AI Technical Summary

Technical Problem

Traditional distribution network planning methods are unable to meet the demand for efficient interaction between power sources, grids, and loads, and cannot comprehensively consider the spatiotemporal operation strategy of the primary active distribution system and the hybrid communication networking strategy of the secondary side, thus affecting the planning economy and control performance.

Method used

A method for integrated primary and secondary planning of distribution networks is established. Based on cyber-physical coupling and network graph theory, a distributed control strategy is adopted to construct a two-layer collaborative planning model. The SA-PSO algorithm is used for iterative solution to optimize the location of energy storage and communication terminals, thereby achieving the optimal selection of wired and wireless networking.

Benefits of technology

It enhances the absorption capacity of distributed energy resources in the power distribution network, reduces planning costs, and improves operation and control performance.
