Abstract The intermittence and randomness of renewable energy output poses challenges to voltage control of distribution network. In this paper, an active distribution network (ADN) reactive voltage partition and control strategy considering microgrid participation is proposed. Firstly, through the power flow calculation, the sensitivity matrix of node voltages is obtained, and condensed clustering algorithm is used to build the control space of microgrid in ADN, which can determine the cluster of controllable nodes dominated by the microgrid. Then, under the framework of the classic automatic voltage control (AVC) system, a new AVC system with participation of the microgrid in flexible and fast voltage control is proposed. The developed AVC system can coordinate the operation microgrid and conventional reactive compensation equipment, realizing quick and flexible voltage control and improving the quality of voltage of ADN. Finally, a simulation model based on IEEE 33-node system is established. The simulation results verify the proposed voltage control strategy.
