| description | With the integration of highly penetrative distributed photovoltaics into the distribution network, the imbalance between PV generation and load power becomes increasingly apparent, resulting in significant voltage security and stability issues in the distribution network. To overcome the limitations of traditional global voltage control and regional voltage cooperative control, a novel two-layer coordinated voltage control strategy, combining regional control and global control, is proposed for active distribution networks. Firstly, an adaptive partitioning of the active distribution network is achieved, without predefining the number of partitions, using the modular function gain change indicator and the Fast Unfolding algorithm. This adaptive partitioning ensures optimal regional control. Secondly, based on the voltage-power sensitivity principle, the reactive power control margin of PV sources is prioritized for regional-level reactive power control at critical nodes experiencing voltage violations. If the reactive power control margin within the region is insufficient, a combination of global-level reactive power control and active power control is employed. Lastly, simulation analysis is discussed by the IEEE 141-node traditional distribution network to confirm the effectiveness of the proposed method. Results demonstrate its ability to reduce the duration of voltage regulation and overcome the limitations of coordinated control range. The proposed method maximizes the utilization of the reactive power control margin of PV sources and significantly enhances PV penetration levels. |
