Probability of failure of overloaded lines in cascading failures
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 ...

Network topology and recovery delay thresholds determine cascading failure vulnerability in sports systems [PDF]
Network topology fundamentally determines how cascading failures propagate through sports systems, yet the risk thresholds governing this relationship remain unquantified.

A Non-Scheduled Multi-Stage Decision-Making Approach to Control Cascading Failures
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
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.

A method of identification of a vulnerable branch considering the propagation characteristics of cascading failures is proposed. To determine vulnerable components that trigger or expand the propagation of cascading failures, a fault chain model of a ...

A method for variance-based sensitivity analysis of cascading failures [PDF]
Cascading failures of relay operations in power systems are inherently linked with the propagation of wide-area power system blackouts. In this paper, we consider a power system cascading failure as an indicator matrix encoding: what power system relays ...

Cyber Attacks on Power Grids: Causes and Propagation of Cascading Failures
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.

A risk‐based multi‐step corrective control method for mitigation of cascading failures
Minimizing the risk of cascading failures in a power system is vital to balance the operational economy and security. A multi‐step corrective control (MSCC) method is proposed to mitigate cascading effects in terms of reducing risk of blackout by ...

Cascading failures in ac electricity grids [PDF]
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.
