Design And Implementation Of Distributed Energy Trading Platform Architecture Based On Blockchain Technology

With the development of national economy and the growth of power demand,distributed energy has gradually become an important part of the energy market.With the advantages of decentralization,openess and traceability,Blockchain technology is a great solution for the problem of distributed energy transactions with samll quantity,high frequency,large amount of data and non-existent trusted center.In this thesis,the consortium blockchain is used in the form of hyperledger in the distributed energy trading,and a new distributed energy trading platform is proposed to implement the automation of transaction settlement by designing the intelligent contracts of transaction matching mechanism and credit mechanism.A non cooperative game model based on power suppliers and consumers is established by the combination of staged bilateral auction and game theory,and the Nash equilibrium is solved by the model based on ant colony algorithm to maximize the revenue of each subject in the market.The matching results are packed in the blockchain and publicized in the whole network,so that the whole transaction system could run efficiently,transparently,safely and automatically without a trusted center.At the same time,the security marking mechanism based on consortium blockchain and the improved credit scoring system are introduced to supervise and restrict the buyers and sellers,then the distributed energy supervision model based on blockchain is constructed.Through theoretical analysis and simulation,it is proved that the model can supervise the honest transaction of users,effectively reduce the transaction risk of sellers and buyers,and make up for the disadvantages of the existing trust mechanism.According to the proposed model,a distributed energy trading platform based on consortium blockchain with Hyperledger Fabric is implemented and the effectiveness of the platform is verify.
