Static Analysis of Vulnerability and Security Margin of the Power System

This paper introduces new concepts for evaluation of the power system steady state operations, namely the vulnerability index (VI) and margin index (MI). They provide quantitative vulnerability and security margin information about generation, transmission, load conditions and then the whole system....

Summary:This paper introduces new concepts for evaluation of the power system steady state operations, namely the vulnerability index (VI) and margin index (MI). They provide quantitative vulnerability and security margin information about generation, transmission, load conditions and then the whole system. System operators can assess the system security and vulnerability information using the margin and vulnerability indices. Therefore, they can take some preventive and emergency control steps to keep the system operating at the secure level
