A Review of Overcurrent Protection in Smart Grids Under Cyber‐Physical Threats With a Cyber‐Physical Evaluation Framework

Energy Science &Engineering, EarlyView.
By manipulating current and voltage measurements, an assailant can induce unwanted relay action while attempting to avoid detection. Detecting advanced cyber intrusions in power protection environments requires specialised data analysis and anomaly detection methods.

Estimacija stanja u elektroenergetskom sistemu sa PMU uređajima i maliciozni napad injektiranjem loših merenja i njegova detekcija

Energija, Ekonomija, Ekologija
Ovaj rad istražuje značaj primene metode estimacije stanja u elektroenergetskim sistemima, posebno fokusirajući se na ulogu PMU (Phasor Measurement Unit) uređaja. Prikazane su osnovni principi i prednosti estimatora stanja u odsustvu PMU merenja, a zatim

A novel multi-task learning method for evaluating short-term voltage stability with incomplete PMU measurements

Complex & Intelligent Systems, 2023
Methods for short-term voltage stability (STVS) assessment based on phasor measurement unit (PMU) data have become quite abundant. However, most of them are challenged to deal with the commonly encountered incomplete PMU data.

PMU‐Based Wide Area Monitoring With Machine Learning to Prevent Blackouts in Bangladesh Power System

Energy Science &Engineering, EarlyView.
A Unified Real‐time Dynamic State Measurements (URTDSM) system with PMU and Phasor Data Concentrator (PDC) deployment plan has been proposed to avoid blackout in the Bangladeshi power system. Machine learning has been used to process data from PMU to identify abnormal events. ABSTRACT The electrical power system must be trustworthy and secure enough to

Targeting ligament boundaries rather than alignment boundaries in augmented‐reality‐assisted total knee arthroplasty ensures comparable gait patterns between operated and contralateral limbs

Knee Surgery, Sports Traumatology, Arthroscopy, EarlyView.
Abstract Purpose Modern personalised total knee arthroplasty (TKA) techniques aim to mimic natural knee kinematics by focusing on soft‐tissue dynamics rather than static alignment. However, a consistent definition of the optimal ligamentous balance has not yet been established.

Development of a reference Phasor Measurement Unit (PMU) for the monitoring and control of grid stability and quality [PDF]

EPJ Web of Conferences, 2014
This paper discusses the details of the development of a Phasor Measurement Unit regarding the requirements of the IEEE C37.118-2005 synchrophasor standard relative to steady-state conditions on grid monitoring and control. This phasor measurement unit is intended to be used for field tests sooner.

Nitrogen‐Doped GeTeS Ovonic Threshold Switching Selector With Optimized Performance Trade‐Off for 1S–1R Phase‐Change Memory

Small, EarlyView.
This study introduced a Ge‐Te‐S co‐sputtering process to resolve the performance trade‐off between GeTe and GeS in OTS selector devices, and improved device durability through nitrogen doping. Furthermore, in a 1S‐1R structure incorporating phase‐change memory devices, it simultaneously achieved excellent thermal stability, durability, high‐speed ...
