Abstract: Based on the active participation of the distributed generation (DG) and distribution static synchronous compensator in voltage regulation, this paper proposes a voltage support strategy based on zone-division control in the active distribution network. First, the concept of DG voltage support capability distribution is proposed. Second, a specific DG configuration function is designed based on the distribution of voltage support capability, and the configuration scheme of each voltage regulating equipment is given. Then, by analyzing the voltage support capability of each piece of equipment, the voltage support region and joint support region of each piece of equipment is divided, and a voltage support operation strategy based on zone-division control is proposed. Finally, the effectiveness of the proposed method is verified in the IEEE BUS-33 case. The result shows that the proposed strategy can make full use of the potential of DG voltage support, avoid the conflicting actions of various voltage regulation equipment, ensure that the reactive power compensation equipment maintains a certain capacity reserve, and achieve a good voltage regulation effect.
