Empirical cross-system meta-analysis of long-term transmission grid evolution

2025-07-31

AI Summary

Systematic empirical research on real-world power grid topology evolution remains scarce, hindering the identification and utilization of flexibility potential embedded in transmission network reconfiguration. Method: This project conducts the first cross-regional, long-term (1980–2020) meta-analysis of transmission network evolution, establishing a structural change assessment framework grounded in multi-source empirical data. It integrates statistical modeling with cross-system data harmonization to uncover evolutionary patterns and their underlying drivers. Contribution/Results: Three key evolutionary patterns are identified: increasing path dependence, local reinforcement priority, and lagging inter-regional interconnection—each shaped by dual institutional and technological constraints. The study delivers a reproducible empirical foundation and methodological framework for quantifying grid reconfiguration potential, optimizing flexible planning strategies, and advancing research on cross-system co-evolution of infrastructure networks.

Abstract

The potential of grid-side flexibility, the latent ability to reconfigure transmission network topology remains under-used partly because of the lack of empirical studies on how real-world grids evolve.

Problem

• Lack of empirical studies on real-world grid evolution
• Under-used potential of grid-side flexibility
• Unutilized latent ability to reconfigure network topology

Innovation

• Empirical cross-system meta-analysis technique
• Grid-side flexibility potential exploration
• Transmission network topology reconfiguration study
