Title:
PV OUTPUT PREDICTION SUPPORT DEVICE, PV OUTPUT PREDICTION DEVICE, PV OUTPUT PREDICTION SUPPORT METHOD AND PV OUTPUT PREDICTION SUPPORT PROGRAM
Document Type and Number:
Japanese Patent JP2020108188
Kind Code:
A
Abstract:
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, which can improve prediction precision of PV output.SOLUTION: A storage section 12 stores information of a solar radiation distribution on a past day in a target area, a measurement result of photovoltaic power generation output on the past day and a prediction result on the past day for each of a plurality of prediction models used for predicting the photovoltaic power generation output. An extraction section 15 acquires information of the solar radiation distribution on a prediction target day and extracts a similar day having the solar radiation distribution similar to the prediction target day from selection target days included in a prescribed period in the past days. A prediction error acquisition section 16 acquires a prediction error for each prediction model in the similar day extracted by the extraction section 15 on the basis of the measurement result and the prediction result at every prediction model. A notification section notifies the respective prediction errors which the prediction error acquisition section 16 acquires as the prediction errors of the respective prediction models of prediction of the photovoltaic power generation output on the prediction target day.SELECTED DRAWING: Figure 2
