GENERATED POWER PREDICTION DEVICE, METHOD FOR PREDICTING GENERATED POWER, AND PROGRAM FOR PREDICTING GENERATED POWER

摘要

PROBLEM TO BE SOLVED: To facilitate the prediction of power generated by a photovoltaic power generation device with environments surrounding the photovoltaic power generation device or power generation restrictions depending on states of a site to which the photovoltaic power generation device is connected taken into account.SOLUTION: A generated power prediction device comprises: a generated power history information storage part for storing generated power history information which associates generated power achievement values of a photovoltaic power generation device in chronological order in the past with weather records in chronological order in the past; a similarity determination part for determining a weather record similar to a weather indicated by a weather forecast on a prediction day from the weather records in the generated power history information; a generated power achievement values acquisition part for acquiring a generated power achievement value to be used for predicting power generated by the photovoltaic power generation device on the prediction day from the generated power history information on the basis of a determination result obtained by the similarity determination part; and a generated power prediction part for predicting the power generated by the photovoltaic power generation device on the prediction day by using the generated power achievement value acquired by the generated power achievement values acquisition part.
