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),
