摘要
区域能源系统中能源站选址和管网布局规划是影响区域能源系统经济性的重要因素。综合考虑能源站选址、管网布局与负荷分布的特点,提出了基于聚类和最短路径算法的站网布局优化方法。首先,将最短路径权重作为聚类相似性度量,建立站网布局结构模型。然后以系统年均经济成本最小为目标,构架优化目标函数。最后以实际工程案例进行仿真分析,验证了该方法的有效性。所提出的方法可以对区域内能源站数量、选址以及管网布局进行综合优化,为区域能源系统站网布局规划提供理论参考。
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,an optimization method for station network layout was proposed based on clustering and shortest path algorithm.First,the shortest path weight was 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 was established.Finally,the effectiveness of the method was 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.
