Time Function for Output Power of Photovoltaic System Based on the Influence of Micro Weather Factors
A simplified method of superposition for small or new photovoltaic power stations without historical data is presented in this paper, which only need considering the current meteorological factors, without historical data.In the new method,firstly, a standard weather day without considering the meteorological factors is set.In this case, the variation of photovoltaic output in the standard weather day is studied, Furthernore, the influence of various weather factors, cloudiness haze index, is considered separately.Compared predicted values and actual values,the influence coefficient of various weather factors on the power output is calculated, and it is multiplied by the photovoltaic output in the standard weather day cumulatively.Considering local meteorological conditions and using the proposed conversion method,the output of photovoltaic generation is predicted and the predicted results are compared with the measured data.Comparison results show that the proposed method is correct and available.
