Research and Design on Household Distributed Grid-Connected Photovoltaic Power Generation System

家用分布式光伏并网发电系统是发展可再生能源的关键因素,为对其进行有效控制,研究了德国劳特林根地区独栋家庭住户的光伏发电系统的最佳选型方案,首先,通过VDI4655得到独栋家庭住户的电能需求量,然后,设计了家用分布式光伏并网发电系统的各项参数和组件选型,选择AD180M6-Ak单晶硅光伏电池板,以四行七列的串并联方式连接,并且选择功率为2.0k Wh、电容范围为(120~335)V的Galvo 2.0-1/240单相逆变器,最后针对德国劳特林根地区的太阳辐射量和基本的天文参数,使用PVsyst软件进行仿真模拟,确定最佳倾斜角和方位角,得到完善的光伏系统,进行了性能分析。其中,年供电量为5620.9kWh/年,可满足家庭用户80.3%的电能需求。

Household distributed grid-connected photovoltaic power generation system is a key factor for the development of renewable energy. In order to effective control, we researched on the single-family household PV system to choose the best design in Reutlingen, Germany. Firstly, according to VDI4655, the energy demand of single family house was acquired, and the parameters and models of household distributed grid-connected photovoltaic power generation system were designed, the AD180M6-Ak monocrystalline silicon photovoltaic panels which were four rows of seven columns series parallel connected were selected. Also, the Galvo 2.0-1/240 single-phase inverters which were 2.0kWh power and （120-335）V capacitance were selected. Finally, based on solar radiation and some basic astronomical parameters in Reutlingen, we used PVsyst software to simulate and determine the optimum tilt angle and azimuth. We acquired the complete system and analyzed include that the generation was 5620.9kWh/year and could satisfy 80.3% electricity energy demand.
