Abstract:The increasing penetration of distributed energy resources (DERs) in distribution systems calls for a new market platform to better manage and utilize flexible resources of heterogeneous owners in a community microgrid. This paper proposes an energy trading market that enables peer-to-peer (P2P) energy trading among multiple prosumers, in which consumers broadcast their demand requests and resource owners send out offers for identity verification and approval. Moreover, an unbalanced power flow based safety check problem is used to ensure that the proposed market design complies with all physical constraints of the distribution network. Finally, a modified IEEE 34-bus system is used to evaluate the effectiveness and validity of the proposed trading market design.
