| 摘 要： | 为保证含串联组合型微源的微网并网和孤岛两种运行模式的平滑切换,研究一种以串联组合型微源和超级电容器构成的子系统作为主电源,用飞轮电池保证不间断供电的微网协调控制方法。首先对系统结构进行简要说明。其次分析了微网模式切换时微源和复合储能的控制方法。最后以含两个串联子系统的微网为例进行Matlab/Simulink仿真分析。仿真结果表明,在复合储能的控制作用下,此微网在模式切换中能保持良好的电压和频率稳定性,从而验证了该控制方法的有效性。

| Abstract: | In order to ensure that the series micro-networks interconnection and the islands of two kinds of operation modes can switch smoothly, a coordinated control method of using a sub-system composed of series-connected micro-source and super-capacitor as the main source and the flywheel battery for keeping uninterrupted power supply is studied. First, the structure of the system is briefly described. Secondly, the control methods of micro-source and complex energy storage in micro-grid mode switching are analyzed. Finally, Matlab/Simulink simulation analysis based on the micro-grid with two series subsystem is made. The results show that the micro-grid can be maintained at good voltage and frequency stability in mode switching because of complex energy storage control function, thus the effectiveness of control method is verified. This work is supported by Youth Science Foundation of Gansu Province (No. 17JR5RA345). |
