Solar Irradiance Model for Large-scale Photovoltaic Generation Considering Passing Cloud Shadow Effect
This paper proposed a model to describe solar irradiance temporal/spatial distribution considering cloud shadows for large-scale photovoltaic (PV) generation. The irradiance time series is calculated focusing on its randomness and uncertainty caused by cloud shadow movement. The irradiance reached the titled PV panel is calculated considering astronomical irradiance, atmospheric attenuation and the impact of transient cloud shadows. This model illustrates the geography impact on the sunrise and sunset time, correlation between cloud and weather type, cloud shadow model considering diversity cloud type transparency , “cloud effect”, cloud overlapping and cloud edge effect. The developed model can be used to analyze PV generation steady and transient performance, real time control and large PV plant integration impact on grid.
