Llm-assisted physics-guided spatiotemporal graph learning for power meteorological disaster evolution

Extreme meteorological events—such as winter cold waves, ice accretion, and typhoons—are increasingly becoming primary triggers that threaten the safe and stable operation of power systems. Their disaster-causing processes exhibit strong spatial correlations and multi-stage tempo...

Diagnosis of abnormal voltage in individual cells and fault trend prediction in energy storage power stations

Abstract During the operation of energy storage power stations, individual cells are prone to voltage inconsistency and abnormal voltage fluctuations due to manufacturing variations, inconsistent aging degrees, and changes in operating conditions. To address this issue, this stud...
