The evolution of the topology of high-voltage electricity networks

摘要: The electricity network represents an example of evolving complex system. first local networks contained only a few nodes, but within several decades, they have evolved into highly connected continental growth these was influenced by various factors such as economic, demographic, political and technological developments. In this paper, we analyse the French 400 kV transmission from its establishment in 1960 until year 2000. We study different topological characteristics that describe intensity process, number lines, average node connectivity overall length wires. compare results with economic demographic indicators order to identify which correlate rate network. Apart this, evaluate how efficiency vulnerability measures (clustering coefficient, information centrality, betweenness centrality) evolve course time. decisions regarding power grid topology are many, very often contradictory factors, costs, size covered area, demand, fault tolerance, reliability quality service. Our yield deeper insight process Critical Infrastructure (CI) construction.
