Double-layer zonal voltage regulation strategy for distribution network based on cloud-edge collaboration

Large-scale access of photovoltaic power supply to the distribution network increased the risk of voltage limit violation. To this end, this paper proposes a double-layer zonal regulation strategy based on the framework of cloud-edge association. In the first layer, a network reconfiguration model with the optimal comprehensive index is constructed, which uses the limited network load scenario analysis method (LNSAM) and the reconfiguration scheme reduction method (RSRM). The second layer utilises PV inverters and static var generator (SVG) to control the voltage of the dominant node of the partition in real-time based on the optimised topology in the first layer. Finally, the optimised reference domain boundaries of the voltage of the dominant nodes are obtained by the migration and reproduction algorithm (MARA). By simulating the modified IEEE33 system, the feasibility of the strategy proposed in this paper is verified while realising economical voltage regulation.
