摘　　要：在高比例可再生能源渗透率的综合能源系统中,仅以保障源荷平衡为目标的调度策略是缺乏弹性的。因此提出了一种含相变墙体的综合能源系统方案以及一个详细分析用户建筑的热力学模型,来改善源–荷间的匹配程度,进而实现综合能源系统的灵活性与经济性。通过Dymola与Matlab联合搭建含相变墙体建筑的综合能源系统。从墙体结构、室温设定模式、抵御故障及故障恢复3个角度分析相变墙体热惯性对综合能源系统的影响。模拟结果证明了所提出的含相变墙体的综合系统的优越性和其调度策略的有效性。In the high proportion of renewable energy penetration integrated energy system,it is inelastic to have the scheduling strategy only ensuring the balance of source and load.Therefore,this paper proposes an integrated energy system scheme with the phase change wall and a thermodynamic model for detailed analysis of the user buildings to improve the matching degree between source and load and realize the flexibility and economy of the integrated energy system.The Dymola and the Matlab are jointly used to build an integrated energy system for buildings with the phase change walls.The influence of thermal inertia of the phase change wall on the integrated energy system is analyzed from three aspects:the wall structure,the room temperature setting mode,and the fault resistance and fault recovery.The simulation results prove the superiority of the proposed integrated system with the phase change walls and the effectiveness of its scheduling strategy.
