局域能源市场多产消者P2P交易框架设计

Design of P2P trading framework for multiple prosumers in local energy market

随着局域能源市场中分布式能源的大量接入和电力系统运行方式的逐渐转变,具有电能生产/消费行为的产消者得到了广泛关注与研究。在此背景下,为提高小规模能源在局域能源市场中的就地消纳能力,设计了一种面向局域能源市场中多产消者的点对点(P2P)日前市场交易框架。在局域能源市场建立了P2P市场交易平台,并对产消者的基本特征进行了归纳分析,提出了典型的产消者组合类型;在产消者层面,采用供给函数均衡模型对产消者竞价行为进行建模,确立了含多产消者的P2P交易平台参与局域能源市场交易;采用连续双边拍卖机制对产消者之间进行P2P匹配,并确定交易过程中的拍卖价格和交易价格。最后,通过算例验证了所提P2P交易框架的有效性。

With the massive access of distributed energy in local energy market and the gradual transformation of power system operation mode,the prosumers with electric energy production or consumption behavior have been widely concerned and studied.Under this background,in order to improve the local consumption capacity of small-scale energy in local energy market,a P2P(Peer-to-Peer)day-ahead market transaction framework is designed for multiple prosumers in local energy market.The P2P market trading platform is established in local energy market,the basic characteristics of prosumers are summarized and analyzed,and the typical combination types of prosumers are put forward.At the level of prosumers,the supply function equilibrium model is used to model the bidding behavior of prosumers,and a P2P trading platform with prosumers is established to participate in local energy market transaction.Meanwhile,the P2P matching between prosumers is carried out by continuous bilateral auction mechanism,and the auction price and transaction price in the process of transaction are determined.Finally,an example is given to verify the effectiveness of the proposed P2P trading framework.
