The intermittency of solar energy produces instabilities in power grids. These instabilities are reduced with an intrahour solar forecast that uses ground-based sky imaging systems. Sky imaging systems use lenses to acquire images concentrating light beams in a sensor. The light beams received by the sky imager have an elevation angle with respect to the device’s normal. Thus, the pixels in the image contain information from different areas of the sky within the imaging system field of view…
