摘要
光伏组件的输出特性受温度、光照强度、阴影的影响,当光伏组件受到周围建筑物、树木、电线杆及天空中的乌云等阴影的影响时,会发生局部或者完全被遮蔽的现象。当发生部分遮蔽现象时,其输出功率降低,为了最大限度的提取光伏板的电流,本文提出了一种蚁群并联光伏发电系统,该系统可以大大提高光伏电池板在发生局部遮蔽现象时的发电效率。
The performance of a photovoltaic（PV） module is affected by temperature,solar insolation and shading.Often,the PV module gets shadowed,completely or partially,by the neighboring buildings and towers,trees,poles and passing clouds.Under partially shaded conditions,the PV output power is reduced.In order to extract the PV current as much as possible,this paper presents a photovoltaic power generation system in ant-colony parallel.It can greatly enhance the efficiency of PV power generation,especially when the PV module is partly shaded.
