摘　　要：Considering the uncertainty of wind power generation(WPG)and the specific operation behaviors of trading microgrids,this paper presents a blockchain-enabled robust-game electricity transaction model in a multi-microgrid system(MMS)to obtain optimal bidding-dispatching strategies,and achieve a transparent and decentralized electricity transaction.Combining blockchain technology and a non-cooperative game model,the established MMS electricity transaction architecture provides a complete information game environment for all game microgrids and facilitates the transparent,efficient,orderly,spontaneous management of MMS electricity transactions without the intervention of a third trusted party.Based on the distributed transaction architecture,an MMS robust-game model is presented to achieve the optimal day-ahead bidding-dispatching(DA-BD)strategies,in which the individual microgrid two-stage adjustable robust-game bidding-dispatching(ARG-BD)model characterizes the WPG uncertainty by employing uncertain interval and adjustable robust parameters.The binary expansion method,duality theory,big M method,and column-and-constrain generation algorithm(C&CG)are employed to solve the individual microgrid two-stage ARG-BD model.An alternating robust-game procedure integrating the C&CG algorithm and non-cooperative game model is developed to solve the MMS robust-game model.Case studies demonstrate the transparent and decentralized transaction,economic mutual benefits,and solution robustness of the presented method.
