摘　　要：利用区间数理论从经济和环境2个方面,对某园区式分布式综合能源系统中包含的天然气冷热电三联供(CCHP)系统和光伏系统2个子系统及整个综合能源系统分别进行具体的效益分析和影响因素的敏感性分析。有效反映了分布式综合能源系统的经济优势和减排能力,以及在运行过程中由于市场和系统本身带来的不确定性因素对系统的影响程度。该研究在一定程度上减少了不确定性对系统运行的影响,为分布式能源系统和综合能源系统的建设与运行提供了经济和环境两方面的参考。Cost-benefit and sensitivity analysis of the park-type distributed system case,which include two subsystems(the CCHP system and the photovoltaic system),are conducted from both economic and environment system. The interval number theory is applied to this research. And it effectively suggests the economic advantages and emission reduction capabilities of the system,as well as the degree of impact on the system due to uncertainties brought by the market and the system itself during operation. In this research,the impact of uncertainty on system operation is reduced to a certain extent while economic and environmental reference is provided for the construction and operation of distributed energy and integrated energy systems.
