In a world confronting with an increasing demand of power, the large offshore
wind power plants represent promising alternative sources of energy. Among the
available solutions, the VSC-based HVDC transmission systems represent at this
moment the most feasible and competitive solution for grid-integration of this large
offshore amount of power. Throughout this thesis the modeling and the control of
the VSC-based HVDC system are investigated and described. Two different control
methods capable of controlling such systems are proposed. Both developed control
strategies are implemented in the dq synchronous reference frame. In order to
analyze both steady state and dynamic behavior of the developed VSC-based HVDC
transmission system several study cases are carried out using MATLAB/Simulink.
Moreover, the results obtained from simulations are validated using a small-scale
laboratory setup (2.2 kW) controlled through a dSPACE platform.
