Abstract—It is difficult to predict the power generation amount of wind turbines because it is depending on weather condition. However it is important to predict wind power generation amount accurately, because it is possible to maximize the utilization of wind turbines, and also establish more effective operation plan of grid. The purpose of this study is to increase the accuracy of prediction of the power generation amount. To increase accuracy, we built the 3 dimensional weather research and forecasting model that is the most applicable to our developing district environment. In case of short-term prediction within 6 hours, to overcome the weakness that cannot reflect the regional characteristics for particular areas enough, we predicted weather information considering statistical characteristics such as weather pattern change information of wind plants. Using the result of weather prediction as a basic data, we computed the power generation amount by plants and wind generators. In the proposed approaches, inaccuracies are analyzed based on the combination of physical model and statistical model. The result of the analysis showed 15.7% (within 24 hours), and 17.5% (within 48 hours) error rate.
