Searching for small-world and scale-free behaviour in long-term historical data of a real-world power grid

TL;DR

This study analyzes 70 years of Hungarian power grid data to identify small-world and scale-free network properties, providing insights into the grid's long-term structural characteristics.

Contribution

First evaluation of small-world and scale-free properties in long-term real-world power grid data using complex network analysis.

Findings

Identification of small-world properties in the power grid

Detection of scale-free degree distribution over time

Insights into the grid's evolving network structure

Abstract

In this paper the authors use the 70-year-long historical dataset of the Hungarian power grid to perform complex network analysis, which is the first attempt to evaluate small-world and scale-free properties on long-term real-world data.
