Zusammenfassung:PROBLEM TO BE SOLVED: To provide a method etc., for analyzing prediction of photovoltaic power generation.SOLUTION: The method may include obtaining the test data set of historical radiant quantity at the position of a photovoltaic power generation system, and normalizing the test data set on the basis of a radiant quantity fine weather model at the position. The method may further include clustering the test data set into a plurality of weather classes each including a set of characteristics, obtaining the prediction of radiant quantity with regard to a given future point of time in the photovoltaic power generation system, classifying the prediction into one of the plurality of weather classes, and determining the confidence interval of prediction on the basis of a set of characteristics of one of the plurality of weather classes. The method may further include carrying out, on the basis of the confidence interval of prediction, one of the increased output and the decreased output of an energy generation source that takes the place of solar energy.SELECTED DRAWING: Figure 3 【課題】太陽光発電予測を解析する方法等を提供する。【解決手段】方法は、太陽光発電システムの位置での歴史的な放射量のテストデータセットを得、その位置での放射量の晴天モデルに基づきテストデータセットを正規化することを含んでよい。方法は、テストデータセットを、夫々が特性の組を含む複数の気象クラスにクラスタリングし、太陽光発電システムでの所与の将来の時点についての放射量の予測を得、予測を複数の気象クラスのうちの1つに分類し、複数の気象クラスのうちのその1つの特性の組に基づき予測の信頼区間を決定することを更に含んでよい。方法は、予測の信頼区間に基づき、太陽エネルギに代わるエネルギの発生源の増加出力又は減少出力のうちの一方を実施することを更に含んでよい。【選択図】図3
