应用能源系统模型研究了在北京市现有能源环境政策下北京市能源结构变化,分析了电力、供热方面污染物排放量的变化。结果表明:北京市能源结构不断优化,SO2、NOx排放总量在规划期内一直维持在较低水平。 Using the energy system model, this paper studies the energy structure changes of Beijing under the current energy environment policy of Beijing and analyzes the changes of pollutant emissions in electricity and heat supply. The results show that the energy structure of Beijing is continuously optimized, and the total amount of SO2 and NOx emissions has been kept at a relatively low level during the planning period.
