Blockchain-Based Power Transaction Method for Active Distribution Network

A blockchain-based power transaction method is proposed for Active Distribution Network (ADN), considering the poor security and high cost of a centralized trading system. Firstly, decentralized blockchain structure ADN built information kept in blocks. Secondly, needs between users suppliers ADN, an energy request mechanism proposed, optimization objective function designed by integrating aware requests storage requests. Finally, particle swarm algorithm used multi-objective optimal search to find scheme with minimum purchase maximum sold suppliers. The experimental demonstration based on platform shows that when number participants no more than 10, delay time 0.2 s, fluctuates at 200,000 yuan, which better other comparison methods.
