In this paper voltage source converter based HVDC (VSC-HVDC) is used for power transmission in asynchrony distribution systems. Direct power control (DPC) of three-phase space vector modulation (SVM) is employed for this control scheme. It is economically motivated to replace the AC line voltage sensors with a virtual flux (VF) estimator. The control system is resistant to the majority of line voltage disturbances using by the idea of virtual flux. It is also effective to damp system oscillations and enhance power quality when power flow is reversed. Superior advantages of this method are good dynamic response and unity power factor of rectifier.
