Two-Stages Bidding Strategies for Residential Microgrids Based Peer-to-Peer Energy Trading

With the promoting of residential Microgrids and transactive energy system, peer-to-peer (P2P) energy transactive mechanism among small household entities have emerged, which allows residents to actively trade energy with their neighbors has appeared in the residential Microgrid. In order to ensure the success of this trading mode, designing an effective bidding strategy in the P2P energy trading has been a hot topic in recent studies. However, in current studies, limitation still exsited such as lack of flexibility and unfair constraints on trading. To solve these problems, this paper proposes a two-stage bidding strategy in the residential Microgrid. In this mechanism, the equilibrim among fair competition in market, economic benefits in participants, and self-sufficiency in Mircogird is achieved. Besides, aiming to help residents make better decisions about their through bidding process, a trading price predictor and a tool for risk analysis, “Value at Risk” (VaR) are also offered in this process. Moreover, case studies with multiple households involved in a residential Microgrid verifed the effectiveness of the proposed method.
