During the last two weeks of May 2018, the fourth test campaign at Politecnico di Milano Wind Tunnel has been completed. Two different open-loop wind farm controllers, aimed at increasing the total power output, have been analyzed. The first one is based on a wake redirection method, whereas the second on a fast wake recovery strategy. Both controllers proved effective as means to increase the total harvested power.
During this campaign, three wind turbine models provided by the Technical University of Munich have been used in an aligned configuration, and two different boundary layers, typical for an onshore and an offshore condition, have been reproduced.
