Nowadays the modern power systems are large complex systems and widely distributed geographically. The increase in demand, generator reaching reactive power limits and line/generator outages may operate the power system in stressed conditions leads to voltage instability or voltage collapse. Voltage stability has become of major concern among the power

Voltage stability assessment using equivalent Thevenin
2015 IEEE Thirty Fifth Central American and Panama Convention (CONCAPAN XXXV), 2015The voltage stability in the power systems operation has taken importance due to the restrictions in the network when there is a growing demand. This has motivated hundreds of researchers to develop methods to detect the voltage instability's proximity, which reduces computational time and helps to take accurate decisions, guaranteeing a reliable and ...

Voltage stability assessment of a large power system
2008 IEEE Power and Energy Society General Meeting - Conversion and Delivery of Electrical Energy in the 21st Century, 2008Modal analysis and reactive power reserve method are applied in the Entergy electrical system to find the buses and zones prone to voltage instability. In the modal analysis method, weak zones are identified by monitoring the participation factor of the buses in the critical modes.

Voltage stability assessment of AC/DC systems
IEEE PES T&D 2010, 2010In this paper, a comprehensive and systematical analysis method is proposed to assess voltage stability of AC/DC systems. The traditional modal analysis method generally applied to AC systems will be extended to the application of AC/DC systems by introducing the eliminated variable AC/DC load flow. The dynamic components, such as excitation system, DC

Voltage Stability Assessment of the Salvadorian Power System
2006 IEEE PES Power Systems Conference and Exposition, 2006With the deregulation of the Salvadorian electricity system in 1998, some important changes have happened in its transmission grid. In 2003, a new interconnection with Honduras has created a regional electricity market in the Central America. In addition, there has been a significant growth in the Salvadorian load that increases the loading in the ...

Towards a neural network based voltage stability assessment
1994This paper presents a neural-network based method for evaluating on-line power system voltage stability. Starting with an appropriate linearized model of the system, the proximity of the power system to the voltage instability is quantified by using a suitable index.
