Fast prediction of voltage stability index based on radial basis function neural network: Iraqi super grid network, 400-kV [PDF]

, 2011
With the increase in power demand and limited power sources has caused the system to operate at its maximum capacity. Therefore, the ability of determine voltage stability before voltage collapse has received a great attention due to the complexity of ...

Power system voltage collapse prediction using a new line stability index (NLSI-1): A case study of the 330-kV nigerian national grid

, 2019
The cumulative number of historical and recent power system outages substantiates the fact that further studies are necessary for an improved solution to the issue of voltage instability on the grid and the subsequent system collapse. Voltage collapse is

Composite Fractal Index for Assessing Voltage Resilience in RES-Dominated Smart Distribution Networks

Fractal and Fractional
This work presents a lightweight and interpretable framework for the early warning of voltage stability degradation in distribution networks, based on fractal and spectral features from flow measurements. We propose a Fast Voltage Stability Index (FVSI),

Voltage stability index for under voltage load sheeding scheme

, 2010
Power system is a nonlinear system that operates in a constantly changing environment. When subjected to a disturbance, the stability of the system depends on the initial operating condition as well as the nature of the disturbance.
