This article presents an approach for applying Physics-Informed Neural Networks (PINNs) for modeling wind fields in wind farms. The addressed problem is reconstructing the inflow velocity field for a wind turbine. Several PINN variants are implemented and validated over a real-world case study, trained with sparse numerically simulated velocity data. Results demonstrate that the proposed PINNs can accurately assimilate the numerical simulation data, and compute accurate solutions. The proposed approach is a viable alternative for modeling wind fields in wind farms, requiring significantly lower execution times than standard numerical/simulation methods.

Abstract
This article presents an approach for applying Physics-Informed Neural Networks (PINNs) for modeling wind fields in wind farms. The addressed problem is reconstructing the inflow velocity field for a wind turbine.

Results demonstrate that the proposed PINNs can accurately assimilate the numerical simulation data, and compute accurate solutions. The proposed approach is a viable alternative for modeling wind fields in wind farms, requiring significantly lower execution times than standard numerical/simulation methods.
