Generation quantity predicting device, power generation prediction method, and power generation prediction system

摘要

PROBLEM TO BE SOLVED: To identify a variation tendency of a power generation amount in a specific area while considering wind directions to enable accurate prediction of the power generation amount.SOLUTION: A power generation amount prediction device comprises: a storage unit for previously storing first solar radiation amount past information showing a past solar radiation amount of a first location positioned on the windward side of a specific area and second solar radiation amount past information showing a past solar radiation amount of a second location that is opposite to the first location while interposing the specific area between the first location and second location and is positioned on the leeward side of the specific area; a variation tendency calculation unit for identifying a variation tendency of a solar radiation amount of the specific area between the first location and second location, on the basis of first solar radiation amount past information and second solar radiation amount past information corresponding to the first solar radiation amount past information; and a power generation amount prediction unit for calculating a predicted solar radiation amount of the specific area on the basis of a first actually measured solar radiation amount of the first location and the variation tendency as well as for predicting a power generation amount of a photovoltaic power generation facility installed in the specific area on the basis of the predicted solar radiation amount.SELECTED DRAWING: Figure 2
