摘要：
The power quality and stability of an on-board DC microgrid are related to whether the electrical equipment in the vehicle can work safely and reliably. Aiming at the problem of bus voltage oscillation and instability of on-board DC microgrids under large disturbances, a large-disturbance model of an on-board DC microgrid that considers constant power load and engine-generator is established. Based on the mixed potential theory, the stability criterion of the on-board microgrid is obtained, solving the problem that existing large-disturbance analysis methods are not suitable for on-board microgrids. The influence of important parameters on the response speed and stability of the microgrid are also analyzed. Finally, the stability criterion and the accuracy of the analysis results are verified by hardware-in-the-loop simulation and bench experiments. The results show that the system satisfying the criterion can operate stably under large disturbances. © 2023 China Ordnance Society. All rights reserved.
