Abstract

This paper deals with the application of an adaptive Implicitly Restarted Arnoldi Algorithm based on Krylov subspaces coupled with a dynamic switching approach to the small signal stability eigen analysis problem for power systems. The goal of the modified algorithm is to converge quickly and directly to the sought critical eigenvalues concerned with poor damping ratios directly from the algorithm calculation.
