Description

Sandia National Laboratories has developed a modeling approach to simulate time-synchronized, 1-minute power output form large PV plants in locations where only hourly irradiance measurements are available via satellite sources. The approach uses 1-min irradiance measurements from analogue sites in a similar geographic area. PV output data sets generated for 2007 in southern Nevada are being used for a Solar PV Grid Integration Study o estimate the integration costs associated with various utility-scale PV generation levels. Plant designs considered include both fixed-tilt thin-film, and single-axis-tracked polycrystalline Si systems ranging in size from 5 to 300 MWac. Simulated power output profiles at 1-min intervals were generated for five scenarios (149.5 MW, 222MW, 292 MW, 492 MW, and 892 MW) each comprising as many as 10 geographically separated PV plants.
