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),

Optimal placement of FACTS controllers for maximising system loadability by PSO [PDF]

, 2013
In this paper, a multi objective-based method has been suggested to enhance the power system loadability with optimal placement of flexible AC transmission system (FACTS) controllers using particle swarm optimisation (PSO) technique.

Probabilistic Voltage Stability Screening Under Stochastic Load Allocation at Weak Buses Using Stability Index

Energies
Voltage security assessment is increasingly challenged by stochastic demand growth and localized stress patterns that are not well represented by deterministic, single-snapshot analyses.

POWER SYSTEMS OPERATION IMPROVEMENT CONSIDERING LOSS MINIMIZATION AND VOLTAGE STABILITY ENHANCEMENT [PDF]

, 2021
The challenge of energy and power losses during electrical energy transmission from generation plants to users is a major problem that cannot be over-emphasized. These Losses are inevitable because they are inherent in the conduction of electrical energy

Stability analysis of power system under n-1 contingency condition [PDF]

Several voltage stability indices (VSIs) have been developed to assess the potential for voltage collapse. However, certain indexes are computationally costly. Meanwhile, some have been noted to underperform across various conditions.
