Abstract

The main purpose of this article is to evaluate how accurate the solar energy forecasting software works, taking as references the measurements of energy levels recorded in different locations. The novelty of the article consists in evaluating the software delivery results according to the settings of the parameter simulation: time steps, integrations methods, losses due to deviation from standard solar spectrum, diffuse irradiation models, irradiation models on the inclined plane and others. The analytical investigations are carried out with the help of two EU certified software (PV-SOL and PV-GIS) dedicated to the solar forecast [1]. The experimental investigations, used for validation, are carried out at two different sites (West- and East-EU) on similar on-grid power conversion circuits. In detail, the behavior of both solar energy production systems is analyzed, by counting the amounts of generated energy over various sampling periods (day, month, year). Based on the mentioned comparison, conclusions regarding the parameter sensitivity and improvement of the estimated energy are drawn.

太阳能评估软件工具的准确性和收敛性分析

本文的主要目的是评估太阳能预报软件的准确性，以不同地点记录的能量水平作为参考。本文的新颖之处在于根据参数模拟的设置来评估软件交付结果:时间步长、积分方法、偏离标准太阳光谱的损失、漫射辐射模型、斜面上的辐射模型等。分析调查是在两个欧盟认证的软件(PV-SOL和PV-GIS)的帮助下进行的，这些软件专门用于太阳预报[1]。用于验证的实验调查是在两个不同的地点(西欧和东欧)在类似的并网电源转换电路上进行的。详细地说，通过计算不同采样周期(日、月、年)产生的能量，分析了两个太阳能生产系统的行为。基于上述比较，得出了参数灵敏度和估计能量改进的结论。
