when the output of the distributed generation changes through sensitivity analysis; The centralized voltage control model of active distribution network oriented to intelligent soft-switching is established. An intelligent soft-switching oriented decentralized voltage control model for active distribution network is established. The decentralized voltage control model of active distribution network is solved by using alternating direction multiplier algorithm until the convergence accuracy is satisfied. The solution is solved. The invention fully considers the influence of the high permeability distributed power supply access, establishes a zoned decentralized voltage control model of an active distribution network oriented to an intelligent soft switch, solves the problem byadopting an alternating direction multiplier method, and obtains a decentralized voltage control strategy of the intelligent soft switch.
