“…The significance of the bifurcations theory in stability analysis was identified in the 1980's [14]; it is showed the presence of chaotic motions in the two-degree freedom swing equations. Subsequent applications of this theory have been directed to the following studies such as voltage collapse [15], sub synchronous resonance [16], Ferro resonance oscillations [17], chaotic oscillations [18], and design of nonlinear controllers [19]. Furthermore, this theory has been applied to assess the dynamical behavior of nonlinear components such as induction motors [20], load models [21,22], and tap changing transformers [23], power system stabilizers [24] and static VAR compensators [24,25].…”

This main aim of this study is investigation of the dynamic stability in a grid-connected wing turbine system based on Double Feed Induction Generator (DFIG) using the bifurcation theory. Regarding the overview of stability by Cardenas et. al. [1]. In our research, the proposed system model is simulated based on bifurcation theory in MATLAB software. In each step, one of the controlling or non-controlling parameters is selected. Eigenvalues of system are traced permanently during simulation. According to the change of the eigenvalues of system, due to the change of bifurcation parameter, stability of the equilibrium point and special bifurcations including saddle-node and Hopf bifurcations in the system are determined.
