Zusammenfassung:	The present invention relates to an optimal power distribution network self-healing method in a distribution management system (DMS), which comprises the steps of: obtaining information related to a power distribution network, and based on the obtained power distribution network information, monitoring the power distribution network; when a blackout event occurs in the power distribution network, identifying a type of the power distribution network and calling a linear model corresponding to the identified type; applying the called linear model to a first optimized algorithm to determine a self-healing sequence of the power distribution network; and using a second optimized algorithm to produce a power generation amount of a distributed generation (DG) and an energy storage system (ESS) for each self-healing sequence of the power distribution network. According to the present invention, the method can quickly and stably restore the power distribution network when the blackout occurs in the power distribution network. 본 발명은 배전관리시스템(DMS)에서의 배전망 자가복구 방법에 관한 것으로서, 배전망과 관련된 정보를 획득하고, 상기 획득된 배전망 정보를 기반으로 상기 배전망을 모니터링하는 단계; 상기 배전망에서의 정전 이벤트 발생 시, 해당 배전망의 종류를 식별하고, 상기 식별된 종류에 대응하는 선형 모델을 호출하는 단계; 상기 호출된 선형 모델을 제1 최적화 알고리즘에 적용하여 상기 배전망의 자가복구 시퀀스를 결정하는 단계; 및 제2 최적화 알고리즘을 이용하여 상기 배전망의 자가복구 시퀀스별로 분산전원(DG) 및 에너지저장장치(ESS)의 발전량을 산출하는 단계를 포함한다.
