Cascaded Voltage Collapse

IEEE Transactions on Power Systems, 1990
The dynamic phenomena of power system voltage collapse are analyzed by the method of dynamic simulation using induction motor models. From the viewpoint of dynamic phenomena, the voltage collapse starts locally at the weakest node and spreads out to the other weak nodes. The main conclusions drawn from this study are as follows.

Dynamic Mechanisms of Voltage Collapse

Systems and Control Letters, 1990
Abstract This paper presents the result of a thorough voltage stability analysis of a simple power system. Three mechanisms of dynamic voltage collapse are incorporated: generator excitation limit, load dynamics and on-load tap-changer. The effect of each individual mechanism is analyzed first and then the combined effects are used to reconstruct a ...

Dynamic Simulation of Voltage Collapse

IEEE Transactions on Power Systems, 1990
The problem of voltage collapse is approached by simulation of a power system using a slightly modified transient stability program. A sufficiently complex system with 39 buses and ten generators is used in the simulations. The system is stressed by progressively increasing the system load through a multiplier k.

Voltage Collapse Risk Assessment

Electric Power Systems Research, 2000
Abstract Several approaches have been proposed in the literature to analyze system voltage collapse, based on indices that can efficiently evaluate the load margin for which the system remains stable. All this discussion, including possible methods of solution, is being carried out under deterministic assumptions; load, generation and transmission ...

Discussion on Some Voltage Collapse Indices

Electric Power Systems Research, 2000
Abstract This paper discusses some voltage collapse indices with the help of bifurcation theory. Two main topics are presented: first, the identification of a well-behaved eigenvalue as a function of load increase; second a theoretical interpretation of the results. For this purpose, the center manifold theorem is employed.
