摘要

针对钢铁企业富余煤气产生、储存、缓冲和使用的周期性变化，以及各周期内蒸汽、电力的供应与需求特点，采用数学规划方法，建立以能源消耗最少、效益最优为目标函数的富余煤气、蒸汽和电力多周期耦合数学模型。模型综合考虑了煤气、蒸汽和电力等能源介质的供需变化以及生产成本、安全等约束，通过ILOG Cplex求解出模型的最优解，获得煤气、蒸汽和电力的最优分配方案，用以指导实际生产。应用表明：模型能使钢铁企业富余煤气、蒸汽和电力等能源介质得到合理、安全和高效的分配，提高了能源使用效率，降低了生产费用。

Abstract

Based on periodical change of generation

storage and consumption of byproduct gases

the features of supply-demand change of steam and electricity for each period

aimed at minimizing energy consumption and optimal benefit of cost-effective

a multi-period coupling model of surplus byproduct gas

steam and electricity in iron and steel works was formulated.The model is implemented by ILOG Cplex and the optimal distribution scheme of byproduct gases

MP steam

LP steam and electricity is obtained.The results indicate: the model can distribute the energy medium reasonably

safely and efficiently

such as surplus byproduct gases

steam and electricity

for improving energy utilization efficiency and decreasing the product cost.
