A Review of Voltage Stability Assessment Techniques with an Improved Voltage Stability Indicator
International Journal of Emerging Electric Power Systems, 2015Abstract A blackout can take place in entire power system or a part of the system due to extreme voltage instability (voltage collapse) that can appear abruptly. Instability prediction and continuous monitoring of the power system performance is, therefore, known exigent.

Voltage stability assessment: Voltage control inadequacy problem
2018 Simposio Brasileiro de Sistemas Eletricos (SBSE), 2018The problem of voltage control inadequacy in voltage control devices in a power system is revealed, when an inverse relationship between controlling and controlled variables exists. The voltage control inverse relationship could adversely affect the voltage profile in a power system, thus, it is necessary to determine the relationship between ...

Inadequate voltage control in the assessment of voltage stability conditions
2015 CHILEAN Conference on Electrical, Electronics Engineering, Information and Communication Technologies (CHILECON), 2015Inadequate voltage control occurs when the controlling variable and controlled voltage of a control device are inversely related (i.e., not related in the usual way), potentially adversely affecting the system voltage level. This special situation can be identified by analyzing the elements of a sensitivity matrix constructed to show the relationship ...

VOLTAGE STABILITY ASSESSMENT AND ENHANCEMENT OF THE THAILAND POWER SYSTEM
IFAC Proceedings Volumes, 2006This paper presents voltage stability study of the Thailand power system by considering the existing Static Var Compensators, generation and load directions. An approach to determine appropriate voltage settings of existing Static Var Compensators is proposed in order to maximize static voltage stability margin of the system.

Properties of indices for voltage stability assessment
2013 8TH INTERNATIONAL SYMPOSIUM ON ADVANCED TOPICS IN ELECTRICAL ENGINEERING (ATEE), 2013The paper deals with evaluation of a power system from the view-point of voltage stability. It is concerned with the indices which are proposed as voltage collapse proximity indicators. In the existing papers, many such indices can be found. In the paper, the so-called line stability indices, defined using the static approach to the study of voltage ...

A New Line Voltage Stability Index (NLVSI) For Voltage Stability Assessment
2019Power system is probably one of the most complex dynamical systems. In these systems, active and reactive power demand is increasing day by day, other way it can be said that the stress on these systems is increasing. Under these stressed conditions, they are operating at the stability limits to meet their load demand.

Voltage Stability Assessment Using Line Stability Indices
2018 3rd International Conference and Workshops on Recent Advances and Innovations in Engineering (ICRAIE), 2018At present, after examining the stability of the voltage we found concerns in the regular working of the power systems. It was observed that there was a lot of load in the system which lead to the concerns. It is important to run the system with minimum power loss because of increasing need of power by the humans and lack of enough power sources to ...

Line indices for voltage stability assessment
2009 IEEE Bucharest PowerTech, 2009Voltage stability has become one of the most important issues in electrical power systems. The power system ability to maintain acceptable bus voltage is a very important characteristic of a network. This paper analyzes the performance of line stability indices.

Use of Voltage Stability Assessment and Transient Stability Assessment Tools at PJM Interconnection
2021Over the past few decades, PJM has moved voltage, transient, and dynamic stability analysis—historically the domain of planners and back-office engineers—into the control room. PJM utilizes the Real-Time Transfer Limit Calculator (RTTLC) to perform voltage stability analysis and determine operation limits.

An alternative method for voltage stability assessment in power system
2017 IEEE AFRICON, 2017Voltage stability assessment in power system has recently been a growing concern to power system utilities due to blackout experienced in a couple of years in some developed and underdeveloped nations. This paper presents an alternative method which is based on the topology of the power network to identify weak load buses that are susceptible to ...
