DEVICE FOR PREDICTION OF ELECTRICITY GENERATION AMOUNT, METHOD FOR SAME, AND PROGRAM FOR SAME

摘要

An electric-power-generation level predicting apparatus 1 includes a memory unit 20 that stores, as past data relating to a past electric power generation level of an electric power generator, past data containing information at multiple time points in each day, and an predicted-value calculating unit 13 that calculates, as time-series data containing an occurrence probability, an predicted value of the past data relating to an electric power generation level of the electric power generator based on a statistical correlation between different times in the past data or a statistical correlation between locations of the different electric power generators. The predicted-value calculating unit 13 includes a variance-covariance-matrix generator unit 131 that generates a variance-covariance matrix based on the past data, and a random-number generator unit 132 that generates a random number following the probability distribution based on the variance-covariance matrix.
