摘要:
光伏功率的不稳定因素主要由太阳辐照度波动引起,有必要对区域太阳辐照度波动特征进行分析研究,可为太阳辐照度预测和发电计划的制定提供理论基础依据。通过利用乌干达布库津杜太阳能热电混合电站2020年1月、3月、11-12月的太阳辐照度监测数据,基于MATLAB方法,对该电站的太阳辐照度波动的频次、斜率和持续时间进行分析研究,探明该地区太阳能辐照度的变化特征。结果表明,乌干达辐照度波动在旱季比雨季更频繁,下午的波动频次高于上午;非晴天高斜率波动事件多于晴天,但晴天也可能出现高斜率波动事件;乌干达大多数辐照度波动持续不到5min。
Abstract:
The instability factor of photovoltaic power is mainly caused by solar irradiance fluctuation. It is necessary to analyze and study the characteristics of regional solar irradiance fluctuation, which can provide the theoretical basis for solar irradiance prediction and power generation plan formulation. By using the solar irradiance monitoring data of the solar hybrid power Station in Bukuzindu, Uganda in January, March, and November-December 2020, the frequency, slope, and duration of solar irradiance fluctuations of the station were analyzed and studied based on the MATLAB method, and the variation characteristics of solar irradiance in this region were explored. The results showed that the frequency of irradiance fluctuations in the dry season was higher than that in the rainy season, and the fluctuation frequency was higher in the afternoon than in the morning. There were more high-slope fluctuation events on non-sunny days than on sunny days, but high-slope fluctuation events were likely to occur on sunny days. Most irradiance fluctuations in Uganda lasted less than 5 minutes.
