The micro-grid can realize the effective integration of distributed power sources and reduce the impact of intermittent fluctuations of new energy sources on the main grid.In order to better realize the optimized operation of the micro-grid,a micro-grid power transaction model based on block chain and game theory is proposed in this paper to better realize the optimized operation of the micro-grid.Firstly,the overall infrastructure of the micro-grid peer-to-peer(P2P)power trading system is built,and the block chain network and smart contract logic are designed.Secondly,the benefits of each user in the micro-grid are analyzed to optimize the user matching during transaction process.Then,the cooperative game algorithm is used to build a micro-grid P2P electricity pricing model for power transactions.Finally,the simulation and analysis results show that the block chain-based technology and cooperative game transaction model can effectively realize power transactions between users,which is conducive to building an open,transparent,and efficient market environment,and can ensure the maximum benefits of users.
