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 ...

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.

Global Transient Stability and Voltage Regulation for Power Systems
IEEE Power Engineering Review, 2001Summary form only given as follows. This paper is concerned with the global control of power systems. It arises from the practical concern that transient stability and voltage regulation are both important properties of power system control, but they are ascribed to different model descriptions and relate to different stages of system operation (i.e ...

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 ...

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 ...
