Abstract :
This paper deals with the impact of increased wind power generation on the behavior of the interconnected system during and after a contingency situation. The issues considered are the post-fault damping behavior of electromechanical oscillations, performance during a severe short-circuit and frequency stability after a sudden loss of generation. First, the doubly-fed induction (DFIM) based wind turbine and a conventional synchronous generator were simulated in a standalone mode to demonstrate the fundamental differences in terms of their damping behavior. The model was then extended to investigate the characteristic behavior of the DFIM during a severe fault to assess the limits of its fault ride-through capability. Finally, using a large interconnected system the effect of increased wind power generation on the frequency stability of the system after a loss of generation has been discussed.
