虚拟储能的光伏建筑一体化微网优化控制研究

Research on BIPV Microgrid Optimization Control with Virtual Energy Storage

以办公楼为研究对象,建立引入蓄温虚拟储能后的光伏一体化建筑能源调度模型。对光伏建筑中的光伏单元、蓄电池、空调设备、电热水器的组成单元模型进行特性分析,建立了空调设备、电热水器的蓄能储能引入后的微网能源调度模型。利用DEST软件对办公楼的能耗数据进行仿真计算,在夏季降温场景中对没有引入虚拟储能工况、单独引入空调设备或电热水器的蓄能储能工况、同时引入两种虚拟储能的工况进行了分析和计算。结果表明在引入虚拟储能之后的微网能够有效的调度和节约能源,使得建筑能耗进一步降低。

Taking an office building as the research object,an energy dispatch model of photovoltaic integrated building is established based on virtual heat storage,and the characteristics of unit model composed in BIPV are analyzed,including photovoltaic units,storage batteries,air conditioning equipment,electric water heaters.A microgrid energy dispatch model is established after the introduction of energy storage for air conditioning equipment and electric water heaters.The DEST software is used to simulate the energy consumption data of the office building.In the summer cooling scenario,three energy storage conditions such as without introducing virtual energy storage,introducing one virtual energy of either air conditioning equipment or electric water heater,and with the introduction of two types of virtual energy are analyzed and calculated respectively.The results show that the microgrid with the introduction of virtual energy storage can effectively schedule and reduce energy consumption,which further reduces building energy consumption.
