Mathematical modelling and optimization for integrated production and energy system in an iron and steel plant

In this paper, we address a simultaneous optimization problem of integrated production and energy system in an iron and steel plant. We develop a novel multi-period mixed integer linear optimization model incorporating many realistic operational features such as industrial boilers, steam turbines, combined heat and power generation units and waste heat recovery and power generation units. A case study of a real iron and steel plant demonstrates that compared to the realistic operational strategy, the total operational cost is reduced by 6.25 % using the proposed model.
