Abstract：The increasing proportion of renewable energy integration has introduced more and more uncertain factors into theoperationregulation ofDC microgrid.Theexistingrobustoptimizationschedulingresultsare too conservative，and theeconomicperformance of the scheduling scheme is poor.Basedon the probabilitydistribution characteristicsof thetypical historicaldata，anewmulti-probabilityintervaluncertaintysetisproposed toaccurately describe the source and load fluctuationsby fiting theconfidence intervals of different source and load powers. Based on the proposed novel uncertainty set，a robust optimizationscheduling model forDC microgrid is constructed.The column and constraint generation（C&CG）algorithmis used to simplify the model，and an optimizationscheduling schemethat takesintoaccounttheeconomyand stabilityofpowergrid isobtained.Finally， by comparing the scheduling economy and accuracy of various uncertaintyset description methods，the validity and feasibility of the proposed optimization method are verified.
