Detecting transient voltage stability and voltage sag
COMPEL - The international journal for computation and mathematics in electrical and electronic engineering, 2004This paper presents method to discriminate between transient voltage stability and voltage sag. The discrete wavelet transform (WT) is a powerful tool in the analysis of the transient phenomena in power systems because of its ability to extract information in both the time and frequency domain.

TCSC as a transient voltage stabilizing controller
2001 IEEE Power Engineering Society Winter Meeting. Conference Proceedings (Cat. No.01CH37194), 2002TCSC has been proposed to enhance the voltage stability by changing the reactive power distribution in the power system. The authors have discussed the effect of TCSC on steady state voltage stability and small-signal voltage stability. This paper discusses the TCSC's enhancement on transient voltage stability.

IEEE Power Engineering Society General Meeting, 2005, 2005
This paper presents a technique for accurate discrimination between transient voltage stability and voltage sag by combining damped sinusoids-based transient modeling with neural networks. Transient modeling is accomplished by energy adapted matching pursuits with an over-complete dictionary of damped sinusoids.

Transient Stability of Low Voltage Micro Grid
2019 International Conference on System Science and Engineering (ICSSE), 2019The micro grids (MG) is an essential part of smart grids, since distributed generations based on renewable energy sources are becoming incredibly popular. For low-voltage micro grid, this popularity becomes transparently obvious. In a low-voltage MG islanded mode operation, the type 4 wind turbine generators, connecting to grid through the inverter ...
