摘　　要：从用户角度出发,提出一种考虑建筑物热惯性的综合能源系统主从博弈协调优化策略。首先,建立热网特性模型和建筑物热惯性模型,并构建以微网运营商为领导者,用户为跟随者的主从博弈数学模型。在光伏出力大时,用户通过电制热设备将电能转化为热能,并利用建筑物热惯性将热能加以存储,无需将光伏余电尽数售给微网运营商,可增强用户权益,同时可有效避免大量光伏余电接入电网,进而缓和余电上网的压力。其次,考虑用户用能满意度及温度舒适度,建立微网运营商与用户的定价、定量模型,并证明Stackelberg博弈均衡解的存在性与唯一性。最后通过算例验证所提策略的有效性,极大地增强了用户权益,同时避免用户光伏余电大量接入电网。The paper proposes a coordinated optimization strategy of Stackelberg game for integrated energy systems considering the thermal inertia of buildings from the users'perspective.First,the heat network characteristics model and the thermal inertia model of buildings are established,and the mathematical model of the Stackelberg game with the microgrid operator as the leader and the users as the follower is constructed.When the photovoltaic output is high,users convert electricity into heat through electric heating equipment and store the heat energy by using the thermal inertia of buildings,so that they do not need to sell all the surplus photovoltaic power to the microgrid operator,which enhances the rights and interests of users and effectively avoids a large amount of surplus photovoltaic power to be connected to the grid and relieves pressure on surplus power to connect to the grid.Secondly,the pricing and quantitative model between the microgrid operator and the users is established,and the existence and uniqueness of the Stackelberg equilibrium solution are proved,taking into account the users'satisfaction with energy use and temperature comfort.Finally,the effectiveness of the proposed strategy is verified by an practical example,which greatly enhances users'rights and interests while avoiding a large amount of surplus photovoltaic power from users to connect to the external grid.
