Abstract

Due to abnormal high temperature, electric power demand has exceeded the backup power reserved for emergency case, hence, resulting in a major power outage. In today's overcrowded cities, the unexpected disruption in energy supply and demand is a major threat to the enormous economic damage and urban malfunctions. Existing methods for estimating the demand of the emergency power source do not lend themselves to predict the actual demand in the spatial dimension of the city. In addition, the reserve power is arbitrarily distributed in the case of emergency. This paper presents a method that predicts the emergency power demand using the spatial distribution of emergency power demand by applying the daily energy consumption intensity and emergency power demand according to urban spatial information and building use.

이상고온 현상으로 전력수요가 예측치를 초과하여 대규모 정전사태가 발생하고 있다. 과밀화된 도시의 경우, 예상치 못한 에너지 수급 차질은 막대한 경제적 피해를 초래하고 도시기능을 마비시키는 중요한 위협요소이다. 기존 비상전력 수요량을 추정하는 방법은 도시의 공간적 차원에서 현실적 수요량을 추정할 수 없어 비상시 예비전력 관리가 용이하지 않다. 본 논문은 도시의 공간정보와 건축물 용도별 평상시 에너지소비 원단위, 비상시 전력수요 원단위를 활용하여 비상전력수요의 공간적 분포를 규명하고, 이를 활용하여 비상전력 수요량을 예측하는 방법론을 제시한다.
