PV output prediction support device, PV output prediction device, PV output prediction support method, and PV output prediction support program

摘要

PROBLEM TO BE SOLVED: To provide a PV output prediction support device, a PV output prediction device, a PV output prediction support method, and a PV output prediction support program for improving the accuracy of PV output prediction. SOLUTION: A storage unit 12 has information on a solar radiation distribution of the past day in a target area, a measurement result of the solar power output of the past day, and a plurality of prediction models used for prediction of the solar power output in the past day. Stores the prediction result. The extraction unit 15 acquires information on the solar radiation distribution of the prediction target date, and extracts similar days having a solar radiation distribution similar to the prediction target date from the selection target days included in the predetermined period among the past days. The prediction error acquisition unit 16 acquires the prediction error for each prediction model on the similar day extracted by the extraction unit 15, based on the measurement result and the prediction result for each prediction model. The notification unit notifies each prediction error acquired by the prediction error acquisition unit 16 as a prediction error of each prediction model for prediction of the photovoltaic power generation output on the prediction target day.
