Voltage stability assessment in power systems using line voltage stability index

Computers and Electrical Engineering, 2018
Abstract The stressed operating conditions of transmission systems may lead to voltage collapse with consequent interruption in power supply. Therefore, it is necessary to continuously monitor the voltage stability of power system to avoid voltage collapse.

Technique for voltage stability assessment using newly developed line voltage stability index

Energy Conversion and Management, 2008
This paper presents an efficient technique for voltage stability assessment using a newly developed line voltage stability index that becomes half at a collapse point. Power flow equations have been used to identify critical lines, which may be vulnerable during an increased loading condition.

Local Voltage-Stability Index Using Tellegen's Theorem

IEEE Transactions on Power Systems, 2006
Summary form only given. In the paper, the Tellegen's theorem and adjoint networks are used to derive a new, local voltage-stability index. The new approach makes it possible to determine the Thevenin's parameters in a different way than adaptive curve-fitting techniques, from two consecutive phasor measurements.

A new node voltage stability index based on local voltage phasors

Electric Power Systems Research, 2009
The paper proposes an equivalent system model (ESM), which includes effects of both local network and system outside the local network. A new node voltage stability index called the equivalent node voltage collapse index (ENVCI), which is based on ESM and uses only local voltage phasors, is presented.

Optimal reactive power dispatch for improving voltage stability margin using a local voltage stability index

Energy Conversion and Management, 2012
Abstract Management of reactive power resources is vital for stable and secure operation of power systems in the view point of voltage stability. This paper deals with the management of on-load tap changers (OLTCs) and dynamic VAR sources (including synchronous generators, synchronous condensers, and shunt reactive power compensators) to improve ...

Voltage Stability Improvement Using Voltage Stability Index Optimization

2020 International Conference on Power, Energy and Innovations (ICPEI), 2020
Voltage stability improvement using line voltage stability index based on optimal power flow (OPF) in power systems is presented in this work. Line voltage stability index (LVSI) traditionally adopted to identify the most critical line in the system where its value is in the range of 0 (no load) and 1 (voltage collapse) has been applied as part of the ...

Voltage stability index for online voltage stability assessment

2015 North American Power Symposium (NAPS), 2015
This paper proposes a voltage stability index to predict voltage collapse in power system. The index is based on maximum loading capability of the bus combined with a thevenin equivalent method for the aggregated representation. The technique is applied to transmission test system. Using thevenin equivalent calculated by fast load flow or PMU data, the
