基于建立虚拟电厂的水泥厂智能用电策略研究

Study on Intelligent Power Consumption Strategy of Cement Plant Based on Virtual Power Plant

摘要: 随着生产工艺以及自动化程度的不断提高，水泥企业的煤耗指标呈现逐年下降的趋势，但水泥综合电耗仍呈递增趋势，企业用电费用居高不下。在此背景下，建立基于水泥厂中可调节设备的生产用电负荷的数学模型，并且在计及生产工作区环境舒适度的情况下对温控设备用电负荷建模，以空调节约的电能建成虚拟电厂。在此基础上，综合考虑用户的购电成本建立工业智能用电的优化运行模型。最后，以江苏盐城某水泥厂为例分析了工业智能用电管理的优化运行模型的经济性。

Abstract: As the automation degree of production process is increasing day by day, the coal consumption index of cement enterprises has come to decline year by year, but the electric power consumption still shows a trend of increasing with high electricity expenses. In this context, a mathematical model for the production electricity load based on adjustable equipment in cement plant is established. And the electric load modeling of temperature control equipment is taken into account when considering the environmental comfort degree of production area. On this basis, considering the user’s purchasing power cost, the optimal operation model of industrial intelligent power consumption is established. Finally, taking a cement plant in Yancheng, Jiangsu as an example, the economy of the optimized operation model of industrial intelligent power management is analyzed.
