摘要
直接空气碳捕集是实现碳中和目标过程中不可或缺的负碳排放技术,但其具有吸附剂再生能耗大、投资成本高的缺点。利用可再生能源驱动直接空气碳捕集系统,并对捕捉的CO_(2)进行合理利用,将成为直接空气碳捕集技术应用的重要形式。为此,针对整体系统设备种类多、特性差异大、电-热-碳多能紧密耦合以及可再生出力间歇波动的特点,提出耦合直接空气碳捕集技术的综合能源系统配置-运行联合优化方法,从而实现系统负碳、经济与稳定运行的目标。基于上海冬季、过渡季以及夏季三种季节典型日下的气象条件以及用户电、热负荷需求进行仿真,验证所提系统及配置优化策略的有效性。
Direct air carbon capture is an important technology to achieve negative carbon emissions.However,it has some disadvantages,such as high energy consumption and high investment cost.Using renewable energy to drive the direct air carbon capture process and meanwhile effective using of captured CO_2 provide important pathway for the application of direct air carbon capture technology.To overcome the issues such as multiple equipment with different characteristics,strong coupling among electricity,heat and carbon,and intermittent fluctuations of renewable power sources,a combined configuration and operation optimization method of the integrated energy system coupled with direct air carbon capture technology is proposed to achieve negative carbon,economic and reliable operation of the overall system.The proposed system and configuration optimization strategy are validated by simulations based on the weather conditions and load requirements under three typical days in winter,transition and summer seasons in Shanghai.
