Temporal Graph Neural Networks for Early Anomaly Detection and Performance Prediction via PV System Monitoring Data

Effective performance prediction and timely anoma ly detection are paramount to ensuring the long - te rm efficiency, reliability, and economic viability of these systems. Traditional monitoring methods, often based on simple thresho lds or statistical rules, frequently fail to account for the complex interplay of environmental and operational variables that affect PV performance. These methods may lead to high rates of false positives or, more critically, miss subtle but significant a nomalies that can indicate underlying system faults. To overcome these limitations, advanced data - drive n approaches are essential. Machine learning and deep learning models have shown promise in this field, offering the ability to learn complex, non - linear relationships from vast datasets.
