Improvement of DFIG inertia response by using additional controlling parameters

Double-fed induction generators is introduced as the dominant generator in comparison with synchronous generators. With increased production capacity in wind farms their role in power system stability has become important. Inertia response is the first reaction of the generator to the frequency disturbance in power system. Synchronous generators have a high inertia response but DFIG has a very low inertia response, because its controller takes the slip of machine within fix range. In this paper the inertia response of doubly fed induction generator is improved by using additional parameters in control systems.
