摘　　要：在电力系统中,储能装置作为可控电源,可以平抑新能源发电所带来的能量波动问题。然而,储能装置本身具有的非线性、耦合和时变的特征以及不确定外扰对系统的干扰对储能装置的控制有很大的影响。文章研究了基于线性自抗扰技术对储能装置充放电进行控制。首先建立了储能装置的变流器的数学模型;然后介绍了自抗扰技术,基于自抗扰技术,对储能装置的变流器进行控制;最后设计控制器,并用Matlab软件对其进行仿真。仿真结果表明,双闭环用线性自抗扰技术控制的储能装置的充放电能够满足并网要求。与双闭环均用PI控制的储能装置比较,有更好的动态品质和抗干扰性。In power system,energy storage device as a controllable power source,can solve the fluctuation problem which is brought by new energy power generation. However,energy storage device itself has the characteristics of nonlinearity,coupling and time varying. And there are many uncertain external disturbance on the system. They have a great influence for the energy storage device. This paper studies the technology which is used to control the charging and discharging of energy storage device based on linear active disturbance rejection control technique. First,the mathematical model of converter of energy storage device is established; And then the linear active disturbance rejection control technology is introduced,which is the basis for control of the converter of the energy storage device; at last,the controller is designed and simulated with Matlab software. The simulation results show that double closed loop with LADRC control of energy storage device charge-discharge can meet the requirements of grid. And compared with double closed loop with PI control of the energy storage device,the double closed loop with LADRC control of energy storage device has better dynamic performance and anti-interference.
