Hybrid transient stability analysis of power systems having large penetration of doubly fed induction generator based wind energy conversion system

Wind power has emerged as one of the most popular forms of renewable energy by virtue of its free availability. The larger proliferation of wind generators presents significant challenges to the stable operation of today’s power systems. Due to the advantages of Doubly-Fed Induction Generators (DFIG) over other wind generators, the majority of wind farms are using variable speed wind turbines equipped with DFIG. In this paper, the impacts of grid- connected large DFIG based wind farms on power system Transient Stability (TS) is studied. The well-known Western System Coordinated Council (WSCC) 3-machine, 9-bus system is used as the test system to carry out the said analysis. The test system - with DFIG based wind farm integrated into it, is modeled and analyzed in a simulation environment.
