摘　　要：高比例的可再生能源并网给电力系统运行带来了巨大挑战,灵活调节工业负荷是解决这一问题的有效手段之一.钢包精炼炉(LF)用电量大且生产节奏灵活,是一种重要的灵活性调节资源.然而,LF负荷灵活性的大小及其影响因素尚不清晰.因此,本研究中综合考虑LF与上下游设备(转炉和连铸机)之间的相关性,提出了LF作为可削减负荷的灵活性评估方法,采用最大可削减负荷量指标评价LF的灵活性水平,然后分析库存转炉钢水量等因素对LF灵活性的影响.The high penetration of renewable energy has brought huge challenges to the operation of electric power systems. The flexible adjustment of industrial loads is an effective way to address this problem. Ladle furnaces(LFs) in the iron and steel industry is electricity-intensive and flexible in production rhythm, which is a typical flexibility source. However, the magnitude and influencing factors of the flexibility of LFs remains unclear. To fill this gap, in this study, a model for quantifying the flexibility of LFs as cuttable load is established by considering the interconnection between LFs and the upstream/downstream devices(i.e.basic oxygen furnace and continuous caster). The maximum cuttable capacity is used to identify the flexibility level of the LFs. The related factors, such as the inventory molten steel, are analyzed.
