Abstract：For the dual-motor speed synchronization system, an active hybrid energy storage system composed of batteries and supercapacitors is designed to improve the performance of DC bus voltage control through power division.This paper compares the power distribution between traditional battery energy storage and hybrid energy storage and the DC bus voltage stability in consideration of frequent changes in motor speed and unbalanced load. Through Matlab/Simulink simulation modeling analysis, it is verified that the proposed hybrid energy storage system power frequency division control can improve the system’s ability to respond to power fluctuations, reduce the peak value of battery charge and discharge current, and stabilize the DC bus voltage.
