Abstract: As the prosumer group with distributed resources becomes a prominent player in the power market, and the ratio of distributed power access is increasing, the question of how to effectively utilize these resources beyond meeting the self-sufficiency of the prosumer group has become crucial. This paper begins by analyzing the current state of distributed power development. It then proposes a distributed trading framework for the prosumer group. Within this framework, a model for the prosumer group is established taking into account its real situation, and a power trading method featuring two stages, namely day-ahead and real-time, is proposed. In the day-ahead stage, the alternating direction method of multipliers（ADMM） facilitates electricity trading for the prosumer group. The transaction price is updated through the Lagrange multiplier, which iteratively adjusts according to the power supply and demand relationship. This approach not only addresses the bargaining issue of the prosumer group but also enhances the utilization of renewable resources. Concerning the real-time stage, the prosumer group is enabled to bid reasonably in power auctions based on the generalized second-price（GSP） auction rule. This resolves problems such as the susceptibility of photovoltaic power generation to weather conditions and the power deviation caused by inaccurate load forecast. Additionally, it meets the time constraints for trading among multiple prosumer groups in real-time electricity trading. Finally, the effectiveness of the proposed method is validated through calculations based on examples.
