| Abstract | |
The main objective of this work is to design a transient stability screening contingency program that is able to identify all critical contingencies in an electric power system using direct methods. The stability assessment is performed through several steps by mean of filters based on islanding detection, nonexistence of equilibrium points, PEBS, BCU and time-domain simulation of the power system. In each step of the analysis, all cases are classified as stable, unstable or uncertain cases by different criteria, resulting at the end of each step in a small number of possible critical contingencies. The proposed methodology was designed for reduced models of electric power systems, but all the techniques discussed in this work are also suitable for preserving structure models. (AU) | |
