Digital Twin for SWER Network Communication Channel
US & West ·
To upgrade Single-Wire Earth Return (SWER) networks for smart grid capabilities, Narrowband Power Line Communication (NB-PLC) is proposed. A digital twin of an operational SWER network up to 300 kHz was developed, integrating a segment-by-segment line model with Vector Network Analyzer measurements of physical hardware, replacing uniform assumptions with empirical component responses to characterise the channel more accurately.
Why it matters
A communication channel digital twin helps model and manage energy grid infrastructure during digitalisation.
Channel Modeling of Single Wire Earth Return Networks for Narrowband Power Line Communication and Sensing: A Field-Validated High-Frequency Digital Twin
A concept for a digital twin of a mouse is proposed as an embodied dynamical system unifying neural activity, biomechanics, sensory feedback, and environmental interactions. Construction relies on CT, anatomical sections, and Scx-GFP imaging, along with Bonhoeffer-van der Pol neural dynamics.
A prototype system has been developed where EPICS controls beam optics simulations for the CEBAF injector, with the simulation running locally or remotely. The system models a beamline with dozens of magnets and diagnostic devices.
Investigates how many training pilots are needed when a digital twin of a wireless channel is used for channel estimation. The twin is treated as a complementary measurement fused with pilot observations. For the first time, this trade-off is formalized and quantified.
