Development of a Versatile Voltage Stability Index Algorithm
2007 IEEE Canada Electrical Power Conference, 2007Power system experts have shown interest in the development of methods for predicting system status in the form of voltage stability indices. These indices performed well because they were primarily used for system planning as utilities then were either highly localized and regulated by the state or owned and operated by big electricity consumers ...

Effectiveness analysis of voltage stability margin index
POWERCON '98. 1998 International Conference on Power System Technology. Proceedings (Cat. No.98EX151), 2002The concept of the validity of the power system voltage stability margin index (VSMI) and its definition are presented. For a simple system, a comprehensive analysis for the validity of VSMI is given. For complex systems, the validity of VSMI is illustrated by examples. The linearity of VSMI is also evaluated.

On-line voltage stability based contingency ranking using fast voltage stability index (FVSI)
IEEE/PES Transmission and Distribution Conference and Exhibition, 2003Voltage instability is one phenomenon that could happen in a power system due to its stressed condition. The result would be the occurrence of voltage collapse which leads to total blackout to the whole system. Therefore voltage collapse prediction is important in power system planning and operation so that the occurrence of voltage collapse due to ...

A Linear Voltage Stability Index to Estimate the Distance to Voltage Collapse
Australian Journal of Electrical and Electronics Engineering, 2008AbstractThis paper proposes a new voltage stability index (VSI) that has a more or less linear characteristic, and thus can provide better estimation of the distance to voltage collapse. It requires only the normal power flow solution and the type-1 low voltage solution of the critical or weakest bus of the system. The effectiveness of the proposed VSI

Application of Voltage Stability Index for Congestion Management
2016Voltage stability is a relevant problem in power system as far as congestion management is concerned. Ranking is calculated using the line voltage stability index. All the system buses have been loaded one by one up-to maximum load-ability limit and maximum load-ability limit is based on voltage stability index.

Student Conference on Research and Development, 2003
Since a couple of decades ago, voltage stability assessment has received increasing attention due to the complexity of power systems. With the increase in power demand and limited power sources has caused the system to operate at its maximum capacity. Therefore, a study that is able to determine the maximum capacity limit before voltage collapse must ...

Effect of DERs on the Voltage Stability of Transmission Systems using a Voltage Stability Index
2021Interconnection of DERs into the transmission lines is starting to take a substantial share of the total power capacity. Although the largest share of power generation attributes to coal and gas power plants, renewable energy is gradually increasing.

A new node voltage stability index based on local voltage phasors
Electric Power Systems Research, 2009The 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.

International Review of Automatic Control (IREACO), 2016
This paper presents a new method to obtain a voltage stability index for unbalanced radial distribution system. Voltage stability index (VSI) is used only for balanced radial distribution system. By using the sequence component, the unbalanced in distribution system could be simplified into a single-phase system. From the positive and negative sequence

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 ...
