随着太阳能发电量的增加，在配电网规划和运行中必须考虑这一发电量的建模。本文的目的是提出一个模型，可以估计每小时的能量产生的太阳能电池组件在不同的日照条件。太阳能组件的输出功率主要取决于太阳辐射、太阳能电池的温度和组件的技术性能。其中最复杂的是太阳辐射及其在真实的天空和天气条件下的变化。为了模拟芬兰南部地区的太阳辐射，从芬兰气象研究所获得了每小时测量的长期辐射和日照数据。利用这些数据，构建了太阳辐射的回归模型，并用于发电模型。太阳辐射模型能够很好地估计辐射，特别是对于水平表面。
With the increase of solar power production, the modelling of this generation has to be considered in distribution network planning and operation. The purpose of this paper is to present a model that can estimate the hourly energy produced by a solar module in different sunshine conditions. The output power of a solar module is mainly dependent on solar radiation, temperature of the solar cell, and the technical properties of the module. The most complex of these is the solar radiation and how it changes in real sky and weather conditions. To model the solar radiation in southern Finland area, measured hourly long term radiation and sunshine data was obtained from the Finnish Meteorological Institution. With these data a regression model for solar irradiation was constructed and used for the power generation model. The solar irradiation model manages to estimate the irradiation quite well especially for a horizontal surface.
