Power systems are the most complex systems and have great importance in modern life.
They have direct impacts on the modernization, economic, political and social aspects. To …

In the Internet of Things (IoT), various devices operate collaboratively in collecting data,
relaying information to one another, and processing information intelligently. Due to …

The modeling of cascading failure in power systems is difficult because of the many different
mechanisms involved; no single model captures all of these mechanisms. Understanding …

In a cascading power transmission outage, component outages propagate nonlocally; after
one component outages, the next failure may be very distant, both topologically and …

In this paper, the interactions between component failures are quantified and the interaction
matrix and interaction network are obtained. The quantified interactions can capture the …

A large amount of uncertainty introduced into power systems may affect the system
vulnerability to cascading failures. The objectives of this study are to analyze the power …

We use observed transmission line outage data to make a Markovian influence graph that
describes the probabilities of transitions between generations of cascading line outages …

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 …

In this paper, we compare the effects of failures in power grids under the nonlinear AC and
linearized DC power flow models. First, we numerically demonstrate that when there are no …

We show how to use standard transmission line outage historical data to obtain the network
topology in such a way that cascades of line outages can be easily located on the network …
