摘要
为科学指导区域综合能源系统中能源站的建设数量、位置以及供能管线布局,研究了考虑区域综合能源系统拓扑特性的能源站和管线规划方法。首先总结了区域综合能源系统的拓扑特性,根据城市规划方案和地理信息系统获得可供选择的能源站站址和管线通道。进而基于能流平衡约束和热网特性建立能源系统的拓扑描述模型,以初期投资建设和后期运行成本最小化为目标,建立能源站和供能管线布局规划模型,并利用正交多项式逼近等方法对优化模型进行合理的简化处理。算例分析结果表明所提方法可得到更为经济的规划方案。
In order to scientifically determine the number and location of energy stations and the distribution of energy supply pipelines in regional integrated energy system,the planning method of energy stations and pipelines considering topological characteristics of regional integrated energy system is proposed.Firstly,the topological characteristics of regional integrated energy system are summarized.According to the urban planning scheme and geographic information system,the optional energy station sites and pipeline channels are obtained.Secondly,a topological description model of energy system is established based on energy flow balance constraints and heating network characteristics.To minimize the cost of initial construction and later operation,the layout planning model of energy station and energy supply pipeline is established,and orthogonal polynomial approximation is used to simplify the optimization model.The simulation results show that the proposed method could obtain a more economical planning scheme.
