在“双碳”目标背景下，高比例可再生能源并网与化石能源依赖之间的矛盾日益突出。为协调低碳约束与能源安全，提出了一种基于碳捕集与封存(carbon capture and storage，CCS)、电转气和电动汽车协同的虚拟电厂(virtual power plant，VPP)优化调度模型。该模型通过聚合燃气轮机组、热电联产(combined heat and power，CHP)、风电、光伏及电动汽车等分布式资源，构建“减排-转化-效益”一体化框架。首先，利用CCS捕集二氧化碳；其次，通过CCS-电转气利用弃风弃光电能将二氧化碳转化为甲烷，消耗捕集的二氧化碳形成碳循环；最后，聚合电动汽车参与碳市场交易，利用其产生的中国核证减排量(chinese certified emission reduction，CCER)增加收益。基于Matlab/Gurobi的算例分析表明，相较于传统燃气-CHP系统模型，本文所提模型可降低91.3%碳排放(从2 466.90 t降至214.34 t)，降低弃风弃光成本7.145 7万元，提高可再生能源消纳率，并通过售卖CCER使VPP净成本降低了8 209元，总体来说降低了VPP净成本9.661 1万元。研究验证了多技术协同在提升VPP经济性与环境效益中的有效性，可为新型电力系统低碳转型提供理论支撑与实践路径。

Under the background of the “carbon peak and carbon neutrality” goals, the contradiction between the high proportion of renewable energy grid connection and the reliance on fossil energy has become increasingly prominent. To coordinate low-carbon constraints with energy security, this paper proposes an optimized scheduling model for virtual power plants (VPPs) based on the collaboration of carbon capture and storage (CCS), power-to-gas (P2G), and electric vehicles (EVs). This model builds an integrated framework of “emission reduction - conversion - benefit” by aggregating distributed resources such as gas turbine units, combined heat and power (CHP), wind power, photovoltaic power and EVs: Firstly, CCS is used to capture CO₂; Secondly, through CCS-P2G, CO₂ is converted into methane by utilizing the abandoned wind and photovoltaic energy, and the captured CO₂ is consumed to form a carbon cycle. Finally, aggregated EVs participate in carbon market transactions and increase their profits by using the China certified emission reductions (CCERs) they generate. The case analysis based on Matlab/Cplex shows that compared with the traditional gas-CHP system model, the model proposed in this paper can reduce carbon emissions by 91.3% (from 2,466.9 tons to 214.34 tons), lower the cost of wind and solar power curtailage by 71,457 yuan, and increase the consumption rate of renewable energy. And by selling CCER, the net cost of VPP was reduced by 8,208 yuan. Ultimately, the overall net cost of VPP was reduced by 96,611 yuan. The research verified the effectiveness of multi-technology collaboration in enhancing the economic and environmental benefits of VPP, providing theoretical support and practical paths for the low-carbon transformation of the new power system.
