A new DC-APF control strategy for DC microgrid
The ripple component of the DC bus voltage will affect the power supply quality of the entire DC microgrid and the safety of equipment operation. Therefore, a new DC active power filter (DC-APF) control strategy was proposed to suppress the DC bus voltage ripple. The ripple detection method and supp...

| description | The ripple component of the DC bus voltage will affect the power supply quality of the entire DC microgrid and the safety of equipment operation. Therefore, a new DC active power filter (DC-APF) control strategy was proposed to suppress the DC bus voltage ripple. The ripple detection method and suppression scheme were optimized based on the analysis of various work modes of DC-APF. A DC bus voltage ripple detection method based on wavelet transform Mallat algorithm was proposed. On the basis of traditional and fuzzy PI control, an improved fuzzy adaptive PI control was proposed to realize the tracking control method of compensation current. A DC microgrid system model with DC-APF was built in MATLAB/Simulink. The simulation results show that, compared with the traditional DC-APF control method, the new type DC-APF control strategy can achieve rapid detection of DC bus voltage ripple and has good ripple compensation effect. The proposed strategy can improve the detection performance and suppression effect of DC-APF on ripple, which provides a new method for ripple detection and suppression in DC microgrid. |
