The physics of power systems operation [PDF]

open access: diamondEPJ Web of Conferences, 2015
The article explains the operation of power systems from the point of view of physics. Physicists imagine things, rather than in terms of impedances and circuits, in terms of fields and energy conversions. The account is concrete and simple.

A characteristic oriented probabilistic stability assessment method based on physics-informed neural network for stochastic power system

open access: goldInternational Journal of Electrical Power & Energy Systems
The significant stochasticity introduced by renewable energy and flexible loads challenges traditional deterministic stability methods in power system. To address the stability challenges posed by stochastic disturbances, by integrating physics-informed ...

Physically Flexible Ultralow-Power Wireless Sensor

open access: yesIEEE Transactions on Instrumentation and Measurement, 2022
The key challenges of local sensor networks are in supporting high sensor density, information security, physical size, and especially energy efficiency at a level that could eliminate the need for batteries or external power supplies. This article presents a novel scheme that answers all issues at the cost of minor information losses in low data rate ...

Design and Emulation of Physics-Centric Cyberattacks on an Electrical Power Transformer

open access: yesIEEE Access, 2022
Malware that attack the electrical power grid consist of exploits and operations modules. The exploits are similar to those of traditional malware. These malware hack into an industrial computer and subsequently deploy operational modules.

First results from a 760-GW linear transformer driver module for Z-pinch research

open access: yesMatter and Radiation at Extremes, 2021
In this paper, the results of tests on a 0.76-TW linear transformer driver (LTD) module for Z-pinch research are presented for the first time. Ten LTD cavities, each generating a 1-MA/90-kV pulse on a matched load, were connected in series with a ...

A switchable terahertz metamaterial absorber between ultra-broadband and dual bands

open access: yesFrontiers in Physics, 2023
Based on the phase change properties of vanadium dioxide (VO2), we propose a terahertz metamaterial absorber that can be switched flexibly between ultra-broadband and dual bands.

Analysis of the D-wave $$\Sigma $$ Σ -type charmed baryon states with the QCD sum rules

open access: yesEuropean Physical Journal C: Particles and Fields, 2023
We construct the $$\Sigma $$ Σ -type currents to investigate the D-wave charmed baryon states with the QCD sum rules systematically. The predicted masses $$M=3.35^{+0.13}_{-0.18}\,\textrm{GeV}$$ M = 3 .

What are the Problem Representations and Assumptions About Gender Underlying Research on Gender in Physics and Physics Education? A Systematic Literature Review

open access: yesRevista Brasileira de Pesquisa em Educação em Ciências, 2020
This work offers a systematic literature review of Brazilian and international research on gender in physics and physics education published over the last decade (2010–2019). We draw on a poststructuralist analytical approach to discuss assumptions about
