摘　　要：针对当前分布式交易市场未充分考虑终端用户用能特性,且市场主体之间的博弈关系仍需进一步挖掘等问题,文中提出了考虑智能建筑特性的多微网端对端(P2P)能量交易方法。首先,以智能建筑作为终端负荷载体,提出了一种新的建筑热阻-热容热平衡模型,并构建了市场主体即微网的自治调度模型。其次,分别采用非合作博弈及主从博弈模型分析了P2P交易过程中卖方之间以及卖方与买方之间的博弈关系,完善了对P2P交易各环节博弈关系的分析。最后,通过构建实际算例,分析了终端用能特性对微网经济调度及P2P交易的影响,同时结合具体指标量化分析了P2P交易对微网运行带来的经济与技术效益,并分析了P2P交易对配电系统运行产生的影响。Aiming at the problems that the current distributed trading market does not fully consider the energy consumption characteristics of end users, and the game relationship between market entities still needs to be further explored, this paper proposes a peer-to-peer(P2P) trading method of multiple microgrids considering the characteristics of smart buildings. Firstly,taking smart buildings as the end load carrier, this paper proposes a new building resistance-capacity(R-C) thermal balance model and constructs an autonomous scheduling model for the market entities, i.e., the microgrids. Secondly, the non-cooperative game model and the Stackelberg game model are used to analyze the game relationship among sellers and the game relationship between sellers and buyers in the P2P transaction process, which improves the analysis of the game relationship between the links in the P2P transaction. Finally, through the practical cases, the influence of end energy consumption characteristics on the microgrid economic scheduling and P2P transactions is analyzed, and the economic and technical benefits of P2P transactions on the operation of microgrids are quantitatively analyzed by using specific indices. The influence of P2P transactions on distribution network operation is also analyzed.
