摘要：为实现"双碳"目标,风电等可再生能源的使用是减少碳排放的根本途径,而碳捕集电厂是降低碳排放的直接手段.但风电具有与生俱来的波动性,风电的骤升骤降会影响碳捕集电厂"电碳耦合"特性,从而对碳捕集效果带来不利影响.而储液罐通过增减自身溶液量可近似地存储释放能量,为解决上述问题提供了可能.该文首先搭建碳捕集电厂数学模型,分析储液罐通过增减溶液量带来的储放能量与碳捕集设备能耗之间的关联,研究储液罐的双向调节能力;然后,提出上爬坡碳超前补偿和下爬坡碳滞后补偿调度策略,双向调节储液罐使碳捕集电厂电碳解耦;接着,构建跟随风电爬坡进行调节的低碳经济调度模型;最后,对含碳捕集电厂、高碳电厂和风电场的电力系统进行仿真,证明所提方法的有效性.
