An Improved iTransformer for Day-Ahead Photovoltaic Power Forecasting Based on Frequency Domain and Periodic Modeling

Photovoltaic (PV) power day-ahead forecasting is crucial for grid dispatch and energy management, yet its accuracy is severely challenged by the nonstationarity and multiscale periodicity of the power series. To address the limitations of existing transformer models in explicit periodic modeling and handling nonstati...
