Data and Code for VELE-Based Structural Stress Analysis of IEEE Benchmark Power Grid Networks

This dataset contains the reproducibility materials for the manuscript entitled “Vertex Eccentricity Labeled Energy as a Structural Stress Indicator for Power Grid Resilience: A Study on IEEE Benchmark Networks.” The files include Python scripts, a Google Colab notebook, processed graph representations of IEEE30, IEEE57, IEEE118, and IEEE300 benchmark networks, node-attack trajectories, line-addition outputs, random-trial validation results, summary tables, figures, and run logs. The dataset supports the structural graph-based analysis reported in the manuscript, including the computation of Vertex Eccentricity Labeled Energy, bounded VELE resilience scores, comparison with standard graph measures, and evaluation under random, adaptive degree, and adaptive betweenness node attacks. The benchmark systems are treated as simple undirected graphs for structural screening only; no impedance, voltage, load, capacity, dispatch, or power-flow data are used in the reported experiments.
