Abstract
Nowadays, wind energy is a promising alternative to the traditional energy sources. Due to the increasing wind power penetration, the improvements of the control strategies become a new challenge for the manufacturers in order to comply with the grid interconnection requirements. This project focuses on the control of the grid side converter which let the full controllability of the DC-link voltage and the reactive power delivered to the grid. Synchronous and stationary reference frame control strategies are implemented to control the power converter. Modeling and simulation of the grid side of the wind turbine system are performed. MATLAB/Simulink has been used to implement the models. Different tests have been done in order to analyze the control system. In addition, a small scale version of the system has been implemented for the laboratory. Two different control strategies are compared and the results are verified in the laboratory.
