Abstract :
Unstable limit cycles (ULCs) provide a mechanism for nonlinear oscillatory phenomena in power systems. When ULC is located on the stability boundary, transient stability is determined by whether the post-fault initial condition is inside or outside the stable manifold of the ULC. Therefore, depending on its size, ULC can have a crippling effect on transient stability properties. In this paper, we present examples of ULCs in several power system models including a large system example
