초록

본 논문은 분산전원이 연계된 배전계통의 신뢰도를 평가할 수 있는 해석적 기법과 그에 맞는 분산전원의 모델을 제시한다. 분산전원은 송전계통에 연계된 대규모 발전기와는 다른 운영방식을 가지기 때문에 기존의 기법과는 다른 해석기법과 모델을 필요로 한다. 제시되는 신뢰도 해석기법은 Monte-Carlo 시뮬레이션에 비해 간단하면서도 피크부하를 사용하는 해석기법에 비해 정확하기 위해 Load Duration Curve를 사용하였고, 최종적으로는 사례연구를 통해 제시된 기법의 정확성을 입증하였다.

Unlike the large sized generations of transmission system, the distributed generations have complexities in analyzing and determining model. This paper resents an analytical method for the reliability evaluation of distribution system, including the distributed generations. The method using Load Duration Curve model is simpler than the Monte-Carlo Simulation and is more accurate than that using peak load model. The modeling of distributed generation to analysis reliability of customers using LDC is proposed in this paper, and is compared with the MCS method as a result of case studies.
