POWER DEMAND PREDICTION DEVICE AND POWER DEMAND PREDICTION METHOD

To make it possible to improve prediction accuracy of power demand in an arbitrary time zone.SOLUTION: A power demand prediction device for predicting power demand of a user in a first time zone comprises: a prediction value calculation unit that on the basis of consumption power consumed by the user before the first time zone, calculates a first prediction value for power demand in the first time zone and a second prediction value for power demand in a second time zone before the first time zone; an actual value acquisition unit that acquires an actual value of consumption power consumed in the second time zone by the user; and a prediction value correction unit that when the absolute value of a correction reference value obtained by subtracting the actual value from the second prediction value is larger than a predetermined allowable error threshold, subtracts a correction adoption value from the first prediction value. The absolute value of the correction adoption value is smaller than the absolute value of the correction reference value.SELECTED DRAWING: Figure 2 【課題】任意の時間帯における電力需要の予測精度を向上させることができる。【解決手段】第１の時間帯における需要家の電力需要を予測する電力需要予測装置は、第１の時間帯よりも過去に需要家が消費した消費電力に基づいて、第１の時間帯における電力需要の第１予測値、及び第１の時間帯より前の第２の時間帯における電力需要の第２予測値を算出する予測値算出部と、第２の時間帯に需要家が消費する消費電力の実測値を取得する実測値取得部と、第２予測値から実測値を差し引いた補正基準値の絶対値が予め定められた許容誤差閾値よりも大きい場合、第１予測値から補正採用値を差し引く予測値補正部と、を備え、補正採用値の絶対値は、補正基準値の絶対値より小さい。【選択図】図２
