Abstract: With the continuous increase in the penetration rate of distributed photovoltaics, voltage violation problems in distribution networks are becoming increasingly prominent. Aiming at the problems of slow response speed, complex control, and reduced photovoltaic output in traditional centralized control. A distribution network cluster coordinated voltage control strategy considering the participation of energy storage is proposed. Firstly, a cluster partitioning index that considered the coupling degree within and between clusters and the autonomy capability of cluster voltage is established, and the optimal cluster is formed through an improved community algorithm. Then, cluster voltage control is carried out on both active and reactive levels of the distribution network. Key control nodes of the cluster are selected for voltage regulation. Finally, the proposed cluster partition method and voltage control strategy are simulated on an improved IEEE 33 node distribution network system, and the results show that the voltage of distribution network nodes is effectively controlled.
