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.

Long term voltage stability thevenin index using voltage locus method

2014 IEEE PES General Meeting | Conference & Exposition, 2014
Monitoring long term voltage stability of the power grid is necessary to ensure the secure operation of the system. In this paper, the voltage locus of the load phasor as a function of the load increase is studied is studied from a geometric perspective.

A robust static voltage stability index for distribution networks

2010
In this paper, a new static voltage stability index is proposed for identifying the line or its corresponding bus on the verge of voltage collapse of distribution networks. The index is developed by using the distribution line receiving end bus voltage formulation, and its adequacy is evaluated on a modern distribution test system which has voltage ...
