摘　　要：以成都某办公楼的“冷-热-电”联供系统为研究对象,在采用eQUEST软件计算该建筑的冷、热、电需求的基础上,构建了实现容量配置和协同运行相关联的双层非线性优化模型,采用模糊满意度方法对其进行求解,最终求得CCHP系统的最适宜配置方案:额定功率330.0 KW的燃气轮机、额定功率500.0 kW的余热锅炉、额定功率1 600.0 kW的溴化锂制冷机、额定功率1 550.0 kW的燃气锅炉和额定功率850.0 kW的电制冷机的组合,该供能方案可以很好地满足办公楼的用能需求。相较于“先配置优化后运行”模型和“先运行优化后配置”模型,系统总成本分别降低了1.17×10^(4)和36.18×10^(4)元,能源利用效率也得到显著提示,体现了很好的应用潜力。双层优化方法的成功应用,可为其他类型建筑供能系统配置运行优化策略的制定提供很好的示范和借鉴。Taking a combined cold,heat and power(CCHP)system of office building in Chengdu,China as a case study,based on the predicted energy requirements provided by the eQUEST software,a bilevel optimization model was built to realize the connection between capacity configuration and coordinated operation of CCHP system.The optimal configuration scheme of CCHP system was the combination of gas turbine(330.0 kW),waste heat boiler(500.0 kW),lithium bromide refrigerator(1600.0 kW),gas-fired boiler(1550.0 kW)and electric chiller(850.0 kW),which met the energy demand of office building.Compared with two types of single-layer optimization models,the system cost was reduced by 11700 and 361800¥,respectively.Meanwhile,the energy-utilization efficiency was improved,which shown a good application potential.The successful application of the bilevel optimization method was capable of providing a good demonstration and reference for optimizing system configuration and operation strategies of other types of building.
