随着“光储直柔”的推进建设，低压直流供电系统中的纹波问题受到了广泛关注。相较于交流系统，直流系统的特点是电源及负载分散性更强、电力电子设备占比更高及接口变换器引起的交直流耦合作用强，因此直流系统中纹波问题表现出低频和高频纹波峰峰值都可能较高的特征，进而不能完全适用交流系统中经典的谐波分析和治理方法。为此，进行低压直流供电系统的主要纹波来源分析，揭示了直流源荷引起直流母线电压纹波问题的机理和特征，并针对具有宽频纹波且纹波来源分散的直流系统提出1种混合有源滤波技术，实现对扰动位置不确定、高低频混合情况下的电压纹波问题治理，提升了低压直流供电系统的电能质量水平。仿真结果证明了所提方案的有效性。

With the advancement of the construction of photovoltaic, energy storage, DC and flexibility, the problem of harmonics in a low-voltage DC (LVDC) power supply system has received widespread attention. Compared with those of an AC system, the characteristics of a DC system are that the power supply and load are more decentralized, the proportion of power electronic equipment is higher, and the AC-DC coupling effect caused by interface converters is strong. Therefore, the problem of harmonics in the DC system indicates that both the low- and high-frequency harmonic peak-to-peak values may be high, and thus the classic harmonic analysis and control methods for the AC system are not completely applicable. To this end, the main harmonic sources for the LVDC power supply system are analyzed, and the mechanism and characteristics of the DC bus voltage harmonic problem caused by DC sources and load are revealed. Accordingly, a hybrid active power filtering harmonic voltage control technology is proposed for the harmonic sources of a broadband and decentralized DC system, which achieves the control of harmonics in the case of uncertain disturbance location and high- and low-frequency mixing, thus improving the power quality level of the LVDC power supply system. Finally, simulation results prove the effectiveness of the proposed scheme.
