基于PVsyst的既有建筑光伏一体化系统仿真与优化

Simulation and Optimization of Photovoltaic Integrated System for Existing Buildings based on PVsyst

目前,我国现有建筑数量十分庞大,为降低既有建筑的能耗,可在建筑表面敷设太阳能光伏板,为建筑提供照明以及办公等用电需求。以吉林建筑科技学院科研楼为研究对象,利用PVsyst软件对既有建筑的光伏一体化系统进行仿真研究,分析得出系统在4—8月份发电量较高。系统内太阳入射角度修正系数和光伏组件的运行温度造成的损失分别为2.8%和3.7%,可以通过改变光伏组件倾角和改善光伏组件的运行环境来减小上述损失。综上所述,利用PVsyst软件对光伏建筑一体化系统进行模拟,分析系统的各项损失,并提出优化方法是可行的。

At present,the number of existing buildings in China is very large.In order to reduce the energy consumption of existing buildings,solar photovoltaic panels can be laid on the surface of buildings to provide lighting and office electricity demand for buildings.Taking the research building of Jilin University of Architecture and Technology as the research object,the PVsyst software is used to conduct simulation research on the integrated photovoltaic system of the existing building,and the analysis shows that the system has a high power generation from April to August.In the system,the solar incident Angle correction coefficient and the operating temperature of photovoltaic modules cause losses of 2.8%and 3.7%,respectively.These losses can be reduced by changing the angle of photovoltaic modules and improving the operating environment of photovoltaic modules.To sum up,it is feasible to use PVsyst software to simulate the integrated photovoltaic building system,analyze the losses of the system,and put forward the optimization method.
