N2 - Limited by the inherent low inertia and small capacity characteristic of the more electric aircraft (MEA) DC power system, the impact of pulsed power loads (PPLs) such as airborne radar can generate bus voltage fluctuations, seriously affecting the quality of power supply. PPLs cannot be supplied by generators alone, and hybrid energy storage system (HESS) could stabilize the bus voltage fluctuations induced by PPLs, thus improve the reliability of the airborne DC power supply system. This paper proposes a virtual resistor and capacitor droop (VRCD) control strategy considering the autonomous recovery of supercapacitor's state of charge (SOC). The proposed strategy adjusts the output characteristics of the converter by designing the parameters of virtual resistors and virtual capacitors, aimed at achieving accurate and efficient power allocation of HESS. The simulation results show that the proposed control strategy could maintain the DC bus voltage stability in different flight phases of MEA.
