PV and Energy Storage Siting and Capacity Strategy Based on Dynamic Network Reconfiguration and Cluster Partitioning

For the problem of siting and capacity of PV and energy storage connected to distributed PV distribution network with high penetration rate, a PV energy storage siting and capacity strategy based on dynamic network reconfiguration and cluster division is proposed. The method first proposes a cluster division model considering dynamic reconfiguration for cluster division method, on this basis, a PV energy storage siting and capacity setting model based on dynamic network reconfiguration and cluster division is established, the upper-level planning model takes the equal annual value installation cost, annual operation and maintenance cost, cluster power purchase cost active network loss minimization as the objective function, each cluster DG capacity, ESS capacity and power as the decision variables for The upper-level planning, the lower-level planning model takes network loss minimization as the objective function, and the DG and ESS access capacity and access location of each cluster internal node as the decision variables for the lower-level planning. Finally, the feasibility and effectiveness of the method are verified with the improved IEEE33 node system.
