Optimization of Energy Management Control Strategy for Hydrogen-Electric Hybrid Train
摘要
In order to enhance the stability of the energy regulation of the hydrogen-electric hybrid train and reduce the impact on the train bus of the hybrid system during the energy regulation process, an improved rule-based instantaneous power control strategy is proposed, in which the bus voltage is introduced into the control link to enhance the system stability. The simulation results prove that the optimized control strategy improves the stability of the high-voltage DC link of the hybrid system, avoids the high-voltage surging to the super-capacitor system and the traction system, and extends the service life of the super-capacitor at the same time.
