摘　　要：针对光储系统使用传统比例微分控制自适应能力差、动态响应时间慢、超调量大以及受干扰时母线电压波动大等问题,提出基于模糊自抗扰的混合储能混合控制策略。采用模糊控制器思想对自抗扰控制参数进行在线整定,赋予自抗扰控制器自调节能力;用模糊自抗扰控制替换传统比例微分控制电压环,构成基于模糊自抗扰的共电压环的双闭环控制结构。将传统的比例微分控制和自抗扰控制进行仿真对比,结果表明,所提出的自抗扰控制在启动时几乎无超调,动态响应速度更快,母线电压波动更小。Aiming at the problems of poor adaptive ability,slow dynamic response time,large overshoot and large fluctuation of busbar voltage when the system is disturbed by optical storage system using traditional PI,a hybrid energy storage hybrid control strategy based on fuzzy auto-disturbance rejection is proposed.The fuzzy controller idea is used to adjust the auto-disturbance rejection control parameters online,give the self-rejection controller self-adjustment ability,replace the traditional PI control voltage loop with the fuzzy auto-disturbance rejection control,and form a double closed-loop control structure based on the fuzzy auto-disturbance rejection common voltage loop.Compared with the traditional PI control and auto-disturbance rejection control,the results the system is almost no overshoot when the system is started under this control strategy,the dynamic response speed is faster,and the bus voltage fluctuation is smaller.
