Solar Irradiation High Frequency Simulation Model

This paper presents a high-resolution solar radiation model essential for modern power systems with significant renewable energy integration. Given the unavailability or low temporal resolution of site-specific measurements, the model simulates high-resolution solar irradiation data necessary for planning and analysis. The model employs statistical methods, particularly Beta distributions, to generate realistic one-minute resolution solar irradiation time series, preserving both the probability density and autocorrelation structure of the measured data. Validation shows that the simulated data closely match the statistical properties of the actual measurements, providing a practical tool for scenarios where high-resolution solar data are scarce.
