中文摘要:

面对当前电气综合能源系统在新能源消纳、低碳性方面存在不足的问题,在系统中引入碳捕集装置进行优化。首先通过弃风惩罚因子将弃风量转化为弃风成本,以系统运行成本与碳排放量为多目标建立一种含碳捕集的电气综合能源系统低碳经济运行模型,使用法线边界交叉法构造多目标问题的Pareto前沿,并利用模糊隶属度函数选择出综合满意度最大的解作为折中解,其次通过算例对比了三种场景下的优化结果,分析了系统弃风量受电转气原料成本的影响情况,验证了将捕集的CO2作为产气原料能够有效提升电转气的运行效益,增强系统的风电利用率与运行经济性；最后对多目标下碳捕集的运行造成系统经济性与低碳性产生的矛盾关系进行了研究,证明了碳捕集能够有效提升综合能源系统的碳减排能力。

英文摘要:

Facing the situations of poor new energy consumption rate and low-carbonity performance in the integrated electricity and natural gas system, the carbon capture devices are introduced into the system for optimization. In this paper, first, the curtailing wind punishment factor is used to convert the curtailed wind volume into the wind curtailment cost, and a low-carbon economic operation model of the integrated energy system with carbon capture devices is established with the system operating cost and carbon emissions as the multi-objective. The normal boundary intersection method is used to construct the Pareto frontier of multi-objective problems, and choosing solution with greatest comprehensive satisfaction as the compromise solution through fuzzy membership function. Then, the optimization results in different scenarios are compared, and the influence of power to gas raw material cost coefficient on the system operation is analyzed, verifying that using captured CO2 as the gas production material effectively improves the operating efficiency of the power to gas and enhance the new energy consumption capacity as well as operational economy of the system; Finally, in the multi-target scenario, the contradiction between system operating economy and low-carbonity caused by carbon capture introduction is studied, which proves that carbon capture effectively improve the carbon emission reduction capacity of integrated energy system.
