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 Tariff Design Study
Objective
Evaluation of grid tariff design for homes
Estimate the financial impact of a change in tariff
Methodology
Simulate homes with fixed and time-of-use (TOU) tariff
Compute and compare electricity costs at the end of a period
Approach
Use GridLAB-D to model a fixed and TOU simplified IEEE 4 (single home) and IEEE 13 (73 homes) node feeders.
Evaluate the impact of switching to TOU tariff on electricity costs

3. Tariff Design Template
Location: San Jose CA
Day: Winter peak
Weather: TMY3
Base case: Fixed tariff
Study cases: TOU tariff with off-peak tariff as a fraction of peak tariff
Objective: Find a revenue neutral TOU tariff

4. Methodology GridLAB-D Version: 4.2.0-190828
Model structure: 1 home + 1 meter + feeder (IEEE 4)
73 homes + 73 residential meters + feeder (IEEE 13)
Residential model: ETP
Implicit end-use load shapes: EIA 2015
Simulation timestep: 1 hour

14. First Run!

15. Success!

16. Look at and download the output (Artifacts)

17. Results : bill_sum.csv The output contains ... Model name Tariff type
Total amount of money billed for the simulation period
Standard deviation between houses (Note, IEEE 4 model contains only one house, therefore the standard deviation is not available)

18. Customizing your simulation
Back to GitHub...

19. Locate the fork of `tariff_design` repository

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

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

23. ‘simulation_configuration.csv`
Model name:
IEEE 4 (1 house + 1 meter + 1 feeder)
IEEE 13 (73 houses + 73 meters + 1 feeder)
Weather file
All available locations can be found in ‘data/’ folder
Start and stop time and timezone of the simulation
Bill dump time
Specifies when the bill sum per house should be recorded
Sums all the monthly bills together until the billdump time

24. ‘simulation_configuration.csv`
Tariff
Fixed : summer and winter
TOU : summer and winter
Specify the off-peak price and a multiplier that calculates the peak price
Peak start and end hours determine the duty cycle of the tariff
