光伏电站发电量模型预测与提升策略研究

Research on the Prediction and Improvement Strategy of Photovoltaic Power Plant Generation Model

我国光伏发电的发展主要以“集中开发,高压并网,远距离送出”的电力输出模式为主,但是在生产活动中,太阳能辐射本身具有较大的不确定性,因此需要准确把控光伏电站发电量的影响因素及太阳能板的位置情况。文章综述了影响光伏电站发电量的因素,明确了光伏电站发电量模型的预测方法及提升策略,最后以实际的模拟案例为例,开展光伏电站光伏板的位置分析。结果表明,西安地区的太阳能光伏板最优水平角为56.68°,最优方位角为–3.87°。

The development of photovoltaic power generation in China is mainly based on the power output mode of"centralized development,high voltage grid-connected,long-distance transmission",but in the production activities,the solar radiation itself has a large uncertainty,so it is necessary to accurately control the factors affecting the power generation of photovoltaic power stations and the location of solar panels.This paper summarizes the factors that affect the power generation of photovoltaic power stations,defines the prediction method and improvement strategy of the power generation model of photovoltaic power stations,and finally carries out the location analysis of photovoltaic panels of photovoltaic power stations with actual simulation cases.The results show that the optimal horizontal Angle and azimuth of solar photovoltaic panels in Xi'an area are 56.68°and–3.87°.
