区块链在分布式能源交易的应用架构及安全性分析OACSTPCD

With the development of the power industry,electric energy gradually restores the attributes of commodi-ties.The power trading model has gradually evolved from centralized to distributed,leading to hidden risks such as insufficient mutual trust among market participants,low data security,and difficulty in management.This paper ana-lyzes the application models of different block chain technologies in the power trading market.This paper evaluates the security of power transaction block chain information from the perspective of quantitative analysis.Combined with the technical characteristics of the block chain and the communication mechanism of power transaction,the invulner-ability and survivability indicators are established,and the modeling and quantitative analysis of the security of the"weakly centralized"block chain communication network of power transaction.The analysis results of the calculation examples show that the"weakly centralized"communication architecture of distributed power transaction is more ef-fective than the traditional centralized"star"communication architecture when the reliability value ranges from 0.90 to 0.99.The former increases by 2.67 to 31.07％,and the actual survival of the former increases by 5.31 to 5.95 times than the latter.
