A theoretical explanation of the basics of singular value decomposition (SVD) is given to justify their use in applications in power system dynamics and control. The minimum singular value of a matrix not only specifies the rank of the matrix, it als

A bifurcation analysis is used to investigate the complex dynamics of a heavily loaded turbine-generator system connected to an infinite busbar through a series capacitor-compensated transmission line. It reveals the existence of self-excited subsync

This paper reports on an application of the concept of the distance of a pair (A, B) to the nearest uncontrollable pair to the problem of placing a controller in a multimachine power system. The results given by Gahinet and Laub9 are adapted by allow

Bifurcations occurring in power system models exhibiting voltage collapse have been the subject of several recent studies. Although such models have been shown to admit a variety of bifurcation phenomena, the view that voltage collapse is triggered b

Dynamic bifurcations, including Hopf and period-doubling bifurcations, are found to occur in a power system dynamic model recently employed in voltage collapse studies. The occurrence of dynamic bifurcations is ascertained in a region of state and pa

Nonlinear phenomena, including bifurcations, chaos and crises, have been determined to be crucial factors in the inception of voltage collapse in power system models. The issue of controlling voltage collapse in the presence of these nonlinear phenom

The synchronizing torque matrices for a multimachine power system are analyzed. Two representations are used: the classical and a detailed one. It is shown that steady-state instability can be identified by checking the signs of the roots of the sync

Linear state feedback, under certain conditions, can interact with the ignored nonlinearities in a way that may result in unacceptable patterns of behavior of the closed-loop system. For example, the linear state feedback may create new equilibrium p

Formulates the equations of a two-machine infinite busbar system as two nonlinearly coupled oscillators. The authors derive conditions for the existence of two-to-one and three-to-one internal resonances. As a result of the analysis, two sets of four

The authors present arguments and results which show the importance of combined static/dynamic bifurcation analysis and of careful machine modeling in the study of voltage collapse. The value of modal coupling measures in this area is demonstrated. A
