Evaluation Method for Adjustable Power Capacity of Hot Rolling Loads for Peak-regulation Demand
摘要
Abstract
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,multi-product 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.关键词
