복원력 향상을 고려한 차세대 전력망의 예비타당성 분석 모델 개발

초록

Recently, various studies have been conducted on enhancing the resilience of the power grid in order to effectively respond to low-probability, high-impact events such as natural disasters or catastrophes. This paper proposes a feasibility study model that focuses on assessing the resilience of the next-generation power grid. The resilience enhancement of the power grid is considered with constraints in the proposed model, and it is estimated by the expected value of resilience enhancement (EoRE) considering the uncertainty of fault situations. In the case study, the feasibility study incorporates not only the capacity of distributed generators (DG) but also analyzes the optimal locations for DG to improve the resilience of the power grid. The analysis results of EoRE demonstrate that the location of DG for enhancing power grid resilience is closely related to the grid configuration.
