Wind Power Prediction Based on Wind Farm Output Power Characteristics Using Polynomial Fitting

As large-scale wind power integrated into systems, a reliable wind power prediction is of great significance for systems´ safe and reliable operation. In this paper, based on the single wind turbine output characteristics, the output power characteristics of the whole wind farm have been analyzed. With the analysis of historical power and wind speed data, using the methods of quadratic polynomial and cubic polynomial fitting, the model based on the output power characteristics has been established. The actual system numerical examples have been used to test and compare the results of these fitting methods.
