摘　　要：本文以“内燃发电机组-吸收式制冷机”和“内燃发电机组-直燃机”两种新能源冷热电联供系统为研究对象,分析了系统能流特性,建立了两种系统的全工况模型,提出了经济、能源、环境3个方面的系统性能评价指标,并采用判断矩阵法确定各个指标的权重;在此基础上,建立了针对核心设备容量的多目标优化模型,并采用遗传算法求解,实现了系统容量的优化配置.以济南市某养殖场年模拟负荷作为算例,验证了优化配置方法的可行性,并且分为夏季工况和冬季工况,详细分析了两种系统的工作模式和异同点,综合一次能源年节约率、运行费用年节约率和二氧化碳排放年减少率等指标对比了两种系统的运行特性,相比较于分供系统,基于内燃发电机组与吸收式制冷机的系统评价指标分别提升了13.69%、18.73%、43.93%,基于内燃发电机组与直燃机的系统则分别提升了10.28%、22.68%、47.59%,对新能源冷热电联供系统的优化设计提供了可借鉴的思路和方法.In this paper,RES-CCHP based on internal combustion generating set and absorption chiller and RESCCHP based on internal combustion generating set and direct combustion engine are considered as research objects.First,the energy flow characteristics of the systems are analyzed.The all-working condition models of the two systems are established,and the performance evaluation indexes of economy,energy,and environment are put forward.The weight of each index is determined by the judgment matrix method.On this basis,a multiobjective optimization model for the core equipment capacity is established,and the genetic algorithm is used to solve the model.Finally,taking the annual simulated load of a farm in Jinan as an example,the feasibility of the optimal allocation method is verified.According to the working conditions in summer and winter,the working modes,similarities,and differences of the two systems are analyzed in detail.Considering the annual saving rates of primary energy and operation cost and annual reduction rate of carbon dioxide emission,the operation characteristics of the two systems are simultaneously compared.Compared with the separate supply system,the evaluation indexes of the internal combustion generating set and absorption chiller-based system are increased by 13.69%,18.73%,and 43.93%,respectively,while those of the internal combustion generating set and direct gas turbine-based system are increased by 10.28%,22.68%,and 47.59%,respectively.These results can provide reference ideas and methods for the optimal design of the CCHP system with renewable energy.
