You have been reading about the relations between time and space, and you have read about different time horizons of interest to the solar energy and electric grid fields. Now, let us apply that knowledge to Table 8.2 from the Chapter by Coimbra, Kleissl, and Marquez (2013).
Technique | Sampling Rate | Spatial Resolution | Spatial Extent | Suitable Forecast Horizon | Application |
---|---|---|---|---|---|
Persistence | High | 1 point | 1 point | Minutes | Baseline |
Sky-Imagery | 30 sec | 10-100 m | 2-5 m radius | Tens of minutes | Short-term ramps, regulation |
GOES Satellite Data | 15 min | 1000 m | U.S.A. | 5 hours | Load following |
NAM weather model | 3600 sec | 12 km | U.S.A. | 10 days | Unit commitment |
Questions to discuss:
Please share your reflections on these questions in the Yellowdig community. I wonder if everyone will come to the same conclusions.
When you create a post in the Yellowdig discussion space, you are required to choose a topic tag. For Lesson 8 discussion, please use these tags:
Yellowdig points you earn over the weekly point earning period (from Saturday to next Friday) will count towards 1000 pts. weekly target. But you can go above it (to 1350 pts. max). Yellowdig discussions will account for 15% of the total grade in the course.
There is no hard deadline for participating in these discussions, but beware of the weekly limit. You need to create posts every week to stay on target with your total discussion participation grade. Each weekly point earning cycle ends Friday night, and a new period starts on Saturday.
