Abstract
Steam power steam including a variety of energy producers and demand over time, is an essential part of iron and steel companies. Factors of different equipment units, various sums of energy demand in each period, energy prices fluctuations with period and expense of changeover of each equipment unit between periods were taken into consideration respectively in this paper. A mixed integer nonlinear programming(MINLP)model was established, which is multi-period and steam-electricity coupled. The objective function is the sum of cost of energy in steam and power system during whole periods. The global optimal solution will be achieved by LINGO software, The core of which is mathematical programming. Based on the result and analysis of the calculation, it is demonstrated that initial operation condition has great influence on the result of multi-period optimization and LINGO solves this kind of model with high efficiency and reliability. It is analyzed that optimization result is to achieve the lower cost and high economic operation, which could be the basis of production and operation by the administrator.关键词
