Summary:Power system security assessment and enhancement are two major crucial issues in a large interconnected power system. System security can be classified on the basis of major functions that are carried out in control centers, namely system monitoring, contingency analysis and security enhancement. The key element involved in security assessment is contingency analysis. In real-time, all contingencies may not cause same severity level. To eliminate non-violation cases and select only critical cases, called contingency analysis, the idea of severity/performance indices seems to fulfill this need. Security enhancement incorporates security constrained optimal power flow (SCOPF) which ensures that system is operating at normal state by taking preventive and corrective control actions so that no contingencies result in violations. SCOPF recommends controller actions to optimize specific objective function such as fuel cost, power losses, emission that subject to a set of power system operating constraints. This paper presents a literature review on two topics which are reviewed in chronological order of appearance; security assessment and enhancement. We explore both traditional and soft computing techniques for assessing system security and enhancement of the power system and also identify key areas for future research.
