摘　　要：作为钢铁厂内典型可中断负荷,热轧负荷在参与调峰等电网调控需求方面潜力巨大。近年来,需求侧电力市场政策相继出台,如何在充分考虑生产特性和调峰服务要求下,评估热轧负荷调控能力是亟须解决的问题。首先,针对热轧负荷多产线、多产品和连续生产的生产特性,建立了考虑电网调控需求的多产线热轧负荷模型。然后,在此基础上,剖析电力调峰市场和热轧环节生产用能优化的关联需求,提出兼顾多产线热轧负荷调峰和成本约束的综合可调能力评估方法。最后,通过仿真算例分析,验证了所提方法的有效性,并分析了热轧负荷参与日内与日前不同调峰市场下的容量和成本及其关键影响因素。As a typical interruptible load in steel plants,the hot rolling load has great potential in participating in the demands of power grid dispatching and control such as peak regulation.In recent years,with the successive introduction of demand-side electricity market policies,it is urgent to evaluate the regulation capacity of hot rolling loads while fully considering production characteristics and peak regulation service requirements.First,according to the production characteristics of multi-line,multiproduct and continuous production of hot rolling loads,a multi-line model of hot rolling loads is established considering the demands of power grid dispatching and control.Then,on this basis,the correlation demand between the electricity peak regulation market and the production energy optimization in the hot rolling process is analyzed,and a comprehensive evaluation method for the adjustable power capacity is proposed,which takes into account both the peak regulation and cost constraints of multi-line hot rolling loads.Finally,the effectiveness of the proposed method is verified through the simulation case analysis,and the capacity,cost and key influencing factors of hot rolling loads participating in intra-day and day-ahead peak-regulation markets are analyzed.
