冷热电三联供系统配置与运行策略的优化

Integrated Optimization of Scheme and Operation Strategy for CCHP System

对一个冷热电三联供系统的配置与运行策略进行了分析。该系统由燃气内燃机、吸附制冷机和电热泵组成。根据设备容量、数量、性能和分时段能源价格等,在满足应用场合冷热电负荷需求条件下,运用混合整型(0-1)多级目标规划方法,建立了联供系统的优化模型,得到了系统的最优配置和运行策略。该模型三级目标函数包括运行费用最低、各主要设备配置数量最少和实际运行负荷率最大化。应用该模型对一实例进行的分析取得了较好的经济效果。

The scheme and operation strategy of CCHP system is analyzed. The system is mainly consisted of gas engine, adsorption refrigerator and electrically driven heat pump. An integrated optimization model of CCHP system is established by applying the mixed-integer （0-1） multi-objective programming approach under the conditions of those factors such as the capacities, quantities and performance of the equipments as well as the time-of-use rates of energy can simultaneously satisfy the load of power, heating and cooling demands. By solving the model, the optimal scheme and operation strategy of the CCHP system is obtained. The tri-objective functions of the model include the minimum of the operational costs, the minimum of the quantity and maximum of the actual operational load ratio for each kind of main facilities configured. One case was studied on the application of the model and a good economical effect was obtained.
