A Peer-to-Peer Transaction Method for Clean Energy Considering Dynamic Network Fees and Safe Power Supply Capability

With the development of clean energy including hydropower, photovoltaics, pumped storage power stations, etc., various power generation entities participate in the sale of electricity in the distribution network. Also, users are gradually diversified, forming a multi-buyer and multi-seller trading market. However, designing the network fee to support the grid recovery costs and a reasonable transaction model is a critical issue. This article discusses a peer-to-peer transaction method that considers dynamic network fees and safe power supply capability. First, a dynamic network fee model based on the power transmission distribution factor is established. Furthermore, proposing two continuous double auctions multi-round transaction mechanisms considering the dynamic network fee are proposed. The mechanism includes a real-time rolling network verification method and real-time calculation of safe power supply capability, as well as an update strategy based on the improved disappointment-regret avoidance theory. Finally, through data simulation, multilateral bidding transactions considering dynamic network fees can be effectively realized.
