Potential of Dynamic Wind Farm Control by Axial Induction in the Case of Wind Gusts

Florian Bürgel, Robert Scholz, Christian Kirches, and Sebastian Stiller

Abstract. Wind turbines organized in wind farms will be one of the main electric power sources of the future. Each wind turbine causes a wake with a reduced wind speed. This wake influences the power of downstream turbines. Therefore, there is a strong interaction between the individual wind turbines in a wind farm. This interaction is an opportunity for optimal control to maximize the total power and decrease the load (i.e., tower activity and pitch activity) of a wind farm. We use the already known axial-induction-based control but investigate its potential in the case of a wind gust using mathematical optimization. This case is particularly interesting because a wind gust requires a dynamic control reaction and the consideration of the time delay with which downstream turbines are affected. In particular, this enables to reduce the tower load of downstream wind turbines by dynamic axial-induction-based control of an upstream turbine.

Short summary
Wind turbines are an important electric power source. Usually, they are organized in wind farms. Thereby, each wind turbine causes a so-called wake with a reduced wind speed. This can influence following wind turbines and is an opportunity to optimize the operation of each wind turbine. A wind gust usually makes the tower oscillate. We control a wind turbine in a way such that the following turbine significantly less oscillates. Thereby, we also paid attention to the power of the wind turbines.
