Attack Identification and Correction for PMU GPS Spoofing in Unbalanced Distribution Systems [PDF]

IEEE Transactions on Smart Grid, 2020
Due to the vulnerability of civilian global positioning system (GPS) signals, the accuracy of phasor measurement units (PMUs) can be greatly compromised by GPS spoofing attacks (GSAs), which introduce phase shifts into true phase angle measurements ...

Tri-Objective Optimal PMU Placement Including Accurate State Estimation: The Case of Distribution Systems

IEEE Access, 2021
This paper presents a tri-objective Optimal Phasor Measurement Units (PMUs) Placement (OPP) strategy that is focused on the minimization of i) the total number of PMU channels, ii) the maximum state estimation uncertainty based only on high-rate PMU data

Graph-Based Faulted Line Identification Using Micro-PMU Data in Distribution Systems [PDF]

IEEE Transactions on Smart Grid, 2020
Motivated by increasing penetration of distributed generators (DGs) and fast development of micro-phasor measurement units ( ${\mu }$ PMUs), this paper proposes a novel graph-based faulted line identification algorithm using a limited number of ${\mu }$

A MATLAB-based PMU simulator

2013 IEEE Power & Energy Society General Meeting, 2013
The use of Phasor Measurement Unit (PMU) data in power system operation is of increasing importance. These data are currently used for real-time operation monitoring and off-line analysis. A good understanding of the phasor measurement process is essential for phasor quality analysis as well as for the design of advanced control and protection schemes.

Problematic media use is associated with poor oral health in Turkish school-age children: a pilot cross-sectional study

BMC Oral Health, 2023
Objectives In the recent years, problematic media use (PMU) has become a serious health concern for children. The precisely defined effects of PMU on children’s oral health are unknown.

Investigating Habituation to Premonitory Urges in Behavior Therapy for Tic Disorders [PDF]

, 2017
Behavior therapy is effective for Persistent Tic Disorders (PTDs), but behavioral processes facilitating tic reduction are not well understood. One process, habituation, is thought to create tic reduction through decreases in premonitory urge severity ...

Mathematical Models for the Single-Channel and Multi-Channel PMU Allocation Problem and Their Solution Algorithms

Algorithms
Phasor measurement units (PMUs) are deployed at power grid nodes around the transmission grid, determining precise power system monitoring conditions. In real life, it is not realistic to place a PMU at every power grid node; thus, the lowest PMU number ...
