The present disclosure relates to an active distribution network adaptive voltage reactive power control method, which is used for active power or reactive power control in an active distribution network adaptive voltage reactive power control system. The method comprises the steps that when it is detected that the communication between a NC and an MNC is normal, the system uses centralized voltage reactive power control; when it is detected that the communication between the NC and the MNC is abnormal, the system uses distributed voltage reactive power control. The active distribution networkadaptive voltage reactive power control method of the present disclosure can adaptively select centralized or distributed voltage reactive power control to improve control reliability and realize effective coordinated control of the distribution network. The combination of the centralized voltage reactive power control and the distributed voltage reactive power control can control the distributedgeneration and various reactive devices in the active distribution network under the premise of satisfying the basic voltage constraints, thereby reducing the communication data size and reducing thedimensionality of a control variable.
