Analysis of a grid-connected wind energy conversion system based on complex simulation program

The present paper details a complex simulation program designed in MATLAB/SIMULINK aiming at the analysis of a complete grid-connected wind energy conversion system. The model contains the wind turbine, a permanent-magnet synchronous generator, a back-to-back electronic power converter, and the grid, as load for the electric energy production unit. Also, the maximum-power-point-tracking strategy is considered in the control of the generator, in order to extract the highest power possible from the wind turbine. The results of the simulation emphasize the behaviour of the simulation program, flexible enough to be used at any power level and any wind or turbine speed.
