|Abstract: ||A new integrated mathematical model for the
simulation of offshore wind energy conversion system performance is presented in this paper. The mathematical model considers an offshore variable-speed turbine in deep water equipped with a permanent magnet synchronous generator using full-power two-level converter, converting the energy of a variable frequency source in injected energy into the electric
network with constant frequency, through a high voltage DC transmission submarine cable. The mathematical model for the drive train is a concentrate two mass model which incorporates the dynamic for the structure and tower due to the need to emulate the effects of the moving surface. Controller strategy
considered is a proportional integral one. Also, pulse width modulation using space vector modulation supplemented with
sliding mode is used for trigger the transistor of the converter.
Finally, a case study is presented to access the system
