摘要: 煤电低碳化改造过程中存在着峰荷时段碳捕集水平降低和碳配额计算与实际应用存在偏差的问题。针对该问题,首先引入氢燃料电池和储氢装置构成综合协调储能系统,改善碳捕集电厂峰荷时段碳捕集水平不足的问题;然后建立碳配额计算模型,使碳配额的计算方法更符合实际应用;最后以系统综合运行成本最低为目标,构建基于综合协调储能系统的碳捕集电厂优化调度模型,并使用Cplex对所提模型进行求解。算例结果表明:碳捕集电厂在优先消纳风电的基础上提高了碳捕集水平和经济性,兼顾了系统低碳性。

Abstract: In the process of coal-fired power low-carbon transformation, new challenges emerge such as the weakening performance of carbon capture level during peak load period, the deviation between carbon quota calculation and actual application, etc. In view of these issues, the paper first introduces hydrogen fuel cells and hydrogen storage devices to formulate a comprehensive coordinated energy storage system, which can improve the insufficient carbon capture level during peak load period of carbon capture power plants; Then, the carbon quota calculation model is established, such that the calculation method of carbon quotas is more in line with practical applications; Finally, by setting the minimization of comprehensive operating cost of the system as the objective function, the optimal scheduling model of carbon capture power plants based on the comprehensive coordinated energy storage system is constructed, and the proposed model is solved using Cplex software package. The calculation results show that the carbon capture power plant can improve the carbon capture level and economy while prioritizing wind power consumption, by taking into account the low-carbon nature of the system.
