A Study on Forecasting Wind Speeds Using Bidirectional SOM

New energy is paid to attention now. The wind-force is one of the new energy and is unlimited. We paid attention to the domestic small aero generator, especially, with power assistance type. In order to operate the wind generator with more efficiency than before, we have tried to forecast the wind by both the Conventional basic SOM and Bi-directional SOM in this study. We evaluated experiments by CV method. On the forecast error rate, Bi-directional SOM predicated the wind speed every season without the change of the extreme error rate. Basic SOM was less than Bi-directional SOM in spring and summer, but Bi-directional SOM lowers in autumn and winter.
