Voltage Ripple Suppression Strategy for Modular Cascaded Energy Storage Systems
为抑制模块化级联储能系统在参数不一致工况下的母线电压纹波,提出一种自适应载波移相调制策略.该方法基于频域分析建立纹波矢量模型,通过构建闭合矢量多边形与组间相位协调,消除开关频次及倍频纹波;针对理论无解区间,采用极值寻优配置实现纹波幅值最小化.仿真与实验结果表明,该策略显著降低了母线电压纹波幅值,在电池状态宽范围波动下具有良好的鲁棒性,验证了方法的有效性.
To suppress the bus voltage ripple in modular cascaded energy storage systems under parameter mismatch conditions,an adaptive carrier phase-shift modulation strategy is proposed.Based on frequency-domain analysis and ripple vector modeling,the switching-frequency and double-frequency ripples are eliminated by constructing closed vector polygons and coordinating inter-group phases.For theoretically unsolvable regions,the ripple amplitude is minimized via extremum optimization.Simulation and experimental results demonstrate that the proposed strategy significantly reduces the bus voltage ripple amplitude and exhibits good robustness under wide-range battery state fluctuations,validating its effectiveness.
