Abstract
During the last decades, photovoltaic (PV) panels have been widely installed in Japanese residential areas to achieve clean and renewable energy. This work employs DSM (Digital Surface Model) layers to extract important elevations, such as trees and buildings, in conjunction with assumptions of cloud movement processes from GIS (Geographic Information System) to obtain realistic solar power affected by solar radiation shading on the PV panel. With GIS technology, the solar radiation shading effects are combined with distribution system modeling to observe the significant impact of shadows in the overall distribution system. Moreover, this research can facilitate a more effective distribution system planning by evaluating the influence of PV power variations, assuming a large number of installations.
