面向电碳协同的电炉炼钢市场交易与生产调度联合优化方法OA

Under the dual drive of electricity marketization reform and the EU carbon border adjustment mechanism(CBAM),export-oriented electric arc furnace(EAF)steelmaking enterprises are facing the dual pressure of reducing both energy consumption and emissions.How to achieve the electricity-carbon synergy through optimized production scheduling and trading strategies has become a critical research priority.The continuous cross-day production characteristic of steelmaking makes its production scheduling cycles inconsistent with the trading cycles of the spot market,resulting in poor economic efficiency of the formulated strategy.Therefore,this paper proposes a joint trading and scheduling optimization method with electricity-carbon synergy in EAF steelmaking enterprises considering the coordination of long-and short-term decision cycles.Firstly,the EAF steelmaking production scheduling model based on the resource-task network is established.Secondly,a two-stage coordination framework is proposed.In the first stage,the long-term production scheduling plan is optimized using multi-day electricity price and carbon emission factor forecasts,followed by daily slicing with fixed cross-day tasks.In the second stage,based on the production scheduling plan after daily slicing,the day-ahead electricity price and real-time electricity price forecasts are used for rolling optimization and adjusting daily trading and scheduling strategies.Finally,simulations validate the effectiveness of the proposed method in reducing electricity costs and carbon emissions.
