This presentation was prepared with funding from the California Energy Commission under grant EPC SLAC National Accelerator Laboratory is operated for the US Department of Energy by Stanford University under Contract No. DE-AC02-76SF00515

2. California Electrification Study
Objective
Estimate feeder loading impact
Methodology
Simulate homes before and after upgrades
Compute feeder load before and after upgrades
Approach
Use GridLAB-D to model a simplified 1MW feeder with 99 homes
Evaluate impacts at various levels of electrification

3. Electrification study customizable parameters

8. Getting started with electrification study

9. Fork the repository

10. If already signed in...

12. First Run!

14. Check on the progress...

15. Success!

16. Look at and download the output (Artifacts)

17. Output plots
Raw data

18. Time series plots of substation feeder

19. Percent electrification vs Max power on substation feeder

20. Customizing your simulation
Back to GitHub...

21. Locate the fork of `electrification_study` repository

22. 2. Find the configuration file: config/simulation_configuration.csv

24. 3. Edit the ‘simulation_configuration.csv’ file

25. simulation_configuration.csv Total Number of Houses per Phase
3 phase circuit (total houses simulated = 3x total number of houses per phase)
Start and Stop time of the simulation
Weather file
All available locations can be found in “data/” folder

26. simulation_configuration.csv Simulation runs:
Define the baseline electrification. The additional runs will use the baseline value to calculate the number of homes upgrades versus vintage.
Once baseline is defined, list the run names and percent of homes of total number of houses per phase that are electric
Model name is customizable (Except for “Baseline Run”)
Number of runs can be reduced and increased by removal or addition of “Run” Lines

27. Commit the change Edit directly in this window Describe the change
Clicking commit will trigger simulation in CircleCI

28. Check the progress of the new simulation (circleci.com)

29. Troubleshooting

30. Updating your fork with changes made to aivanova5/electrification_study
If patches have been issued to the model they will appear in the original source (aivanova5/electrification_study)
To absorb those changes, the source code has to be sync’d with your fork

31. Go to your forked repository

35. Review changes

36. Check that the updates appear in the code

37. This will trigger another CircleCI build

39. If there was a problem with CircleCI Run
You can trigger another build with the same configuration by re-building from within CircleCI
