Abstract: Engineering systems are nowadays expanding beyond expected limits and their complexity is also increasing. One of the largest integrated system is power system. Some well-designed power system experience strange situation and suffer through chaos owing to weak dynamic performance. Stability issues also haunt power system in such cases. Loss of stability investigation in power system leads to evidence of chaos as intermediate state quite often. Black swan theory tells us to be ready for unseen unruly behavior at any time. Noah and Joseph effects are also surfacing in almost every large expanding power system from different parts of world. Complexity of system component behavior and complex stability boundaries pose a threat and ready to push power system where chaos is prevalent. It is debatable to see whether chaos leads to instability. This paper closely summarizes the chaos studies in light of reported research and advocates strongly the inclusion of advancement in chaos theory for detailed investigation post disturbance. This paper deals with a comprehensive review of strange behavior of nonlinear dynamic system and relevance of such studies for future anomalous behavior in the light of complexity science applied to engineering disasters such as blackouts. It is targeted to provide direction for futuristic complexity arising due to working on the brink of instability for economic reasons and to have certain preparation before inevitable blackouts, disasters and failures. A classified list of more than 50 relevant research publications is also given for quick reference.
Keywords: Lyapunov exponent (LE), single machine infinite bus (SMIB), dynamic stability assessment (DSA)
