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 ...

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.

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 ...

The Effect of Branch Parameter Errors to Voltage Stability Indices
2016Errors in the values of network parameters stored in the control center may affect the important application of voltage stability monitoring. This paper investigates the effect of branch parameters errors to voltage stability monitoring, using the state vector obtained by the state estimator.

Neural-network representation of Voltage Stability Indices at the voltage collapse
2011 North American Power Symposium, 2011Representing system security in power flow based system models by the scalar magnitude of a Voltage Stability Index (VSI) may be a very difficult task, which may even render the applicability of such models impractical. VSIs at voltage collapse points are difficult to predict when reactive power generation limits are taken into account in system ...

2015 5th Nirma University International Conference on Engineering (NUiCONE), 2015
Voltage Stability and Voltage Security are considered as important concerns in power system planning and operation. To provide reliable, secure and stable electrical power to the customers, is the main task of power system engineer. To meet these requirements simultaneously, the power system is to be operated closer to its stability limits which cause ...

A Comparative analysis of line stability indices for dynamic voltage stability
2017 International Conference on Engineering Technology and Technopreneurship (ICE2T), 2017Modern power system networks are often subjected to high stress due to meet the growing energy demand and operated close to their maximum stability limits. As a result, these networks are becoming less secure and always expecting the risk of voltage instability.

Assessment of line stability indices in detection of voltage stability status
2017 IEEE International Conference on Environment and Electrical Engineering and 2017 IEEE Industrial and Commercial Power Systems Europe (EEEIC / I&CPS Europe), 2017During the last decade, several line indices have been proposed to assess voltage stability status of power systems based on transmission lines capability. In these methods, it is assumed that both the active and the reactive powers flow in the same direction from the sending bus to the receiving one. Then, the distance from existing operating point to

Performance Evaluation of Voltage Stability Indices for a Static Voltage Collapse Prediction
2020 IEEE PES/IAS PowerAfrica, 2020The frequent happenings of voltage collapse in a power system in the recent time as a result of continuous increase in power demand has been a concern and has posed a great threat to power system utilities. In this paper, to predict a voltage collapse bus, an approach named critical bus voltage stability index (CBVSI) which is based on the voltage ...

Analysis and Comparison of Line Voltage Stability Indices
2018 6th International Renewable and Sustainable Energy Conference (IRSEC), 2018Voltage stability indices are one of the powerful means of power system monitoring. With the existence of several ones in literature, some of them are less accurate and insensitive to some kinds of disturbances and especially when the power system operates near to its load ability limit.
