To demonstrate the performance of the proposed method under disturbance conditions, the system was simulated with a floating wind speed and the results are presented for the DTC-SVPWM with two and three levels.
For a floating wind speed, the turbulence component is considered as a stationary random process and so does not dependent on the mean value of the wind speed. The floating wind speed fluctuates between 10 and 12
m/s. The simulation results are shown in Fig. 9.77
. The results show a clear improvement in the response of the DC-link voltage for the SVPWM with three-level topology and only few ripples can be seen in the transient responses of active and reactive powers ...
