NEW METHODS FOR SMART METER DIAGNOSTICS PRESENTED BY R&D NESTER AT ICECCME 2025
The objective of R&D Nester's project "QUANTUM - Research on Metrological Characteristics of Quantum Voltage Chip and Traceability Application Verification" is to enhance the accuracy and reliability of digital metering systems through the development and application of programmable quantum voltage chips, supporting metrology in smart grid contexts. More specifically, one of the project's tasks aimed to improve the monitoring and evaluation of digital metering equipment used in smart grids. This included building a platform to compare digital and analog metering systems and developing methods to detect and analyze measurement errors.
This project is developed by R&D Nester in cooperation with China Electric Power Research Institute (CEPRI).
As a result of this work, the R&D Nester team presented two scientific papers at the 5th International Conference on Electrical, Computer, Communications and Mechatronics Engineering (ICECCME 2025), held in hybrid format in Zanzibar, Tanzania, from 16 to 19 October 2025.
The first paper: "Unveiling Hidden Patterns in Smart Meter Errors Using Spectral Methods":
- Explores how spectral analysis can uncover periodic structures hidden within metrological error signals of smart and analog meters.
- Using Fourier and Short-Time Fourier Transform (STFT) techniques, the study revealed stable harmonic patterns in meter errors, corresponding to daily operational cycles and systematic influences - offering new diagnostic insights into metrological behavior.
- This methodology is suitable for periodic errors.
The second paper: "Technology-Divergent Anomaly Detection in Smart Meters: Adaptive LSTM-Autoencoders for Digital vs. Analog Error Signals":
- Introduces a machine learning approach for detecting metrological anomalies in energy meters using adaptive Long Short-Term Memory - autoencoders.
- This methodology is suitable for non-periodic errors.
Both papers contribute to advancing metrological intelligence and precision monitoring in energy measurement systems, strengthening R&D Nester's research in the field of smart grid metrology.
ICECCME 2025 brings together industry professionals, academics, and engineers to exchange information and ideas on electrical, computer, communications, and mechatronic engineering.
The proceedings are available in IEEE Xplore,
Scopus and Ei Compendex.
