GridLAB-D Workshop: Electrification 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

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

Electrification study customizable parameters Location: San Jose CA Day: Winter peak (Jan 20) Weather: TMY3 Base case: 40% electric heat, hotwater, cooking, drying Study cases: 50%, 60%, 70%, 80%, 90% and 100% electrification of all enduses Objective: Impact of the feeder load

Methodology GridLAB-D Version: 4.2.0-190828 Model structure: 99 homes + 99 residential meters + feeder Residential model: ETP Enduse loadshapes: EIA 2015 Home thermal integrity 100% electric: Good Gas enduses: Above normal Electrified enduses: Very good Simulation timestep: Variable

Home Thermal Integrity Normal Above normal Good Very good Roof R-value 30 48 Wall R-value 11 19 22 Floor R-value Door R-value 3 5 Window R-value 1.7 2.1 3.2 Ventilation rate 1.0 0.5

Customizing your simulation Back to GitHub...

Locate the fork of `electrification_study` repository

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

3. Edit the ‘simulation_configuration.csv’ file

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

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

Troubleshooting

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

Go to your forked repository

Review changes

Check that the updates appear in the code

This will trigger another CircleCI build

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