Abstract

This paper comprehensively reviewed the contingency analysis and its relation to blackouts. It explored the causes and impacts of blackouts in interconnected power systems, emphasizing the need for effective contingency planning and analysis to mitigate their occurrence and minimize their effects. The study critically examined existed literature, research studies, and practical approaches related to contingency analysis in the context of blackouts. By synthesizing and analyzing these sources, Contingency analysis is a crucial feature in modern Energy management system(EMS), ensuring static security in power systems by analyzing overloads and voltages outside allowed limits. Contingency analysis (CAs) with corrective action schemes struggle to differentiate safe operating regimes from hazardous ones, posing significant power system risks. The power system operator must always be aware of the system's status. The paper provided a holistic consideration of the subject matter. Additionally, it highlights key findings, emerging trends, and future directions for research and practical implementation in contingency analysis and blackout management.
