However, spatiotemporal correlations of wind speed are dynamically influenced by weather conditions, seasonal variations, and diurnal fluctuations, resulting in constantly changing spatiotemporal patterns
A graph neural network (gnn) architecture was used to extract spatial dependencies, with different update functions to learn temporal correlations
Accurate wind power forecasting holds immense significance as it facilitates the development of future generation plans, enhances the economy and reliability of power systems, and promotes the increased. One stream analyses periodic components in the frequency domain with an adapted attentiom mechanism based on fast fourier transform (fft), and another stream similar to the vanilla transformer, which leanrs trend components The proposed model consists of a temporal feature extraction module and a spatial feature extraction module and thus it can capture the temporal and spatial correlations between wind turbine nodes. Accurate and robust wind power forecasting plays a crucial role in ensuring the safety and stability of the power system
