abstract = {Cascades of failures are among the biggest threats to
supply networks such as power grids: An initially failing
element may trigger the failure of other elements, thereby
eventually causing the entire network to collapse. Here, we
analyse the statistics of Line Outage Distribution Factors
(LODFs), which describe the rerouting of electric power
flows after a line failure. In particular, we demonstrate
that absolute LODFs are approximately log-normally
distributed throughout network topologies. We then
illustrate that this log-normal distribution of
redistribution factors results in a heavy tailed
distribution of outage sizes in a simplified, stochastic
cascade model over a certain range of parameters. This
cascade model extends previous stochastic cascade models by
adding more realistic redistribution mechanisms as well as
including more realistic initial trigger events. Our results
demonstrate that the statistics of redistribution factors is
a fundamental trait throughout different networks and
presents a possible explanation for the vast occurrence of
heavy tailed distributions in real-world reanalyses of power
outage sizes.},
