Abstract
In this paper
a short-term wind speed forecasting method based on local weighted linear regression is proposed
which is produced new wind data set by kernel function. Then a linear regression model is build based on the new set and apply the model to forcesting the short-term wind speed. Short-term wind speed forecasting based on local weighted linear regression model is established and simulated with the measured data of a wind farm
and compared with the traditional ARIMA model and BP neural network prediction model. The result shows the model proposed in this paper is efficacy
and provide a new method for the wind speed forecasting.
