摘要
Abstract
The increasing proportion of renewable energy integration has introduced more and more uncertain factors into the operation regulation of DC microgrid.The existing robust optimization scheduling results are too conservative,and the economic performance of the scheduling scheme is poor.Based on the probability distribution characteristics of the typical historical data,a new multi-probability interval uncertainty set is proposed to accurately describe the source and load fluctuations by fitting the confidence intervals of different source and load powers.Based on the proposed novel uncertainty set,a robust optimization scheduling model for DC microgrid is constructed.The column and constraint generation(C&CG)algorithm is used to simplify the model,and an optimization scheduling scheme that takes into account the economy and stability of power grid is obtained.Finally,by comparing the scheduling economy and accuracy of various uncertainty set description methods,the validity and feasibility of the proposed optimization method are verified.关键词
