Abstract :
This paper proposed a new power exchanging control under unbalanced-fault conditions. This new control method has been implemented directly in three-phase (abc) reference frame without any additional reference transform and provides independent control of active /reactive power. Furthermore the synchronization is used based on EPLL, which can adopt frequency quickly. Therefore, transmission system operators (TSO) can correctly ride-through disturbances occur in the system.
