Probability of failure of overloaded lines in cascading failures
International Journal of Electrical Power and Energy Systems, 2015 Power grids are vulnerable to cascading failures, as shown by previous blackouts or major system disturbances. Line outages due to overload are often the main contributors to the cascading failures leading to these undesired situations. Indeed, the more a line is overloaded, the larger is its sagging, and hence the probability that it will be tripped ...

Cascading failures in complex networks [PDF]
Journal of Complex Networks, 2020 Abstract Cascading failure is a potentially devastating process that spreads on real-world complex networks and can impact the integrity of wide-ranging infrastructures, natural systems and societal cohesiveness. One of the essential features that create complex network vulnerability to failure propagation is the dependency among their ...

A Non-Scheduled Multi-Stage Decision-Making Approach to Control Cascading Failures
Frontiers in Energy Research, 2022 The control research on cascading failures is critical to ensure the reliability of power supply. A path-driven multi-stage corrective control model for the whole process of cascading failures is established to eliminate the risk of cascading failure ...

A review on simulation models of cascading failures in power systems
iEnergy, 2023 Among various power system disturbances, cascading failures are considered the most serious and extreme threats to grid operations, potentially leading to significant stability issues or even widespread power blackouts.

Cyber Attacks on Power Grids: Causes and Propagation of Cascading Failures
IEEE Access, 2023 Cascading effects in the power grid involve an uncontrolled, successive failure of elements. The root cause of such failures is the combined occurrence of multiple, statistically rare events that may result in a blackout.

Cascading failures in ac electricity grids [PDF]
Physical Review E, 2016 Sudden failure of a single transmission element in a power grid can induce a domino effect of cascading failures, which can lead to the isolation of a large number of consumers or even to the failure of the entire grid. Here we present results of the simulation of cascading failures in power grids, using an alternating current (AC) model.

AN URN MODEL FOR CASCADING FAILURES ON A LATTICE [PDF]
Probability in the Engineering and Informational Sciences, 2012 A cascading failure is a failure in a system of interconnected parts, in which the breakdown of one element can lead to the subsequent collapse of the others. The aim of this paper is to introduce a simple combinatorial model for the study of cascading failures.
