为提高综合能源系统的低碳特性和新能源消纳能力,提出一种考虑氢能利用与碳捕集电厂联合灵活运行的综合能源系统源荷低碳优化调度策略。首先,引入溶液存储器和烟气旁路系统,建立碳捕集电厂综合灵活运行模型,针对氢能转换特性建立氢能利用模型,并提出碳捕集电厂-氢能利用的联合灵活运行模型;其次,构建计及价格型、激励型的综合需求响应模型;最后,以最优经济和低碳为目标,构建了综合能源系统低碳经济调度模型。仿真结果表明,考虑碳捕集电厂-氢能利用联合运行模型能有效降低系统碳排放量,实现综合能源系统经济、环保运行。

To improve the low-carbon characteristics and new energy consumption capacity of an integrated energy system(IES),a source-load low-carbon optimal scheduling strategy for IES considering the flexible joint operation of hydrogen energy utilization and carbon capture power plant(CCPP)is proposed.First,an integrated flexible operation model of CCPP is established by introducing solution storage and flue gas bypass system.According to the characteristics of hydrogen energy conversion,a hydrogen energy utilization model is established,and a flexible joint operation model of CCPP-hydrogen energy utilization is put forward.Second,an integrated demand response model considering price and incentive is constructed.Finally,with an objective of optimal economy and low-carbon,a low-carbon economic scheduling model of IES is constructed.Simulation results show that the joint operation model of CCPP-hydrogen energy utilization can effectively reduce carbon emissions from the system and realize the economic and environmental operation of IES.
