摘　　要：以光储直柔建筑系统为对象,采用模块化建模方法,建立了包含暖通系统、光伏发电系统、储能系统、电动汽车充电桩等子系统的整体仿真模型。根据室内外实时温差、系统实时取用电情况及各子系统供需优先级自动调节各子系统取用电功率,提出光储直柔建筑运行策略,并从用电灵活性、运行经济性、用能清洁性、系统稳定性等方面开展对比分析研究。仿真结果表明光储直柔建筑在保证人体热舒适性的基础上实现了光伏电力的有效消纳与“源荷双向互动”,降低了用户用能成本,提高了系统的用能清洁性和运行稳定性。This paper,with the Photovoltaics,Energy Storage,Direct Current and Flexibility(PEDF)building energy system as the object,and using the modular modeling method,established an overall simulation model involving HVAC(Heating,Ventilation,Air-conditioning,and Cooling)system,photovoltaic power generation system,energy storage system,electric vehicle charging pile and other subsystems.According to the real-time indoor and outdoor temperature difference,the real-time power generation and consumption of each subsystem,and the supply and demand priority of each subsystem,the power generation and consumption of each subsystem can be automatically adjusted.Based on this,an operation strategy for PEDF building was proposed,and comparative analysis and research were done from the aspects of electricity flexibility,operating economy,energy cleanliness,and system stability.The simulation results show that the PEDF building realizes the effective consumption of photovoltaics and"two-way interaction between source and load"while ensuring the thermal comfort of the human body,reduces the energy consumption costs,and improves the energy cleanliness and operation stability of building system.
