Abstract: This article proposes a power network management system based on blockchain technology to address the difficulties in distributed energy management in smart grids and power resource dispatching. Ethereum is used as the development platform to build a blockchain for power interaction management which mainly involves distributed energy transactions. In order to guarantee the rationality of energy transactions in the grid, this article presents a distributed power dispatching strategy using K-means clustering algorithm and particle swarm optimisation (PSO) algorithm. Finally, the distributed power matching transactions are completed in the power interaction management blockchain with the presence of power operation smart contracts. The experimental results show that the consensus mechanism and power dispatching strategy designed in this paper effectively solve the matching problem in distributed power trading. The application of the power operation smart contract further promotes the success rate of the transaction and effectively reduces its time consumption.

Keywords: smart grid; distributed energy; power network management system; power interactive management blockchain; smart contract.
