Abstract：Active management used on distributed energy resources (DERs) can reduce the negative effect caused by the intermittent and randomness of its power output, but it also puts forward higher requirements on the voltage control in the distribution network at the same time. In this paper, the characteristics of voltage control of active distribution network are introduced at the beginning, the network structure of active distribution network is described by graph theory. A dual-stage voltage control method in active distribution networks is put forward, which regulates the voltage within specified range by optimizing reactive power output of different DERs in the system. Finally, the effectiveness and practicability of the proposed method are verified by case studies in 8- bus and 30-bus distribution systems.
