Voltage stability analysis in transient and mid-term time scales
IEEE Transactions on Power Systems, 1996This paper reviews the general methodology of analysing voltage stability in the mid-term and in the transient time scale. It shows how a simplified simulation of the mid-term dynamics can only be combined with the analysis of "snapshots" using a linearised model for the transient dynamics.

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.

Review on Transient Voltage Stability of Power System
2020 IEEE Sustainable Power and Energy Conference (iSPEC), 2020In recent years, there have been frequent blackouts caused by voltage instability worldwide, causing huge economic losses. The highly centralized load center at the receiving end needs to feed a lot of energy from the remote power center in China, which makes the transmission capacity of the power grid closer to the transmission limit, and the ...

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 ...

Transient (Short-Term) Voltage Stability
2021The dynamic behavior of power system can be summarized and reflected by the nonlinear differential-difference-algebraic equations (DDAE). The differential equations partially reflect the dynamic behavior of dynamic elements in the power system, the difference equations partially reflect the discrete actions of system elements, and the algebraic ...
