The wind is the driving force for wind turbine,and it directly determines the dynamic characteristics of generator. Due to its randomness and intermittence, wind energy has great effect on the quality and
security of operation of power system. The main emphasis of this paper is to study the effect of wind speed fluctuation on the doubly fed induction generator connected to power system. Firstly, the mathematical models of a 3.6MW doubly fed induction generator and different wind patterns are
derived. The MATLAB/Simulink software is then
used to model the wind, wind turbine, doubly fed induction generator, and its controllers. Simulation results obtained from the model are used to analyze the effects of different wind speed fluctuation on system dynamic responses.
