Research on Multi-agents Distributed Transactions in Distribution Network Based on ADMM

Aiming at the electricity transactions between prosumers in the distribution network level, a multi-agent peer-to-peer (P2P) transaction algorithm in the distribution system is proposed. In order to fully protect the privacy and security of each agent, this paper firstly builds a P2P transaction model between prosumers. At the same time, this model takes the need to collect grid usage prices into account and further the alternating direction method of multipliers (ADMM) is used to decompose the model in order to realize distributed transactions. Different numbers of prosumers and grid usage prices are selected as test cases. The results verify the convergence speed of the model, and the model can fully protect the privacy of prosumers.
