Abstract
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.
