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 ...

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 ...

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.

Secondary voltage control of power grid using voltage stability index and voltage control areas
2017 North American Power Symposium (NAPS), 2017This paper presents secondary voltage control of power grid using identification of voltage stability index and voltage control areas. Unlike, the traditional secondary voltage control in North America performed directly by switching capacitor banks and other reactive power sources, in the proposed approach generators are chosen first to perform ...

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

Performance evaluation of voltage stability index to assess steady state voltage collapse
2014 6th IEEE Power India International Conference (PIICON), 2014The paper presents performance analysis of a comprehensive index to foresee voltage collapse at the weak load buses in the power system. A different approach for the assessment of voltage stability margins based on the P-Q-V curve technique and Thevenin's equivalent is proposed.
