Increased bulk power transaction in competitive energy market together with large scale integration of energy resources. Control methodsfor grid-connected parameters are proposed here. The method could be generally applied for all grid-connected Parameter but may be of most importance in high-voltage dc (HVDC) applications. Different from the other control methods, the proposed method utilizes the internal synchronization mechanism in ac systems, in principle, similar to the operation of a synchronous machine. By using this type of power-synchronization control, the VSC avoids the instability caused by a standard phase-locked loop in a weak ac-system connection. Moreover, a VSC terminal can give the weak ac system strong voltage support, just like a normal synchronous machine does. The control method is verified by both  analytical models and time simulations.
