Control and Simulation of Hybrid VSC-HVDC Transmission Systems for Offshore Wind Farm Applications
This paper presents the control systems of hybrid VSC-HVDC transmission systems is applied for offshore wind farm applications. The conventional voltage source converter (VSC) is applied for rectifier-side converter and modular multilevel converter (MMC) is applied for inverter-side converter. This topology is maintained the flexible control of active and reactive power and it can improve the voltage waveforms and harmonics of output power qualities. The simulation systems are simulated by MATLAB/Simulink program. The simulation results are shown performances of the control systems are proposed and output voltage waveforms and total harmonic distortion (THD) of the proposed system are improved the power quality without output filter required.
