摘　　要：在建筑光储直柔系统中,电量平衡关系由此前的市电、负荷二者平衡转变为市电、光伏、储能和负荷四者间的平衡,也对系统容量配置提出新的要求。首先,聚焦于光储直柔的储能系统,考虑储电和储冷两类方式,以经济性为目标对其容量和功率进行优化。然后,提出“运行优化-设计优化”的双层优化模型:在运行优化模型中,考虑充电桩、基于建筑热惯性的柔性空调系统、蓄冷设施以及储能电池等柔性设备的运行调节,基于分时电价机制以电费最低为运行目标,实现全年8760 h的供需动态平衡计算;在设计优化模型中,以运行优化模型计算出的全年电费和设备投资折旧为目标函数,采用粒子群算法实现储能系统容量和功率参数的优化配置。最后,以深圳办公建筑为案例进行储能系统的优化配置,案例分析表明电池和蓄冷设施的配置能够提升系统经济性,同时所提出的方法能够实现储能设施配置和系统能源调度的一体化设计,为光储直柔系统设计提供指导。In the building photovoltaic,energy storage,direct current and flexibility(PEDF)system,the power balance relationship is changed from the previous balance between utility and load to the balance between utility,photovoltaic,energy storage and load,which also puts forward new requirements for the system capacity allocation.Firstly,we focus on the energy storage system of PEDF,and consider two types of storage,namely,power and cooling storage,and optimize its capacity and power with the objective of economy.Then a two-layer optimization model of“operation optimization and design optimization”is proposed.In the operation optimization model,the operation regulation of flexible equipment such as electric vehicle charging piles,flexible air-conditioning system based on thermal inertia of the building,cooling storage facilities and energy storage batteries are considered,and the annual 8760 hours of equilibrium calculations are realized with the objective of minimizing the electricity cost.In the design optimization model,the particle swarm algorithm is used to achieve the optimal configuration of the capacity and power parameters of the energy storage system with the annual electricity cost and equipment investment depreciation as the objective function.Finally,this study takes Shenzhen office building as a case study for the optimal configuration of the energy storage system,and the arithmetic example shows that the configuration of the battery and the cooling storage facility can improve the system economy,while the method proposed in this study can realize the operation optimization of the multi-flexible equipment and the configuration optimization of the equipment capacity,which can provide the guidance for the design of the PEDF system.
