摘要
光伏电池输出功率受温度和光强影响,且影响程度具有非线性特征。采用建立二维表的方式来预测光伏电池最大输出功率。该方法将预测功率转化为预测温度和光强,并根据温度和光强预测结果查表得到光伏电池最大输出功率。算例表明,文中所提出的方法能够较为准确地预测光伏电池最大输出功率。
The output power of photovohaic cells is heavily affected by temperature and illumination intensity and the influence is characteristic of non-linearity. In order to forecast the maximum output power of photovohaic cells. This paper presents a method using a two-dimensional table to calculate the maximum output power df photovoltaic cells. The forecasting of output power can be replaced by the forecasting of temperature and illumination intensity in this method. According to the forecasting result of temperature and illumination intensity, the maximum output power of photovohaic cells can be got through two-dimensional table. The example shows that the maximum output power of photovohaic cells can be calculated accurately by this method provided.
