Failure and fault classification for smart grids
Energy Informatics, 2022 AbstractSmart grid (SG) has been designed as a response to the limitations of traditional power grids caused by growing power supply demands. SG is considered a critical infrastructure in which dependability plays a crucial role and manifestation of failures can lead to severe consequences.

A MISO FAULT DETECTION FOR HVDC GRIDS
IET Conference Proceedings, 2021 Research on fault detection for high-voltage direct current (HVDC) grids has had a focus on single-ended DC fault detection using information from only the local line end. This paper proposes the use of additional information from neighbouring lines around the same busbar in a multiple-input single-output (MISO) fault detection.

Largest Component and Node Fault Tolerance for Grids [PDF]
The Electronic Journal of Combinatorics, 2021 A graph $G$ is called $t$-node fault tolerant with respect to $H$ if $G$ still contains a subgraph isomorphic to $H$ after removing any $t$ of its vertices. The least value of $|E(G)|-|E(H)|$ among all such graphs $G$ is denoted by $\Delta(t,H)$. We study fault tolerance with respect to some natural architectures of a computer network, i.e.

Autonomous Smart Grid Fault Detection
IEEE Communications Standards Magazine, 2023 Smart grid plays a crucial role for the smart society and the upcoming carbon neutral society. Achieving autonomous smart grid fault detection is critical for smart grid system state awareness, maintenance and operation. This paper focuses on fault monitoring in smart grid and discusses the inherent technical challenges and solutions. In particular, we

Journal of Modern Power Systems and Clean Energy, 2023 The fault current level analysis is important for bipolar direct current (DC) grids, which determines the operation and protection requirements. The DC grid topology significantly impacts the current path and then the fault current level of the grid ...

Fault detection in dielectric grid scatterers
Optics Express, 2015 The problem of diagnosing a grid of small (in terms of the probing wavelength) dielectric scatterers is considered. The aim is to detect and locate possible defects occurring within a known grid when one (or more) scatterer is removed/missing (fault).

Fault Detection and Prediction in Smart Grids [PDF]
2018 IEEE 9th International Workshop on Applied Measurements for Power Systems (AMPS), 2018 Modern society is to a larger and larger extent dependant on electric energy, and hence the reliance on and utilization of the electric grid is increasing steadily. At the same time the production and consumption patterns are changing from large centralized generation of electric power and pure consumers to distributed generation (DG) and more complex ...
