Accurate day-ahead forecasting of photovoltaic (PV) power generation is crucial for system scheduling. To overcome the inaccuracies and inefficiencies current PV models, this paper introduces Recurrent Fourier-Kolmogorov Arnold Network (RFKAN). Initially, recurrent kernel nodes are employed to investigate interdependencies within sequences. Subsequently, Fourier series applied extract periodic features, enhancing accuracy training speed. Ablation studies conducted using data from a plant in Tieling City, Liaoning Province, validate effectiveness these two structural enhancements. Comparative experiments with baseline state-of-the-art models further underscore efficiency RFKAN. The results indicate that RFKAN achieves best performance grid depth 100 an input sequence length 2, reducing RMSE MAE by at least 5%, increasing CORR 2%, decreasing time 24% compared advanced models.

Accurate time series forecasting is crucial in fields such as business, finance, and meteorology. To achieve more precise predictions effectively capture the potential cycles stochastic characteristics at different scales series, this paper optimizes network structure of Autoformer model. Based on multi-scale convolutional operations, a feature fusion proposed, combined with date–time encoding to build MD–Autoformer model, which enhances model’s ability information scales. In tasks across four fields—apparel sales, meteorology, disease—the proposed method achieved lowest RMSE MAE. Additionally, ablation experiments demonstrated effectiveness reliability method. Combined TPE Bayesian optimization algorithm, prediction error was further reduced, providing reference for future research methods.
