a wind power plant, including to increase the rotor area and/or increasing the distance between the outermost part of at least one blade and the tower by regulating, during operation, the pitch of a blade about a pitch axis which is angled relative to the longitudinal axis of the blade.T...
Here, we experimentally demonstrate the potential of individual blade pitching as a control strategy and explain the flow physics that yields the performance enhancement. We perform automated experiments using a scaled-down turbine model coupled to a genetic algorithm optimiser to identify optimal ...
