Solar power generation forecasting device

Abstract

To realize a solar power generation amount prediction device with improved prediction accuracy of a power generation amount.SOLUTION: A solar power generation amount prediction device 100 includes a power generation amount prediction data output learning device 3 that performs machine learning on a correlation between weather forecast data 4 stored in a weather forecast database 1 and an actual power generation amount 2 from sunlight stored in an actual power generation amount database 2 and predicts a power generation amount by the sunlight. The solar power generation amount prediction device 100 further includes a solar power generation amount prediction unit 23 that corrects, on the basis of power generation amount prediction error data 6 indicating an error between a power generation amount prediction value 5 predicted by the power generation amount prediction data output learning device 3 on the basis of current forecast data 40 which is a current weather forecast and an actual power generation amount from the sunlight, the power generation amount prediction value 5 and predicts the power generation amount by the sunlight.SELECTED DRAWING: Figure 1
