Power Curve Modelling for Wind Turbines [PDF]
2017 UKSim-AMSS 19th International Conference on Computer Modelling & Simulation (UKSim), 2017 The wind turbine power curve WTPC describes the relationship between wind speed and turbine power output. Power curve, provided by the manufacturer is one of the most important tools used to estimate turbine power output and capacity factor. Hence, an accurate WTPC model is essential for predicting wind energy potential.

Constrained power reference control for wind turbines [PDF]
Wind Energy, 2021 Abstract The cost of wind energy can be reduced by controlling the power reference of a turbine to increase energy capture, while maintaining load and generator speed constraints. We apply standard torque and pitch controllers to the direct inputs of the turbine and use their set points to change the power output and reduce generator ...
