摘要：
In this paper, a FC/Bat-based on-board DC microgrid is adopted. The FC provides the average power demand, and the battery provides the instantaneous increased power and absorbs the feedback power through virtual inductance and resistor droop control. Furthermore, the state of charge of the battery is take into consideration. The reference voltage of the battery unit V-ref is adjusted by Delta V, which achieves the control of the charge and discharge current and maintains the stability of the battery SOC. Afterwards, analyze the large signal stability of the FC/Bat-based on-board DC microgrid based on the mixed potential theory. Then the large signal stability criterion is obtained. It is verified by simulation that the virtual resistance and inductance droop control can realize the power distribution and the large-signal stability criterion is correct.
