2010年中国电力行业CO2排放量约占总排放量的一半,承担着CO2减排和缓解气候变化的主要责任。首先,简要介绍了中国电力行业CO2排放现状,然后分别从发电侧、需求侧、电网侧对各减排措施的应用和发展进行分析和评价。在此基础上,提出电力行业碳减排综合优化模型,将需求侧和电网侧的节能潜力等效成虚拟能源,并与发电侧的常规能源进行统一规划,获得经济效益和减排效益综合最优的能源配置方案。采用该模型对中国电力行业的发电能源(包括常规能源和虚拟能源)进行综合优化,结果表明,电力需求侧管理项目的推广和智能电网的建设可对中国电力行业CO2减排作出较大的贡献,在电力“十二五”规划的基础上,2015年和2020年可分别减少CO2排放10.0%和12.6%。
In 2010, China’s power industry accounts for about half of the total CO2 emissions and shoulders the primary responsibility for reducing CO2 emissions and mitigating climate change. First of all, the current situation of CO2 emission in China’s electric power industry is briefly introduced. Then the application and development of various emission reduction measures are analyzed and evaluated respectively from the generation side, demand side and grid side. On this basis, a comprehensive optimization model of carbon emission reduction in the power industry is proposed, and the potential for energy saving on the demand side and grid side is equivalent to the virtual energy, and unified planning is made with the conventional energy on the power generation side to obtain the comprehensive economic and emission reduction benefits Excellent energy allocation program. The model is used to optimize the power generation (including conventional energy and virtual energy) in China’s power industry. The results show that the promotion of DSM projects and the construction of smart grid can make a significant contribution to reducing CO2 emissions in China’s power industry Based on the “Twelfth Five-Year Plan” of electric power, CO2 emissions will be reduced by 10.0% and 12.6% respectively in 2015 and 2020.
