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 ...

TENCON 2015 - 2015 IEEE Region 10 Conference, 2015
This paper presents a method based on V-Q sensitivity and modal analysis to study the transient voltage stability of receiving AC network with HVDC feeding. When faults of receiving network occur, HVDC recovery characteristics are analyzed, which have an important effect on voltage stability of receiving network.

Transient voltage stability signature in time domain simulations
Proceedings of 8th Mediterranean Electrotechnical Conference on Industrial Applications in Power Systems, Computer Science and Telecommunications (MELECON 96), 2002Real-time dynamic security assessment is an important function to be implemented in energy management systems. In order to apply the most proper corrective actions it is necessary, in real time simulations, to distinguish a transient instability from voltage instability.

Novel transient stability assessment using post-disturbance voltage fluctuations
2020 International Conference on Smart Grids and Energy Systems (SGES), 2020Transient stability assessment generally relies on angle-based approaches, which predict out-of-step often too late to maintain power system stability, and need commonly generator's rotor angles measured with a specially deployed optical or magnetic sensor.

Transient voltage stability enhancement using Static Synchronous Compensator
2014 International Conference on Advances in Electrical Engineering (ICAEE), 2014This Paper analyzes the application of Static Synchronous Compensator (STATCOM) to prevent the transient voltage instability of power systems due to the presence of large induction motor loads at the terminals of long transmission lines. The analysis is supported by transient time simulations for the complete power system following large disturbances ...
