摘要：

The energy transaction among prosumers is of great significance to promote the local consumption of distributed resources. To this end, by fully considering the interests of prosumers, a complete peer-to-peer transaction mechanism for prosumers without coordination entities is proposed to maximize the social welfare. Taking the microgrid as an example, the internal resources of prosumers are modeled, and the physical network constraints are introduced to propose the centralized optimal model for energy transaction of multiple prosumers. Through the branch tearing method and Lagrangian dual decomposition, the problem is transformed into a distributed optimization problem and solved by the alternating direction method of multipliers. It can be proven that this mechanism requires no coordination of third-party entities, and only needs to transmit information between interacting entities. The optimization can be completed through the resource allocation within each entity to achieve the fully-distributed solution. In addition, the price conforms to the operation law of the actual market better. Finally, four microgrids are taken as an example for case anlysis to verify the reliability and effectiveness of the proposed transaction mechanism. © 2023 Automation of Electric Power Systems Press.
