Zusammenfassung:	To support stability of a power system.SOLUTION: A tidal-current fluctuation-related information DB 101 stores tidal-current fluctuation-related information which relates to a tidal-current fluctuation in a power system. A tidal-current fluctuation information DB 102 stores tidal-current fluctuation information which indicates the level of the tidal-current fluctuation. A tidal-current fluctuation prediction model constructing unit 103 constructs a tidal-current fluctuation prediction model 104 by modeling the tidal-current fluctuation-related information and the tidal-current fluctuation information. A tidal-current fluctuation predicting unit 105 predicts a tidal-current fluctuation of a prescribed level or higher with respect to the tidal-current fluctuation-related information in a prediction time period, by using the tidal-current fluctuation prediction model 104. An alert generating unit 106 generates an alert to the tidal-current fluctuation predicted by the tidal-current fluctuation predicting unit 105.SELECTED DRAWING: Figure 1 【課題】電力系統の安定化を支援する。【解決手段】潮流変動関係情報ＤＢ１０１は、電力系統の潮流変動に関係する潮流変動関係情報を格納し、潮流変動情報ＤＢ１０２は、潮流変動のレベルを示す潮流変動情報を格納し、潮流変動予測モデル構築部１０３は、潮流変動関係情報と潮流変動情報との関係をモデル化した潮流変動予測モデル１０４を構築し、潮流変動予測部１０５は、潮流変動予測モデル１０４を用いることにより、予測時間帯における潮流変動関係情報に対する所定レベル以上の潮流変動を予測し、アラート発生部１０６は、潮流変動予測部１０５で予測された潮流変動に対するアラートを発生させる。【選択図】図１
