| Abstract | The high penetration of wind power generation into the grid evokes all the concerns for the deep understanding of its behavior and impact on the existing power system. This paper investigates the optimal operation of the Doubly Fed Induction Generator (DFIG) for the maximum power point tracking in deep with modal analysis. The grid connected DFIG system has been examined in two cases viz. open-loop case and closed-loop case where closed-loop case consists the system with the Flux Magnitude Angle Control (FMAC) and Direct Torque Control (DTC) approach. Various modes of the oscillation and their damping factor has been found in both the cases for the examination of the internal behavior of the system. Further, the effectiveness of the all the employed controls along with MPPT when the system is subjected to a stepped wind speed disturbance and voltage-dip have been confirmed. It was found from the simulation and the modal analysis that the frequency of the various oscillating modes is lesser while the damping is improved in the case of DTC control. |
