Active regulation-based on-load voltage regulation integrated system and control method

The invention provides an on-load voltage regulation integrated system based on active regulation and a control method, and relates to the technical field of power grid voltage regulation control. Calculating a current stability margin and a current power factor corresponding to the voltage regulation action substation according to the gear action and the electric power information, determining a standard stability margin index corresponding to the current power factor from a corresponding stability margin table, and calculating a difference module value between the current stability margin and the determined standard stability margin index; the difference module value is sent to the comprehensive regulation and control master station; and the comprehensive regulation and control master station sorts the difference module values corresponding to the voltage regulation action substations, and voltage regulation operation on the target power distribution nodes is completed in sequence according to the sequence
