摘要：Scenario-based stochastic unit commitment (SBSUC) algorithm is an effective approach to solve unit commitment problem considering wind power integration. The results of SBSUC have a close relation with the formation mode of scenario set. So, how to construct a re asonable scenario set is a key problem for SBS-UC. In this paper, using the same SBS-UC model, the scheduling results of two different scenario sets are compared Test scenario set 1 is obtained according to the forecasted probability distribution of each period, without considering the time-domain correlation information of wind farm generation. Accordingly, test scenario set 2 contains time-domain correlation information of wind farm generation through estimating the correlation coefficient matrix. This paper compares the scheduling results and emphasizes the important role of timedomain correlation information of wind farm generation for unit commitment considering wind power integration.
