摘　　要：为推进能源系统低碳清洁转型,促进高比例新能源就地消纳,提出基于碳-绿证互认和电热柔性负荷的含氢多能系统(hydrogen multi-energy system,HMES)源荷低碳经济调度方法。首先,在源侧考虑电解槽制氢过程中的热量散失及余热利用,建立含电解槽热氢联产环节、氢转热电环节和氢制甲烷环节的氢能多环节利用模型,并在荷侧考虑电热负荷的可转移、可削减、可平移以及可替代特性,构建电热联合需求响应模型;其次,考虑碳配额和绿证的互认关系,提出碳-绿证联合交易方法,在HMES目标函数中同时引入奖惩阶梯型碳交易成本和绿证交易成本;最后,以综合成本最低为目标,考虑系统低碳性和经济性,构建HMES源荷低碳经济调度模型。算例仿真设置多个场景进行对比分析,结果表明:所提方法能使HMES综合成本降低25.6%,碳排放量降低39.2%,且实现该系统新能源的全消纳,验证了本文所提方法能有效提高可再生能源的消纳能力,实现HMES的低碳和经济运行。In order to promote the low-carbon and clean transformation of energy system and promote the on-site consumption of a high proportion of new energy,this paper proposes a source-load low-carbon economic dispatch method for hydrogen multi-energy system(HMES)based on mutual recognition of carbon-green certificates and electric and thermal flexible loads.Firstly,on the source side,the heat loss and waste heat utilization during the electrolytic cell hydrogen production process are taken into consideration,and a hydrogen energy multi-link utilization model including the electrolytic cell heat-hydrogen co-generation link,the hydrogen-to-thermoelectricity link and the hydrogen-to-methane link is established;on the load side,the transferable,cuttable,shiftable and substitutable characteristics of electric and heating loads are taken into consideration,and a combined electric and heating demand response model is constructed.Secondly,while considering the mutual recognition relationship between carbon quotas and green certificates,a carbon-green certificate joint trading method is proposed.In the HMES objective function,reward and punishment ladder-type carbon transaction costs and green certificate transaction costs are introduced.Finally,with the lowest comprehensive cost as the goal,the low-carbon nature and economy of the system are taken into consideration,and an HMES source-load low-carbon economic dispatch model is constructed.Multiple scenarios are simulated and compared for analysis,and the results show that the proposed method can be adopted to reduce the comprehensive cost of HMES system by 25.6%,carbon emissions by 39.2%,and achieve full consumption of new energy in the system,verifying that the proposed method can be adopted to effectively improve the consumption capacity of renewable energy and achieve low-carbon and economic operation of HMES.
