In power system operation, there are usually a few vulnerable lines (VLs) which are prone to
exacerbate the propagation of cascading failures and lead to severe blackouts with high …

The potential for cascading failure in power systems adds substantially to overall reliability
risk. Monte Carlo sampling can be used with a power system model to estimate this impact …

Identification of vulnerable lines in power systems has great meaning to predict cascading
failures and prevent the blackouts. A novel approach to identify the vulnerable lines in power …

The analysis of severe cascading blackouts is an essential issue in power grid planning and
operation. As there are a tremendous number of possible cascade paths in a large power …

How well can a typical electrical power system withstand a sophisticated malicious attack
undertaken against its exposed branches? This paper seeks to articulate a comprehensive …

Cascading blackouts typically occur when nearly simultaneous outages occur in k out of N
components in a power system, triggering subsequent failures that propagate through the …

Knowing the ability of networked infrastructure to maintain operability following a spatially
distributed hazard (eg an earthquake or a hurricane) is paramount to managing risk and …

Despite the infrequent occurrence of cascading power failures, their large sizes and
enormous social costs mean that they contribute substantially to the overall risk to society …

Electricity is a critical component in our daily life. Because it is almost always available, we
take it for granted. However, given the proper conditions, blackouts do happen every once in …

This paper proposes a novel algorithm based on the identification of the most influential
lines to speed up the simulation of severe cascading failures in power systems. To this end …
