中文摘要：

在有一个 cogeneration 系统的一个综合熨斗和钢植物，再循环精力连续地被搬运进 cogeneration 系统和电连续地被产生，并且他们俩不能很长时间被存储。而且，电的产生和消费是不规则的，它可以引起更意外的不平衡。因此，由优化精力利用的操作安排全部精力系统是一个关键问题，它在这二个系统在生产系统，在 cogeneration 系统的产生电和再循环的精力包括未加工的精力。在这份报纸，为在有一个 cogeneration 系统的综合的铁和钢植物的精力优化的一个改进线性编程模型被建立。改进模型集中于控制整个精力流动并且通过与一个 cogeneration 系统在一个综合熨斗和钢植物优化各种精力分发和利用在在生产系统之间的全部精力系统和 cogeneration 系统安排整个精力消费。改进模型在更高的精力利用，更低的精力费用和更低的污染排出物为最佳的操作条件提供的案例研究表演。

英文摘要：

In an integrated iron and steel plant with a cogeneration system, recycled energy is continuously transported into the cogeneration system and the electricity is continuously generated, and both of them could not be stored for a long time. Moreover, thegeneration and consumption of electricity is irregular, which may bring about more unexpected imbalances. Therefore, it is a crucial issue to schedule the entire energy system by optimizing the operation of energy utilization, which includes the raw energy in the production system, the generation electricity in the cogeneration system and the recycled energy in these two systems. In this paper, an improved Linear Programming model for energy optimization in the integrated iron and steel plant with a cogeneration system is established. The improved model focuses on controlling the whole energy flow and scheduling the whole energy consumption in the entire energy system between the production system and cogeneration system through optimizing all kinds of energy distribution and utilization in an integrated iron and steel plant with a cogeneration system. Case study shows that the improved model offers the optimal operation conditions at the higher energy utilization, lower energy cost and lower pollution emissions.
