Choosing the right method depends on data availability, interpretability needs, and real-time constraints, with hybrid models offering a balanced approach.
Case Study: AI-Driven Maintenance in Power & Energy Systems
Challenge: Power and energy systems (e.g., transformers, wind turbines) are critical infrastructure where failures lead to severe consequences. Challenges include limited data, noisy observations, out-of-distribution generalization issues, and stringent safety/interpretability requirements for model outputs.
AI Solution: AI algorithms are deployed for RUL prediction of wind turbine components using RNNs/LSTMs and fault location in distribution networks via GNNs. To overcome data and interpretability issues, Physics-Informed Neural Networks (PINNs) integrate mechanistic models, while Knowledge Graphs (KGs) organize domain knowledge for explainability. Federated Learning enables collaborative condition assessment across different wind farms, addressing data silos and privacy concerns.
Impact: Enhanced physical consistency and extrapolation capability of predictions, improved traceability of diagnostic evidence, and strengthened model generalization across diverse operational conditions, ensuring higher reliability and safety in critical energy infrastructure.
