摘　　要：在调峰和碳交易的政策下,热电联产机组面临更加复杂的背景。为了得到抽凝热电联产机组全工况碳排放特性、收益分布、以及碳交易经济性,为机组参与碳交易应对碳市场波动提供参考,利用EBSILON仿真软件结合Python程序得到机组全工况碳排放分布以及收益组成。结果表明:机组度电碳排放量与负荷呈反比;以电负荷325 MW和150 MW为例,供电碳排放强度从903.54 g/(kW·h)上升到1 015.28 g/(kW·h),碳排放总量与负荷呈正比;调峰收益占比最高可达55%,碳交易收益占比最高可达8%;调峰收益在低负荷占比大,而碳交易收益在高、中负荷占比较大;对比碳价从40元/t变化到90元/t和供电碳排放标准从原来的0.9倍变化到1.3倍,得到供电碳排放标准改变对碳交易收益有更大影响;供电碳排放标准的制定应当结合机组排放水平,过高或者过低都会影响热电联产电厂参与碳交易的积极性。Under the policy of peak shaving and carbon trading, cogeneration units face a more complex background. In order to obtain the carbon emission characteristics, income distribution and carbon trading economy of the traditional extraction condensing cogeneration unit under all operating conditions, and provide a reference for the unit to deal with carbon market fluctuations when participating in carbon trading. Using EBSILON simulation software combined with python program, the carbon emission distribution and income composition of the unit under all operating conditions are obtained. The research results show that the carbon emission kilowatt hour is inversely proportional to the load. Taking 325 MW and 150 MW as examples, the carbon emission intensity of power supply increases from 903.54 g/(kW·h) to 1 015.28 g/(kW·h), and the total carbon emission is proportional to the load;The highest proportion of peak shaving income can reach 55%;The highest proportion of carbon trading income can reach 8%, and the peak shaving income accounts for a large proportion in the low load, while the carbon trading income accounts for a large proportion in the high load. Comparing the change of carbon price from 40yuan/t to 90 yuan/t and the change of power supply carbon emission standard from 0.9 times to 1.3 times, it is found that the change of power supply carbon emission standard has a greater impact on the proportion of carbon trading income. The formulation of power supply carbon emission standard should be combined with the unit emission level. Too high or too low will affect the enthusiasm of cogeneration power plants to participate in carbon trading.
