Photovoltaic Nowcasting with Bi-level Spatio-temporal Analysis Incorporating Sky Images
IEEE Transactions on Sustainable Energy（2021）
摘要
Today many large-scale photovoltaic (PV) plants have been equipped with sky imaging systems. The sky images contain abundant spatio-temporal information of the local climate condition at the PV plant. Meanwhile, power outputs of the PV systems located at different sites in a certain geographical area also exhibit spatio-temporal correlation. It is of interest to improve the accuracy of PV nowcasti...
