Optimal Planning of Station Network Layout of District Energy System Based on Clustered Site Selection

The location of energy stations and pipeline network layout planning in the district energy system are important factors that affect the economics of the district energy system. Considering the energy station site selection, pipe network layout and characteristics of load distribution, this paper proposes an optimization method for station network layout based on clustering and shortest path algorithm. First, the shortest path weight is used as a cluster similarity measure to establish a network layout structure model. Then aiming at minimizing the annual average economic cost, the optimization objective function is established. Finally, the effectiveness of the method is verified by simulation analysis of actual engineering examples. The proposed method can comprehensively optimize the number, location of energy stations, and pipeline network layout in the region, and provide a theoretical reference for district energy system station network layout planning.
