Abstract: The new power system has low inertia, and virtual DC motor control can strengthen system inertia and damping. State of charge(SOC) equalization should be considered in multi-energy storage converters to improve system stability. Aiming at the multi-energy storage SOC equalization problem of virtual DC motor control, using the drooping characteristics of the DC motor terminal voltage and armature current, the variable armature resistance control with SOC dispersion and variable equalization coefficient is proposed. In view of the voltage offset problem caused by droop control, the virtual DC motor speed compensation is used. The voltage PI control in traditional virtual DC motor control is replaced by instantaneous power of the bus capacitor to give the system power requirements, which reduces the number of proportional integration links. Taking two batteries as an example, simulated in Simulink, and compared with the armature resistance function of the reference, it can be seen that the proposed control strategy can suppress the DC link voltage drop, adjust the SOC equalization process, and improve its equalization speed and accuracy.
