综合研究了钢铁企业整个能源系统,根据用户的不同性质设计了混合整数线性规划法(MILP)对其煤气分配进行优化从而达到全局成本最小化,解决了钢铁企业副产煤气短时间不平衡问题.案例分析证明,该方法取得很好的优化结果,与前人的方法相比,节约了5.1%的成本.
The whole energy system of iron and steel enterprises is comprehensively studied. According to the different nature of users, the mixed integer linear programming (MILP) is designed to optimize its gas distribution so as to minimize the global costs and solve the problem of iron and steel enterprises short time imbalance. The case study proves that this method achieves good optimization results, saving 5.1% of the cost compared with the previous methods.
