A Consideration on Relationship between the Correlation Coefficient and the Distance of Separation based on Multipoint Monitored Solar Irradiation Data in Several km² Area

Abstract

In order to evaluate the influence of intensively-installed PV systems on local distribution networks, this letter analyses the spatial correlation characteristics based on multipoint monitored solar irradiation data. As the results, a certain trend of correlation coefficient depending on a distance of separation can be obtained using the solar irradiation data for a month.
