Real-time simulation of a three-terminal high-voltage direct-current (HVDC) grid connected to a doubly-fed induction generator (DFIG) based wind farm has been presented in this paper. A recently invented control strategy, known as power-synchronization control, is applied for the integration of the wind farm to the HVDC grid. The dynamic performance study of the system under normal wind power fluctuations with wind speed and under some severe fault situations have been studied to demonstrate the effectiveness of the control strategy.
