초록
Hopf and saddle-node bifurcation have been recognized as some of the reasons for voltage stability problems in a variety of power system models. Local bifurcations are detected by monitoring the eigenvalues of the current operating point. Therefore, many papers have used the methods using the eigenvalues. However, this paper discusses the bifurcations without calculating the eigenvalues as the system parameters vary In the 3 node system. Instead of calculating the eigenvalues, we use directly the coefficients of characteristic equation of Jacobian matrix. Also, the coefficients are used as stability index.
