Hybrid Transformer Prognostics Framework for Enhanced Probabilistic Predictions in Renewable Energy Applications

Aizpurua Unanue, Jose Ignacio; Perez Ramirez, Ibai Aner (IEEE, 2022)

The intermittent nature of renewable energy sources (RESs) hamper their integration to the grid. The stochastic and rapid-changing operation of RES technologies impact on power equipment reliability. Transformers are key ...
Residual-based attention Physics-informed Neural Networks for spatio-temporal ageing assessment of transformers operated in renewable power plants

Ramirez, Ibai; Pino Gómez, Joel; Pardo, David; Sanz Alonso, Mikel; Ortiz, Álvaro; Morozovska, Kateryna; Aizpurua Unanue, José Ignacio (Elsevier Ltd, 2025)

Transformers are crucial for reliable and efficient power system operations, particularly in supporting the integration of renewable energy. Effective monitoring of transformer health is critical to maintain grid stability ...
