Power sector is responsible for about 40% of the total CO₂ emissions in the world and plays a leading role in climate change mitigation. In this study, measures that lower CO₂ emissions from the supply side, demand side, and power grid are discussed, based on which, an integrated optimization model of CO₂ mitigation (IOCM) is proposed. Virtual energy, referring to energy saving capacity in both demand side and the power grid, together with conventional energy in supply side, is unified planning for IOCM. Consequently, the optimal plan of energy distribution, considering both economic benefits and mitigation benefits, is figured out through the application of IOCM. The results indicate that development of demand side management (DSM) and smart grid can make great contributions to CO₂ mitigation of power sector in China by reducing the CO₂ emissions by 10.02% and 12.59%, respectively, in 2015, and in 2020.
电力部门约占全球二氧化碳排放总量的40%，在缓解气候变化方面发挥着主导作用。本研究讨论了从供应侧、需求侧和电网降低二氧化碳排放的措施，并在此基础上提出了二氧化碳减排综合优化模型（IOCM）。虚拟能源是指需求侧和电网的节能能力，与供应侧的传统能源一起，对IOCM进行统一规划。通过应用IOCM，得出了兼顾经济效益和减排效益的能源分配最优方案。结果表明，需求侧管理（DSM）和智能电网的发展可为中国电力部门的二氧化碳减排做出巨大贡献，2015年和2020年分别减少二氧化碳排放10.02%和12.59%。
