摘　　要：我国钢铁行业减碳压力大,然而传统高炉长流程冶金碳排放居高不下,氢冶金技术又尚不成熟,因此提出了发展电炉短流程炼钢的中期低碳发展方式。首先,针对具备新能源、储能设备、高炉煤气发电技术以及高炉长流程和电炉短流程两种冶金工序的钢铁工业园区综合能源系统,构建其供用能结构并且给出设备及冶金工序模型;其次,建立考虑碳排放和设备运行成本的园区优化调度模型;最后,在不同的场景中,研究引入新能源、储能设备和高炉煤气发电技术对电炉钢生产比例的影响,以及不同电炉钢比例对园区经济性的影响。算例结果表明,新能源、储能设备和高炉煤气发电技术的引入将提高园区电炉钢比例,降低园区生产运行成本,有效减少碳排放。The iron and steel industry in China is under pressure to reduce carbon emissions;however,the carbon emissions from the traditional blast furnace long-process metallurgy remain high,and the hydrogen metallurgy technology is still in infancy.Therefore,the development of electric arc furnace short-process steelmaking is the low-carbon development approach in the medium term.First,the energy supply and consumption structure of an integrated energy system of the steel industrial community is constructed,with new energy sources,energy storage equipment,blast furnace gas generation technology,and two metallurgical processes:the blast furnace long-process and electric arc furnace short-process.Then,a model of the equipment and metallurgical processes is presented.Second,an optimal dispatch model that considers carbon emissions and equipment operating costs is developed for the community.Finally,the impact of introducing new energy sources,energy storage equipment,and blast furnace gas generation technology on the proportion of electric arc furnace steel production,as well as the impact of different proportions of electric arc furnace steel on the economics of the community,is investigated in different scenarios.The results show that the introduction of new energy,energy storage equipment,and blast furnace gas power generation technology will increase the proportion of electric arc furnace steel in the community,reduce the community's production and operating costs,and reduce carbon emissions.
