The increasing penetration of distributed photovoltaics (PV) into distribution grids has led to a pronounced voltage over-limit issue, posing significant challenges to grid stability and power quality. Given this context, to address voltage management, a partition-based control methodology is proposed that leverages flexibility from load-side resources. Firstly, the double-layer probability fitting is carried out for photovoltaic uncertainty. Secondly, the risk indicators are innovatively proposed, and a dynamic zoning system including risk indicators is constructed. The centralized-distributed hybrid voltage control architecture suitable for dynamic partition is constructed again. Finally, the proposed model and its performance are assessed through simulations on a modified IEEE 33-bus distribution network. The proposed algorithm effectively mitigates voltage deviations and enables flexible, efficient partition-based voltage control in modernized distribution systems.
