N2 - The DC power supply system of more electric aircraft (MEA) has the inherent characteristics of low inertia and small capacity, make it easy to be impacted by the pulsed power loads (PPLs). Aiming at the stability of bus voltage under different flight phases, an extended droop control strategy based on virtual impedance matching is proposed for fuel cell/battery/supercapacitor hybrid power supply system of MEA. In the proposed method, the virtual inductor, virtual resistor and virtual capacitor droop control are adopted for fuel cell, battery and supercapacitor respectively, enabling the load power to be automatically divided into high-frequency, intermediate-frequency and low-frequency parts. Thus, the power demand could be compensated by each power supply units respectively, according to their output characteristics. The simulation results verify the correctness and validity of the proposed strategy.
