Abstract
This paper describes two algorithms for determining the value of a given system parameter that causes the crossing of a complex-conjugate eigenvalue pair through the small-signal stability boundary (Hopf bifurcation). A large-scale test system was utilized to validate the two proposed Hopf bifurcation algorithms. The results presented demonstrate the computational efficiency and numerical robustness of the algorithms.
