Claim 8:
9. A wind speed-tip speed ratio wind energy control method for a PMSG based wind turbine, wherein the PMSG based wind turbine comprises a controller module, and a drive train comprising a generator, a rotor, a gear box, high-speed shaft, and a low-speed shaft, and one or more blades; wherein the controller module comprising a memory and a processor; wherein the gearbox connects the low-speed shaft to the high-speed shaft which is attached to the generator, the method comprising:
generating a data set including at least 120 samples each of wind velocities and tip speed ratios at wind speeds between 3 to 19.4 m/s;
determining a maximum power and an optimum rotor speed (ωopt) for every sample of wind velocity in the data set;
training a neural network (NN) model using the data set in which each sample of wind velocity in the data set is fed as an input and the determined optimum rotor speed and the determined maximum power are output from the NN model,
testing the NN model with random input wind speed; and
controlling the rotor of the PMSG based wind turbine based on a current wind velocity and the optimum rotor speed determined by the NN model.
