Offshore Wind Power is boosting as one of the most attractive and effective ways to supply energy to our homes. The technology employed in this kind of renewable energy is still in expansion process and offers plenty of opportunities in the ambit of research to maximize its potential. The objectives of this project are to submerge into offshore wind power systems and to provide a bridge to cross to the professional ambit. With this aim the VSC-HVDC technology is explained and one of its most important components has been extendedly explained, the VSC. This device has been modeled and simulated by means of Matlab Simulink to obtain a realistic response. The reader also will find out the main advantages and requirements for a VSC and the control methodology employed to be achieved, as well as the tests realized to prove them.
