ABSTRACT
The increased level of penetration
of wind generators into modern power system has significant effect on network operation.
The time varying nature of wind speed has significant effect on performance of wind
generator, therefore efficient mechanism for stabilizing the output of the wind
generator is very much needed. Self-excited induction generators (SEIG) already
existing in the network are sensitive to wind speeds. In this paper, a new method
for voltage control of SEIG utilizing reactive power enhancing capabilities of doubly-fed
induction generator (DFIG) is simulated and its effect on the network is analyzed
for varying wind speeds. The choice of placing DFIG adjacent to SEIG or at another
bus is also addressed in this paper with simulation results. The results show that
this method of utilizing the reactive power capabilities of DFIG enhances voltage
stability of SEIG as well as system stability.
