Estimation of wind power generation is the key step in turbine-site matching and wind power cost analysis. In order to estimate the wind power accurately, radial basis function (RBF)neural network is used to estimate the energy output of wind power plant. The modeling is based on the historical data from 18 meteorological stations of Chinese Tai- wan and 26 meteorological stations of Republic of Korea, then their energy outputs are estimated by themselves and among each other. Because the wind speed and generation hours are the main factors a...
