A Transformer approach for Electricity Price Forecasting
This work addresses electricity price forecasting for power system operators, but it appears incremental as it applies an existing Transformer method to this domain without major innovations.
The authors tackled electricity price forecasting by applying a pure Transformer model without recurrent networks, demonstrating that attention mechanisms alone can capture temporal patterns. Their approach outperformed traditional methods, though no specific numerical improvements were provided.
This paper presents a novel approach to electricity price forecasting (EPF) using a pure Transformer model. As opposed to other alternatives, no other recurrent network is used in combination to the attention mechanism. Hence, showing that the attention layer is enough for capturing the temporal patterns. The paper also provides fair comparison of the models using the open-source EPF toolbox and provide the code to enhance reproducibility and transparency in EPF research. The results show that the Transformer model outperforms traditional methods, offering a promising solution for reliable and sustainable power system operation.
