Tip Speed Ratio Optimization: More Energy Production with Reduced Rotor Speed

open access: yesWind, 2022
A wind turbine’s tip speed ratio (TSR) is the linear speed of the blade’s tip, normalized by the incoming wind speed. For a given blade profile, there is a TSR that maximizes the turbine’s efficiency. The industry’s current practice is to impose the same

Wind Turbine Power Curve Design for Optimal Power Generation in Wind Farms Considering Wake Effect

open access: yesEnergies, 2017
In modern wind farms, maximum power point tracking (MPPT) is widely implemented. Using the MPPT method, each individual wind turbine is controlled by its pitch angle and tip speed ratio to generate the maximum active power.
