A generative graph model for electrical infrastructure networks. (arXiv:1711.11098v1 [physics.soc-ph])
来源于:arXiv
We propose a generative graph model for electrical infrastructure networks
that accounts for heterogeneity in both node and edge type. To inform the
design of this model, we analyze the properties of power grid graphs derived
from the U.S. Eastern Interconnection, Texas Interconnection, and Poland
transmission system power grids. Across these datasets, we find subgraphs
induced by nodes of the same voltage level exhibit shared structural properties
atypical to small-world networks, including low local clustering, large
diameter and large average distance. On the other hand, we find subgraphs
induced by transformer edges linking nodes of different voltage types contain a
more limited structure, consisting mainly of small, disjoint star graphs. The
goal of our proposed model is to match both these inter and intra-network
properties by proceeding in two phases: we first generate subgraphs for each
voltage level and then generate transformer edges that connect these subgraphs.
