在高耗能企业中采用“系统化节能动态模型控制”技术，将企业电耗分成若干环节，构建各环节的电耗目标函数模型，再将各环节电耗目标函数值作为企业系统目标控制函数中的决策变量，构建企业级电耗目标函数，并进行优化计算与控制，实现企业电耗最小。

In the high energy consumption enterprises, systematic model controlling technology is used for saving energy. Electrical energy consumption of enterprise is divied into some units, and the object function model of electricity consumption of the units is constructed. The individul object function values of the units are the most important variants in the enterprise´s system object function. The object function model of the enterprise´s electricity consumption is constructed. Based on them,the optimum calculation and control are done to realize the minimum of the enterprise´s electricity consumption.
