Evaluation of DFIG placement on small signal stability in multi-machine power systems

Abstract

Doubly fed induction generator (DFIG) behavior is different from synchronous generators. So, integration this generators with conventional synchronous generators, can make so many challenges for power systems. The most important challenge, can be doubly fed induction generator effect on dynamic and transient stability of power system. In this paper, small signal and transient stability analysis of a two-area power system is investigated that contains conventional synchronous generators and DFIG. Then the effect of DFIG placement in different buses is discussed. At first, small signal stability analysis without power system stabilizer (PSS) is carried, then synchronous generator equipped with PSS. Also, the best place in order to installation of DFIG in power system is determined and transient stability analysis has been done on it. To implementation of simulations, MATLAB software is used
