| 摘 要： | 综合能源系统可实现各类能源的优化利用,有效解决环境污染与能源浪费等问题,具有良好的发展前景。文中重点研究基于冷热电联供(CCHP)系统和热网构建的多区域综合能源系统的规划问题。首先针对各区域CCHP系统之间的环状热网,建立了考虑节点流量平衡、热能—流量约束及热损平衡约束的热网模型。结合CCHP系统能量平衡约束和热网模型,建立了多区域CCHP系统容量协同优化配置的混合整数线性规划模型。最后以天津市某综合区域为例进行仿真分析,结果表明多区域协同规划和运行能大幅提高燃气轮机利用率,降低燃气锅炉配置容量,最小化热能传输损耗,从而显著降低运行费用。

| Abstract: | The integrated energy system able to realize optimal utilization of all kinds of energy and effectively solve the problem of environment pollution and energy waste has good development prospects. The planning of a multi-district integrated energy system based on the synthesis of combined cooling, heating and power(CCHP)and heating network is mainly studied. First, a model of ring heating network between the CCHP systems is developed with the node flow balance, heat-flow constraint and heat loss constraint taken into account. By considering energy balance constraints and the network model, a mixed integer linear programming model for collaborative optimization configuration of multi-district CCHP is established. Finally, simulation analysis is conducted at a comprehensive area in Tianjin. The results suggest that the cooperative planning and operation of multi-district CCHP can greatly improve the operating factor of gas turbine, reduce the capacity of gas boiler, minimize the heat loss during transmission, and thus significantly reduce the operating cost.
