According to an embodiment of the present invention, a power demand prediction method of a power demand prediction device for a special day comprises the following steps of: predicting power demand on a special day to be predicted by applying power demand data of a past special day to a fuzzy linear regression analysis model; determining whether temperature sensitivity is corrected based on a forecast temperature of the special day to be predicted; calculating temperature sensitivity of the special day according to the determination result to correct the power demand of the predicted special day; and estimating and reflecting the amount of BTM solar power generation to the corrected power demand of the special day. 본 발명의 일 실시예에 따른 특수일의 전력수요예측 장치의 전력수요예측 방법은 과거 특수일의 전력수요 데이터를 퍼지 선형회귀분석 모델에 적용하여 예측하고자 하는 특수일의 전력수요를 예측하는 단계; 상기 예측하고자 하는 특수일의 예보기온에 기초하여 기온민감도 보정 여부를 판단하는 단계; 상기 판단결과에 따라, 특수일의 기온민감도를 산출하여 예측된 특수일의 전력수요를 보정하는 단계; 및 보정된 특수일의 전력수요에 BTM 태양광 발전량을 예측하여 반영하는 단계를 포함한다.
