Evaluating System Cascading Failures

, 2017
This article shares methods used to evaluate system cascading failures. A cascading failure occurs when a problem is passed from one subsystem to a downstream subsystem creating a domino effect that undermines system efficiency and effectiveness. First,

Catastrophic cascade of failures in interdependent networks [PDF]

Nature, 2010
Many systems, ranging from engineering to medical to societal, can only be properly characterized by multiple interdependent networks whose normal functioning depends on one another. Failure of a fraction of nodes in one network may lead to a failure in another network. This in turn may cause further malfunction of additional nodes in the first network

Common cause failures and cascading failures in technical systems: Similarities, differences and barriers [PDF]

, 2018
Many technical systems continue to increase in size and complexity, with more interactions and interdependencies between components. Dependent failures, such as common cause failures and cascading failures, are becoming important concerns to system ...

Estimation for Expected Energy Not Served of Power Systems Using the Screening Methodology of Cascading Outages in South Korea

Energies, 2017
The uncertainty of complex power systems increases the possibility of large blackouts due to the expectations of physical events, such as equipment failures, protection failures, control actions failure, operator error, and cyber-attacks.

Towards Avoiding Cascading Failures in Transmission Expansion Planning of Modern Active Power Systems Using Hybrid Snake-Sine Cosine Optimization Algorithm

Mathematics, 2022
In this paper, a transmission expansion planning (TEP) model is proposed to guarantee the resilience of power systems and mitigate cascading failures’ impacts. The energy storage systems and fault current limiters’ planning models are integrated into the

Cloud-Network Disaster Recovery against Cascading Failures

, 2014
Cloud computing uses cloud networks (CNs) that integrate and virtualize computing servers and communication networks. In a CN, virtual machines (VMs) are interconnected through virtual networks (VNs) provisioned over a physical optical network.

Identifying the dominant operating variables to evaluate the cascading failure potential in the power system by theory of mutual information

International Journal of Electrical Power & Energy Systems
In this study, the potential of cascading failure as a result of transmission line outages through large power systems is evaluated. Transmission lines are more dispose of the outage resulting from different fault occurrences and extend the uncontrolled ...
