Presentation Transcript

  1. GridLAB-D Workshop: Tariff Design Study Alyona Ivanova (SLAC) CEC Advanced Simulation Program 5 September 2019 This presentation was prepared with funding from the California Energy Commission under grant EPC-17-046. 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

  5. Overview of how to run the study • Login to your GitHub account • Create your tariff design project by cloning the template project • Modify the study parameters, e.g., • Change the city • Change the study day • Change the model of preference • Change prices of comparison • Login to CircleCI • Setup your new project • Download the results • Total bill for simulation duration • Standard deviation of total bill between houses

  6. Getting started with tariff design study

  7. Repository location : aivanova5/tariff_design

  8. Fork the repository

  9. If already signed in...

  10. Add Project Another project* Set up new project here

  11. Set-up Project

  12. Scroll down to “Start Building”

  13. First Run!

  14. Success!

  15. Look at and download the output (Artifacts)

  16. 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)

  17. Customizing your simulation Back to GitHub...

  18. Locate the fork of `tariff_design` repository

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

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

  21. ‘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

  22. ‘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

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

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