Enhancing Electricity Price Prediction Accuracy With an Attention Mechanism‐LSTM Hybrid Model

Engineering Reports, Volume 8, Issue 3, March 2026.
This study proposes an ATT‐LSTM framework for short‐term electricity price forecasting, integrating meteorological data, historical prices, and system load. With careful preprocessing, feature engineering, and attention mechanisms, the model delivers accurate and interpretable predictions of price volatility.
