The invention discloses an active power distribution network reactive voltage optimization method coordinated with multiple active management means. According to the invention, a global optimization-local adjustment two-stage reactive voltage optimization strategy is adopted. Specifically, according to the operation scheme of the invention, the optimized comprehensive satisfaction degree of the network loss and the voltage deviation is adopted as a target, and elements longer in regulation time scale, such as an on-load tap-changer, a capacitor bank, a contact and sectional switch and the like, are optimized. After that, a minimum voltage volatility index is adopted as a target. Moreover, a model is optimized and solved based on the application of the improved harmony search algorithm. Finally, through the analysis of examples, the reasonability and the superiority of the reactive voltage optimization method are verified.
