Photovoltaic Power Generation Model and its Analysis Based on Photovoltaic Power Plant Output Data

Based on real-time data collected from a specific photovoltaic power plant, mathematical modeling of the electricity output of the photovoltaic power plant is facilitated by combining knowledge of optics and the basic structure of photovoltaic power plants in this paper. The model is composed of two crucial parameters: direct irradiance and environmental enhancement factor, endowing it with not only physical significance but also the capability for numerical estimation and analysis. The constructed photovoltaic power generation model is more in line with actual physical performance, and the comprehensive error between the estimated values and the measured values is only 7%. It can provide a good estimation of radiation and environmental factors.
