摘　　要：围绕区域建筑的动态冷热电负荷需求,构建燃气轮机耦合土壤源热泵冷热电联供系统的瞬态计算模型。在对负荷及联供系统瞬态模拟的基础上,建立综合考虑系统经济、环境、一次能源消耗量的多目标优化模型,提出一种避免加权系数选取的主观性影响优化结果的方法,既反映供能系统和负荷需求的动态匹配,客观上又符合多目标优化原则。使用该方法对某医院冷热电负荷进行优化,结果表明,最优配置下的耦合系统与土壤源热泵及分供式系统(燃气锅炉加电制冷机组)相比,费用年值节约率(M_(1))分别为12.4%和-3.8%,一次能源节约率M_(2)分别为12.1%和43.5%,环境污染物影子成本节约率M_(3)分别为50.1%和57.2%。Based on the dynamic cooling,heating and power load demands of regional buildings,a transient calculation model of the coupled soil-source heat pump of cooling,heating and electricity supply system for gas turbines was constructed.Based on the transient simulation of the load and installations system,a multi-objective optimization model was proposed considering the economy,environment and primary energy consumption of the system.A method was proposed to avoid subjective influence of weighting coefficient selection on optimization results,this method not only reflected the dynamic matching of energy supply system and load demand,but also accorded with the principle of multi-objective optimization objectively.The optimization results for the dynamic cooling,heating and electricity load of a hospital showed that,compared with the soil-source heat pump system and the subsupply system(gas-fired boiler and electric refrigerating unit),the annual cost saving rate(M_(1))was 12.4%and-3.8%respectively,the primary energy saving rate(M_(2))was 12.1%and 43.5%respectively,and the shadow cost saving rate(M_(3))of environmental pollutants was 50.1%and 57.2%respectively.
