【摘要】：火力发电是我国温室气体排放量最大的部门,为有效控制该部门排放,应从生产和消费两个环节采取措施。准确核算电力消费引起的温室气体间接排放量是消费端减排的基础,其中电网排放因子会直接影响核算结果。本文总结分析了国内外相关电网温室气体排放因子研究,在已有的区域电网排放因子基础上,结合省级电网电力来源特点,提出了省级电网温室气体排放因子计算方法,以2010年为例计算得出各省电网因子,与区域电网因子进行对比分析,并估算了不同电网因子对核算各省调入电力间接排放的影响。结果表明,2010年省级电网因子与区域电网因子的差距在-67.4%~51.6%,不同电网因子核算得出的各省调入电力间接排放量相差-60.7%~50.2%。与区域电网因子相比,省级电网因子核算结果更为准确,因此更适合用于估算电力间接排放。
[Abstract]:Thermal power generation is the largest greenhouse gas emission department in China. In order to effectively control the emission in this sector, measures should be taken from two aspects: production and consumption. The accurate calculation of the indirect greenhouse gas emissions caused by electricity consumption is the basis of the emission reduction at the consumer side, in which the power grid emission factor will directly affect the accounting results. This paper summarizes and analyzes the research on greenhouse gas emission factors of domestic and foreign power grids. Based on the existing regional grid emission factors and the characteristics of provincial power sources, the calculation method of greenhouse gas emission factors for provincial power grids is put forward. Taking 2010 as an example, the provincial grid factors are calculated and compared with the regional grid factors, and the influence of different grid factors on the calculation of the indirect emission of the incoming electric power from each province is estimated. The results show that the difference between provincial power grid factor and regional grid factor is -67.4% and 51.6% in 2010, and the difference of indirect emission between different power grid factors is -60.7% and 50.2%. Compared with regional grid factors, the calculation results of provincial grid factors are more accurate, so it is more suitable to estimate indirect power emissions.
