Performance evaluation of static security analysis methods

This paper describes a method for static security analysis based on a coordinated combination of PI methods, subnetwork solutions, compensation methods and sparse vector methods. The method is hybrid utilizing PI methods and contingency screening/analysis methods. This paper focuses on the contingency screening/analysis method. It is capable of efficiently handling PV/PQ bus type conversions and islanding conditions caused by contingencies. It also features an “optimal” combination of computational procedures which yields the least execution time for a specified level of accuracy. The performance of the method is statistically evaluated on large power systems. The results clearly illustrate the superior performance of the method
