IV Curves from 6-yr old modules New Project 2012
Fast Transient Studies Project started 2011
AC power has 80% dropouts in 5 seconds.DC current (not V) fluctuates.
10/24/2011, Cronin gave a seminar at the ACC on “How much Energy Storage will we need?” using data on fluctuations.
Motivates better forecasting.
30 hour in advance WRF forecastsare impressive over large scales.
But validation with PV data showsa need for better cloud forecasts
GHI forecast (-30 hrs) DNI forecast (-30 hrs) Satellite image (0 hrs)
Forecasting Cloud Events New Project 2012
Cloud camera frameand video analysis toestimate cloud velocities.
Cloud arrival time can bepredicted 10 minutes in advance.
This provides an early warning for power plant outages.
