ABSTRACT
Dynamic security characterizes a power-system's ability to withstand disturbances and ensure continuity of service. Unexpected behavior has been observed in many networks under unusual stress, behavior suggesting that some important system dynamics are not yet well understood and hence are not accounted for in simulations conducted for control and security purposes. Chaos theory, the study of nonlinear dynamics, may provide new approaches for understanding the transient behavior of complex power systems and for ensuring network stability. A three-bus model was enhanced to include generator dynamics, revealing several additional bifurcations, some of which lead to chaotic oscillation through period-doubling cascades. A complete characterization of structural stability for two-dimensional systems can be related to the nature of the equilibria and limit circles. Research has revealed that for systems characterized by more than two parameters, no complete description of structural stability is possible. The topic of artificial intelligence (AI) has gained the interest of researchers and scientists in many fields.
