Large wind farm wake effect


Investigation and validation of wake model combinations for large wind farm modelling in neutral boundary layers


An original approach consisting on the combination of two wake patterns – a single wake model with a neutral boundary layer modification - is investigated in order to model large wind farm wake effect.

Sensitivity studies of boundary layer parameters are carried out to optimise the velocity and power corrections whatever the type of wind farms and the wind directions. Two single wake models (Park and Fast EVM) were combined to a refined boundary layer model and validated against measurements and four standard wake models.

This very promising model combination allows us to take into account the slowdown in large wind farms.
