Structural Properties and vulnerability of Iranian 400kv Power Transmission Grid: a Complex Systems Approach

Abstract

M.A.S. Monfared and Zohre Alipour

We investigate, for the first time, the structural properties of the very high voltage (400kv) power transmission network of Iran. Researches in complex systems theory have suggested that topology of the most real networks display power law shaped degree distribution, as a signature of complex networks. However, observations shed doubt on this as the degree distribution of power grids studied in different countries display exponential degree distribution rather than power law distribution (fat tailed shapes). We perform our analysis on Iran’s power grid to provide more evidence for this interesting and important result. In addition, we provide some analysis for assessing the vulnerability and reliability of the power grid.
