摘　　要：为降低园区综合能源系统的碳排放量,提升园区新能源消纳水平,文中提出一种面向园区综合能源系统的捕碳-储能联合系统优化配置方法。首先,介绍捕碳-储能联合系统的运行原理及配置方法;其次,利用KL散度(Kullback-Leibler divergence,KLD)描述新能源出力的不确定性,从系统投资、运维、弃风光惩罚以及碳交易成本出发,以园区综合能源系统总成本最小为主目标,以捕碳-储能联合系统投资、运维成本最小为子目标,构建园区综合能源系统捕碳-储能联合系统优化规划模型;最后,利用分布鲁棒优化方法对模型进行求解,通过比较不同场景下模型的经济性、碳减排量以及弃风、弃光效果,验证文中所提模型在园区碳减排和新能源消纳方面的优势。In order to reduce the carbon emission of the integrated energy system in the park and to increase the new energy consumption,a novel planning method to optimize the carbon capture-energy storage joint system is proposed in this paper.Firstly,the operating principle and plan method of a carbon capture-energy storage joint system is introduced.Secondly,the Kullback-Leibler divergence(KLD)is used to illustrate the uncertainty of the new energy.Based on this,the optimal planning model of the carbon capture-energy storage joint system for the integrated energy system is proposed from the aspects of system investment,the operation and maintenance cost,the penalties of tripping the wind and photovoltaic power and the carbon trading cost.In the planning model,the overall cost of the integrated energy system is the main goal and the investment and maintenance cost of the carbon capture-energy storage joint system is the sub-goal.Finally,the distributed robust optimization method is utilized to solve the model,and the advantages of the proposed model on carbon emission reduction and new energy consumption are demonstrated by comparing the economy,emission reduction and new energy tripped under different scenarios.
