Renewable energy sources (RES) such as distributed photovoltaic (PV) and wind turbine (WT) provide uncertain and stochastic active power supply. Then the large amount of RES brings great challenges to the operation of distribution network. A distributionally robust optimal dispatch method considering multiple source-storage coordinated interaction for distribution network is proposed in this paper. Based on the distributionally robust optimization theory,the dispatch decisions of traditional discrete devices,RES and energy storage are optimized coordinately to improve the economy and safety of distribution network operation,and thus realizing the effective balance of conservativeness and robustness for distribution network dispatch decision. Firstly,with consideration of multiple source-storage coordinated interaction,the optimal distribution network dispatch model is constructed and reformulated as the mixed integer second-order cone programming form. Secondly,the RES output scenarios are utilized to describe the uncertainty while the distributionally robust optimal dispatch model of distribution network considering multiple source-storage coordinated interaction is constructed,after which the column and constraint generation algorithm are employed for model solution. Finally,it is carried out based on the PG&E 69 node system to verify the feasibility and accuracy of the proposed method.
