摘　　要：针对煤矿微电网新能源渗透率不断增加,而新能源具有波动性和间歇性等特点,致使系统频率稳定性得不到保障,无法满足供电质量的要求,提出一种基于模型预测控制(MPC)的煤矿微电网多时间尺度优化调度提高电能质量的方法,建立燃气轮机、蓄电池参与的煤矿微电网频率偏差指标最优的目标模型,仿真表明该算法和模型提高了煤矿微电网的供电质量和运行稳定性。In response to the increasing penetration rate of new energy in coal mine microgrid,which have characteristics such as volatility and intermittency,the system frequency stability cannot be guaranteed and cannot meet the requirements of power supply quality,a method of multiple time scales optimization scheduling of coal mine microgrid based on model predictive control(MPC)was proposed to improve power quality.A target model for the optimal frequency deviation index of microgrid with the participation of gas turbines and batteries was established.Simulation shows that the algorithm and model have improved the power supply quality and operational stability of the coal mine microgrid.
