High-Frequency Digital Twin of SWER Network for PLC and Sensing
US & West ·
A high-frequency (up to 300 kHz) digital twin of an operational SWER network is developed to model narrowband PLC communication channels. The model integrates a segment-by-segment transmission line model with VNA measurements, replacing uniform assumptions with empirical component responses.
Why it matters
This is important for assessing and optimizing communication technologies in smart grids, contributing to reliability and efficiency of power systems.
Channel Modeling of Single Wire Earth Return Networks for Narrowband Power Line Communication and Sensing: A Field-Validated High-Frequency Digital Twin
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.
The article discusses an architecture of a digital twin for nuclear systems, integrating multiple models (physics-based and data-driven) to support decision making, state estimation, predictive control, and real-time data processing. The twin must synchronize with the physical facility faster than its operational cycle.
The company 'Aktiv' has finalized a document based on the foresight session held in Moscow in March 2025. The document includes strategic recommendations and forecasts for the industry development until 2040.
