A NEW VOLTAGE STABILITY INDEX FOR PREDICTING VOLTAGE COLLAPSE IN ELECTRICAL POWER SYSTEM NETWORKS [PDF]

open access: yes, 2017
Power system voltage instability often results in voltage collapse and/or system blackout which is a source of concern for power network operators and consumers. This work proposes a new line stability index that is suitable for investigating the voltage

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

open access: yesFractal 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),
