Comparison of voltage stability indexes considering dynamic load

2011 IEEE Electrical Power and Energy Conference, 2011
Eventhough voltage stability is a dynamic problem, static indexes are still important parameters in voltage stability analysis. Some important voltage stability indexes are reviewed and a comparison of their performance under dynamic load is given in this paper. The advantages and disadvantages of each index are demonstrated.

A voltage stability index for radial distribution networks

2007 42nd International Universities Power Engineering Conference, 2007
This paper presents a voltage stability index for identifying the most sensitive bus to the voltage collapse in the radial distribution networks. The developed index is based on the transferred active and reactive power of the distribution line. The performance of the index is tested on different loading conditions for different load models and ...

Development of a Versatile Voltage Stability Index Algorithm

2007 IEEE Canada Electrical Power Conference, 2007
Power 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 ...

Circuit analysis approach for determining voltage stability index

2015 IEEE 11th International Conference on Power Electronics and Drive Systems, 2015
Voltage Stability Index (VSI) is a commonly used performance indicator for electrical distribution networks. A high value of VSI at each node implies an overall stable distribution network. A variety of methods are available in literature to determine VSI of a distribution network connected in radial configuration. However, very little has been done to

Secondary voltage control of power grid using voltage stability index and voltage control areas

2017 North American Power Symposium (NAPS), 2017
This 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 ...

Performance evaluation of voltage stability index to assess steady state voltage collapse

2014 6th IEEE Power India International Conference (PIICON), 2014
The 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.

Application of Voltage Stability Index for Congestion Management

2016
Voltage 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.

Positive Sequence Based Catastrophe Theory Voltage Stability Index to Analyzed the Voltage Stability Index in the Unbalanced Radial Distribution Systems

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

Reactive Power Optimization Using Static Voltage Stability Index

Electric Power Components and Systems, 2001
This paper presents a new methodology for enhancement of voltage security using a voltage stability index. The objective function is the minimization of reactive power injection, which is of prime importance for maintaining desired level of voltage security. Linearized incremental model has been used.
