Abstract: The present invention is concerned with the operation of solar power plants such as Photo Voltaic (PV) or Concentrated Solar thermal Power (CSP) plants. The invention involves recursive updating of estimated parameters pertaining to pre-defined and physically motivated cloud evolution models that are instantiated and assigned to clouds identified in images taken by a ground-based visible-light camera. Identification of clouds, which includes assigning individual pixels of an image to one or several identified clouds, and selection of matching cloud models invoke some elaborate complexity beyond conventional pixel-wise image processing. This ultimately allows to predict a cloud-wise, as opposed to a pixel-wise, evolution based on cloud evolution models with a limited number of estimated parameters.
