摘要 拓扑结构和功率分流算法是混合储能系统研究的两个重要内容.本文提出了一种基于模块化级联多电平拓扑的混合储能变换器,并且采用了一种特殊的载波层叠调试方法实现模块间的电压均衡.针对混合储能中的功率分流控制问题,本文总结了最经常采用的低通滤波器法的缺点,并在仿真和实验中与一种新的功率分流算法进行了对比.本文在MATLAB\SIMULINK平台上进行了仿真研究,得到了仿真结果,并且在小容量实验平台获得了短时间运行和长时间运行的实验结果.

Abstract:Topology and power sharing algorithm are two important issues in hybrid energy storage research. In this paper, a novel hybrid energy storage topology based on modular multilevel converter is proposed and a modified carrier-cascaded PWM method is used to realize active voltage balance between energy storage modules. In the research of power sharing algorithm, disadvantages of low pass filter method are summarized, which is the most commonly used strategy for power sharing. A novel power sharing strategy is compared to this method by simulation and experiment. Simulation result is gained on MATLAB/SIMULINK platform. Both short time and long time operation experiment result are gained on a low capacity experimental energy storage device.
Key wordsHybrid energy storage    power sharing    active balance    MMC topology
