POWER GENERATION AMOUNT PREDICTION DEVICE, POWER GENERATION AMOUNT PREDICTION METHOD AND PROGRAM

摘要

PROBLEM TO BE SOLVED: To improve an accuracy in prediction of power generation amounts of several wind power generators.SOLUTION: This invention relates to a power generation amount prediction device for predicting power generation amounts at several wind power generators comprising a calculation part for calculating several converted values of the predicted values into power generation amounts on the basis of prediction information indicating prediction values of wind speeds at several zones including locations where several wind power generators are installed; a selecting part for selecting the converted values calculated in regard to a zone corresponding to the converted value where a difference in respect to the actual power generation value of the wind power generators at a predetermined time band of several converted values calculated in the predetermined time band may become minimum in a future time band from the predetermined time band as the prediction value of the power generation amount in the future time band; and an output part for outputting the selected prediction value.SELECTED DRAWING: Figure 3
