基于MRAS的飞轮储能系统控制与应用
|
摘要
飞轮储能系统具有能量转化速度快、效率高以及使用寿命长等优势,可平抑风力发电系统输出功率波动。为了减小飞轮储能系统模式切换时对电网的冲击,提出了一种基于无速度传感器(MRAS)的飞轮储能系统控制方法,该控制方法采用滑模变结构解决了传统的MRAS存在的积分饱和初值偏移误差问题,飞轮驱动电机采用双环控制策略。仿真结果表明,飞轮储能系统充放电波形稳定,风电场输出功率平滑效果较理想。该研究可为飞轮储能系统控制方法的优化和风电场功率平滑策略的选择提供参考。
Flywheel energy storage system has the advantages of fast energy conversion,high efficiency and long service life,which can suppress the output power fluctuation of wind power generation system.In order to reduce the impact of flywheel energy storage system mode switching on power grid,a speed sensorless(MRAS)based control method for flywheel energy storage system is proposed.The sliding mode variable structure control method solves the problem of integral saturation initial value offset error existing in traditional MRAS,and the flywheel drive motor adopts double-loop control strategy.The simulation results show that the charging and discharging waveforms of the flywheel energy storage system are stable,and the smoothing effect of wind farm output power is ideal.This study can provide a reference for the optimization of flywheel energy storage sys tem control method and the selection of wind farm power smoothing strategy.
