Cover Story: Accurate prediction of wind turbine power output is vital for efficient renewable generation and grid integration. However, real power curves are highly non-linear, with abrupt cut-in, rated, and cut-out transitions that plain multilayer perceptrons (fully connected feedforward neural networks) often smooth out due to spectral bias. This work models the power curve of a 1 kW turbine using an open access 10-minute dataset from 2011 and compares a conventional multilayer perceptron trained on normalized wind speed with one augmented by Fourier feature encoding. By mapping wind speed into a sinusoidal feature space, the Fourier-enhanced model captures sharp regime changes more faithfully and delivers markedly lower prediction error, demonstrating the value of Fourier features for data-driven turbine power modelling.
