In order to reduce the high electricity cost of the belt conveyor system in a coal mine, a virtual energy storage model of the belt conveyor system is proposed based on the coal storage ability of silo. Through coordinated control of belt speed, feed rate, silo load rate and arrival time of the train, the virtual energy storage ability of silo is utilized to realize the power balance considering distributed generations in different period in response to the time-varying electricity price. The case study indicates that the optimal scheduling method in this paper can effectively reduce the electricity cost of the belt conveyor by 61.29%, and improve the power consumption level of the distributed generations, which can help realize the green and effective operation of the belt conveyor system.

为降低煤矿带式输送机系统的高电成本，基于筒仓的储煤能力，提出了带式输送机系统的虚拟储能模型。通过对皮带速度，进给速度，筒仓负荷率和列车到达时间的协调控制，利用筒仓的虚拟储能能力，根据电价的变化，实现了考虑不同时期分布式发电的动力平衡。案例研究表明，本文提出的最优调度方法可以有效降低皮带输送机的用电成本61.29％，提高分布式发电的用电水平，有助于实现皮带输送机的绿色高效运行。系统。
