摘要/Abstract

摘要：

点对点(peer-to-peer, P2P)交易是一种适合分布式电力产消者参与电力市场的新型交易方式。基于市场化视角并综合考虑产消者的经济效益和分布式清洁能源就地消纳情况,设计了基于双轮竞价博弈的电力P2P交易流程,建立了以经济效益为目标和以申报电量出清为目标的双轮竞价博弈模型。针对一个包含居民、办公、商业等不同类型电力产消者的社区进行算例分析,结果显示:相较于连续双边拍卖、单轮竞价博弈以及全额与电网(peer-to-grid, P2G)交易的方式,双轮竞价博弈方式下经济效益分别提升19.01%、28.78%、56.81%,分布式清洁能源就地消纳率分别提升10.51%、24.05%、85.10%。结果表明,采用合理的竞价方式和报价策略,可增加分布式电力产消者的收益,也可提高P2P交易效率,促进分布式清洁能源就地消纳,助力“双碳”目标的实现。

Abstract:

P2P transactions are a new transaction mode suitable for distributed electricity prosumers participating in the electricity market. Considering the economic benefits to prosumers and the local consumption of distributed clean energy, a P2P electricity transaction process was developed based on a double-round bidding game, and a game model with the goals of economic benefit and clearing energy was established. An example analysis was conducted for a community with different types of distributed electricity prosumers such as residents, offices, and commerce. Compared with continuous bilateral auctions, one-round bidding games, and P2G, the results of P2P transactions with a double-round bidding game showed that economic benefits increased by 19.01%, 28.78%, and 56.81%, and the local consumption rate of distributed clean energy increased by 10.51%, 24.05%, and 85.10%, respectively. In conclusion, adopting a bidding method and strategy can increase the revenue of distributed electricity prosumers, improve the efficiency of P2P transactions, promote the local consumption of distributed clean energy, and help realize the “double carbon” goal.

Key words: distributed clean energy, P2P electricity transactions, double-round bidding game, economic benefit, local consumption
