SCRIPT - Smart ChaRging Infrastructure Planning Tool

This repository comprises two parts:

  1. Information about the journal paper "Large Scale Scenarios of Electric Vehicle Charging with a Data-Driven Model of Control", and
  2. Code to run the tool itself.

This project was funded by the California Energy Commission under grant EPC-16-057.

Principal Investigator: Gustavo Vianna Cezar.

SLAC National Accelerator Laboratory is operated for the US Department of Energy by Stanford University under Contract DE-AC02-76SF00515.

Paper

Powell, S., Cezar, G. V., Apostolaki-Iosifidou, E., & Rajagopal, R. (2021). "Large Scale Scenarios of Electric Vehicle Charging with a Data-Driven Model of Control." Under review.

Summary

Long-term planning for transportation electrification demands large-scale, detailed, data-driven scenarios for future charging demand. Controlled charging is a powerful and growing tool for managing the impact of charging on the grid; it is critical to include in planning scenarios.

Many scenario tools today, however, are expensive to scale and cannot represent complex load controls. In this paper and tool we address that gap. We present a scalable tool for scenario generation based in real data from the California Bay Area, and we present a novel methodology to model the impact of load management control on aggregate charging profiles using machine learning.

Model Objects

Core to our methodology is the separation of model training from scenario generation. The tool below does not reference the raw data directly but uses pre-trained model objects. To make those easy to access by the research community, we have made the model objects available for download here:

Paper Code

The paper highlights rate design as an application for this tool using the following procedure:

  1. Generate data using the sessions model
  2. Define a custom rate schedule to study
  3. Build training data for that rate schedule and learn its mapping
  4. Apply the mapping within the model to study its impact on a large-scale scenario. Code for that application is included here in the folder PaperCode/CustomRate

The main model code is also embedded and used in the tool below to generate new scenarios. Further code associated with the paper is available on request.

Getting Started with SCRIPT Running Locally

install postgres first to avoid headaches

$ brew install postgresql

to start the DB server you can just:

$ brew services start postgresql

to create the DB

$ createdb scriptdb
To connect to the DB - I used TablePlus. Connection params for development are the postgres defaults. You can also check the settings file to find them: webserver/app/settings/base.py. For now just save the new connection - we will connect to it once the Django Server is running

Creating the env - ensure you are running the anaconda 4.5.x +

$ conda env create -f environment.yml

Updating the env with latest

$ conda env update -f environment.yml

Updating the environment.yml file after adding new packages locally

$ conda env export --name venv_script > environment.yml

Starting the env

$ conda activate venv_script

Stopping the env

$ conda deactivate

Migrate the DB

$ cd webserver
$ python manage.py migrate --settings=app.settings.base

Upload County Data (this part will take about 15 minutes)

$ cd UploadToCounty
$ python UploadToPostgresCountiesZips.py

Ensure that node version is loaded and consistent with the .nvmrc file

$ cd frontend
$ nvm use

Install JS dependencies (make sure npm is installed)

$ cd frontend
$ yarn install

Running The App (make sure venv_script env is active on all the below terminals)

Run Django server (terminal 1)

$ cd webserver
$ python manage.py runserver --settings=app.settings.base

Run Redis in another tab (terminal 2)

$ cd webserver
$ redis-server

Run celery in another tab (terminal 3)

$ cd webserver
$ celery -A app worker --loglevel=INFO

Run flower in another tab (terminal 4)

$ cd webserver
$ flower -A app --port=5555

Start JS server (terminal 5)

$ cd frontend
$ yarn start

Note: Make sure your aws credentials are configured in your local machine

Note: If you run into errors when getting started, attempting to install dependencies individually might lead to breakage due to inconsistencies in versioning. Your best option would be to remove conda env and recreate it with the existing environment.yml file. Further make sure the node version being used matches with the .nvmrc file.
