![عکس صفحه اول مقاله: Local and global bifurcations in a small power system Local and global bifurcations in a small power system](/preview/png/399937.png)
This paper presents a number of local and one global (homoclinic loop) bifurcation observed in a small power system involving a load tap changer transformer and an induction motor. Besides the well-known generic local bifurcations (saddle-node and generic Hopf), the paper presents examples of higher codimension bifurcations, such as fold with double zero eigenvalues, degenerate Hopf, and swallowtail bifurcation.
► We investigate the conditions under which a small power system may experience bifurcations.
► Standard models of Load Tap Changer and Induction Motor are utilized.
► Bifurcations drastically affect stability properties of the system.
► The focus is set on state space analysis to examine the properties of the system at bifurcation points.
► Higher codimension bifurcations are investigated and theoretically verified.
