A power usage decomposition system according to an embodiment of the present invention includes: a DB which receives power data from smart meters installed in the house, receives data from external factors which affect power data from an external server, and stores the data in time series; an extraction unit which extracts characteristic variables of the standard resolution time interval from the power data stored in time series and data according to external factors; and an analysis unit which decomposes the total power usage in the home by inputting the characteristic variables into a hidden Markov model (HMM)-based power usage decomposition model which takes into account the dependency of external factors to infer the hidden power use state. 본 발명의 실시예에 따른 전력 사용량 분해시스템은 댁내에 설치된 스마트미터로부터 전력데이터를 수신하고, 외부서버로부터 전력데이터에 영향을 주는 외부요인에 따른 데이터를 수신하여, 시계열 저장하는 DB, 시계열 저장되는 전력데이터 및 외부요인에 따른 데이터로부터 기준해상도 시간간격의 특성변수를 추출하는 추출부 및 특성변수를 외부요인의 의존성을 고려한 HMM(Hidden Markov Model)기반 전력사용 분해모델에 입력하여 은닉된 전력사용 상태를 추론하여 댁내의 총 전력사용량을 분해하는 분석부를 포함한다.
