This paper presents a performance study of voltage source converter high-voltage direct-current (VSC-HVDC) transmission system for supporting grid voltage under different operating conditions. The VSC-HVDC transmission system is used to integrate an off-shore wind power plant to grid. The vector control method is used to make a decoupled control of active and reactive powers for grid voltage disturbances mitigation. The dynamic behavior of the system is evaluated using MATLAB/SIMULINK package. Finally, the control method of the system integration into a small-scale grid side converter connected to a virtual-grid using the TMS320F28335 from Texas Instruments has been implemented. The simulation and experimental results were matched showing a good performance under different operating conditions.
