Nonlinear dynamic load models with recovery for voltage stability studies
TLDR
In this article, a simple dynamic load model is proposed which captures the usual nonlinear steady-state behavior plus load recovery and overshoot, and a simple but important dynamic voltage stability analysis is developed based on the model.Abstract:
Motivated by projects in Sweden on voltage stability analysis and associated load modeling, a simple dynamic load model is proposed which captures the usual nonlinear steady-state behavior plus load recovery and overshoot. The parameters of the model can be related to physical devices depending on the time zone following a disturbance. A simple but important dynamic voltage stability analysis is developed based on the model. >read more

Towards a theory of voltage collapse in electric power systems
Ian Dobson,Hsiao-Dong Chiang +1 more
TL;DR: In this paper, the authors described the loss of stability when a stable equilibrium point disappears in a saddle node bifurcation and presented a simple model of the system dynamics after the bifurecation.

Load Representation in Power System Stability Studies
C. Concordia,S. Ihara +1 more
TL;DR: In this paper, the authors present a load model for power system stability studies, which is qualitatively different from generator load modeling in many aspects, such as reliability of load estimates, models of different components must be combined to obtain a reasonably manageable overall system model and field measurements are not at all easy.

Cascaded voltage collapse
Y. Sekine,H. Ohtsuki +1 more
TL;DR: In this paper, the authors analyzed the dynamic phenomena of power system voltage collapse by the method of dynamic simulation using induction motor models and concluded that the voltage can be recovered even after the node voltage is lowered beyond its static critical value.
