摘　　要：为提高蓄电池储能参数优化效果,该文设计基于自抗扰控制器的蓄电池储能参数优化方法。建立蓄电池储能系统模型,采用变分模态分解方法对系统信号分解,将其调节到中心频率上,将蓄电池储能干扰频率作为影响因素,输入到控制器中,采用自抗扰控制器对其调节,不断优化当前状态,实现基于自抗扰控制器的蓄电池储能参数优化。实验结果表明,应用该文方法后,频率以及充放电功率较为稳定,在充放电上的调节时间也较少,同时,有效降低了充电模式下超调量与放电模式下的电压变化量,证明该文方法有效提高了蓄电池储能参数的优化效果。In order to improve the optimization effect of battery energy storage parameters,an optimization method of battery energy storage parameters based on active disturbance rejection controller is designed.The battery energy storage system model is established,the variational modal decomposition method is used to decompose the system signal,and it is adjusted to the center frequency.Its adjustment,continuously optimizes the current state,and realizes the optimization of battery energy storage parameters based on the active disturbance rejection controller.The experimental results show that after the optimization method studied,the frequency and charging and discharging power are relatively stable,and the adjustment time on charging and discharging is also less.At the same time,the overshoot in the charging mode and the voltage variation in the discharging mode are effectively reduced,which proves that the research method can effectively improve the optimization effect of battery energy storage parameters.
