Abstract

This paper introduces a new approach of power system static security analysis based on the vulnerability index (VI) and network contribution factor (NCF) method. Vulnerability index method provides quantitative vulnerability information about generation, transmission, load condition, and the whole system. NCF method gives fast approximate power flow results due to parameter change (contingency) based on the base load flow condition and network information. The contingency list can be chosen based on NCF method and VI evaluation. Comparison with the full AC power flow method shows that this approach is promising for fast and accurate static security analysis
