分布式储能在风／光／储系统中的应用研究

摘要

在独立风/光/储系统中对储能装置采取分布式接入的方案，设计了相应的储能控制器，采用电压外环和电流内环的控制方法控制系统直流母线的电压稳定。在MATLAB/Simulink平台上，对储能系统接入方案及系统储能控制器进行了仿真，结果表明，在储能控制器的有效控制下，分布式储能可以维持风/光/储系统直流母线电压的稳定和系统负荷的可靠供电。%In isolated wind/photovoltaic/storage systems,distributed access is adopted for the energy storage device,a corresponding storage controller is designed,and voltage outer loop and current inner loop control is adopted to control voltage stability of the system DC bus.On a MATLAB/Simulink platform,the access scheme and energy storage controller of the system is simulated.The result shows that,under the effective control of the storage controller,distributed storage (DS)can maintain steady voltage of the DC bus and reliable power supply of the wind /photovoltaic/storage system.
