Satellite remote sensing models (above left), numerical weather
prediction (above center), and ground sensors (above right) are used to
provide solar forecasts for time horizons from 10 minutes to 72 hours.
The map on the top left shows GOES satellite GHI [W/m2] for
the San Diego area at 1 km resolution. Clouds (east half) cause a
substantial reduction in GHI. The coast is visible due to satellite
navigation errors. Cloud motion vectors are applied to forecast the
movement of the clouds. North American Model (NAM) output from the
National Weather Service is shown on the bottom left for a storm system
moving through California.
At the UCSD campus advanced sky imager technology is applied to get a
fine-grained picture of local clouds.
images of the La Jolla skies produce solar output forecasts for
1 MW of dispersed solar PV that will be utilized by a microgrid
scheduler/optimizer to enable supply, storage and load adjustments based
on dynamic market price signals (below right).
