Multi-objective scheduling of a steelmaking plant integrated with renewable energy sources and energy storage systems: balancing costs, emissions and make-span - data|钢铁制造数据集|能源优化数据集

As an energy-intensive industry, the steel industry grapples with increasing energy costs and decarbonisation pressures. Therefore, multi-objective optimisation is widely applied in the production scheduling of the steelmaking plant. However, the optimal solution prioritising energy savings and emission reductions may lead to impractical or less economically efficient solutions since the processing time requirement (PTR) of steel production orders in real-world production is neglected. A research titled "Multi-objective scheduling of a steelmaking plant integrated with renewable energy sources and energy storage systems: Balancing costs, emissions and make-span" has been published on Journal of Cleaner Production regarding this topic. This study fills the research gap by discussing the impact of PTR on the make-span of the steelmaking process and incorporating it into the optimisation model. Considering the variability of PTR, solving the multi-objective scheduling problem is transformed into the selection from Pareto solutions with different make-spans. To better leverage the temporal flexibility of the steelmaking process, a what-if-analysis-based strategy coupled with the Normal Boundary Intersection method is proposed to generate a series of evenly distributed Pareto solutions. The energy storage system is integrated to improve the time granularity of the steelmaking plant's flexibility. In case studies of the paper, cases were conducted to demonstrate the proposed method for reducing electricity and emission costs.
