Accurate Assessment of Decoupled OLTC Transformers to Optimize the Operation of Low-Voltage Networks [PDF]
, 2019 Voltage control in active distribution networks must adapt to the unbalanced nature of most of these systems, and this requirement becomes even more apparent at low voltage levels. The use of transformers with on-load tap changers is gaining popularity,

IET Smart Grid, Volume 9, Issue 1, January/December 2026.This paper investigates load‐side resonance attacks on power grids via hyper‐scale data center load modulation, using Deep Reinforcement Learning to discover mode‐matched forcing patterns from local frequency observations alone. Multi‐agent coordination via Centralised‐Training‐Decentralised‐Execution enables distributed attackers to synchronize ...

Co-Simulation of Electromagnetic Transients and Phasor Models: A Relaxation Approach [PDF]
, 2016 Co-simulation opens new opportunities to combine mature electromagnetic transients (EMT) and phasor-mode (PM) solvers, and takes advantage of their respective high accuracy and execution speed. In this paper, a relaxation approach is presented, iterating

Physiological Reports, Volume 14, Issue 2, January 2026.Abstract Mathematical models are essential for understanding oxygen transport and utilization during metabolic transitions. An electrical analogy concept proposed that exponential PO2 transients arise from interaction between oxygen storage capacitance and transport conductances, but lacked explicit circuit representation limiting quantitative ...
