Abstract:
The load-dependent voltage deviation limits the application of droop control strategy in DC microgrid system. A new droop control method is presented in this paper based on relative virtual resistance for the two PWM rectifiers current sharing system. The output parallel-connected three PWM boost rectifiers are proposed in multiterminal dc grid to provide energy conversion. The simulation and experimental results show that the proposed method can achieve both good voltage regulation and good load sharing.
