This letter proposes a proactive scheduling for resilience enhancement of microgrids (MGs). Just ahead of the flood arrival, the MG is shifted to a state less impacted and stressed by the upcoming event. To do this, vulnerable components are first recognized. Tripping out all vulnerable components, proactive measures are employed to minimize the preventive load curtailment. The solution is then applied as the proactive schedule of MG which is robust against the flood threat. The effectiveness of the proposed method is examined on a real-scale MG.
