A generative graph model for electrical infrastructure networks
2018
Journal of Complex Networks
Preserved Fulltext
Other Versions
We propose a generative graph model for electrical infrastructure networks that accounts for heterogeneity in both node and edge type. ...
We also include graph visualization comparisons, a brief analysis of edge-deletion resiliency, and guidelines for artificially generating the model inputs in the absence of real data. ...
Ultimately, our model may be used to generate synthetic graph data, test hypotheses and algorithms at different scales, and serve as a baseline model on top of which further electrical network properties ...
