In particular, we follow the idea of modelling a turbine's performance as a power curve where any power outputs that fall off the curve can be seen as performance errors. ...
With the rising costs of conventional sources of energy, the world is moving towards sustainable energy sources including wind energy. ...
We use a 70%-30% split of the data set of training and testing and find that a Medium Gaussian Kernel based Support Vector Regression (SVR) model achieves a minimal square error (MSE) of 0.098063 using ...
