PortabLe infrastrUcture for Grid modeling

To use plug you'll need to have docker installed - visit their website for details.

If you want to run simulations using the Gurobi solver (recommended), you'll need a license file called gurobi.lic located at plug/gurobi_license/gurobi.lic

NOTE: certain license types are not supported at the moment.

We describe the workflow for running a standalone installation on a single computer. To get started, run cd standalone in your shell, followed by docker-compose up (optionally pass -d to run in the background). The docker images will be downloaded automatically from our container registry.

The client container contains both PowerSimData and PostREISE packages, for scenario management and analysis, respectively. The default compose file starts the client running bash, which serves as an entrypoint to either an ipython shell:

docker-compose exec client ipython

or a jupyter notebook:

docker-compose exec client jupyter lab --port=10000 --no-browser --ip=0.0.0.0 --allow-root

See the PowerSimData tutorial for details about how to run a simulation, or try the commands in demo_*.py for a simple example.

The usage within the containerized setup is almost identical to what is presented in the PowerSimData repo, but there are some small differences.

1. When calling scenario.launch_simulation(), the process is launched via http rather than ssh, and we provide a container specific way to query the status. This can be done using scenario.check_progress() which will return some output in the following form.

{'errors': [],
 'output': ['Validation complete!',
  'Launching scenario with parameters:',
  "{'interval': 24, 'n_interval': 2, 'start_index': 5113, 'input_dir': '/mnt/bes/pcm/tmp/scenario_1', 'execute_dir': '/mnt/bes/pcm/tmp/scenario_1/output', 'threads': None}"],
 'scenario_id': 1,
 'status': 'running'}

Note that the errors/output fields correspond to lines of stderr/stdout, respectively.

2. Once the simulation is complete, the results are extracted automatically, so there is no need to call scenario.extract_simulation_output() (although doing so will simply print a warning). The data can be accessed from the Analyze state within the container, but if you have a use case that is not yet supported, the data can be detached from docker, which we describe below.

Currently, the simplest way to access simulation output is by copying the results from the container. To copy the full volume as-is, use the following:

docker cp client:/mnt/bes/pcm DEST_FOLDER

Optionally, to snapshot the results to a tar archive, run

docker cp client:/mnt/bes/pcm - > FILENAME.tar

If you want to build any of the docker images locally you should use the following directory structure so relative paths will work.

    .
    ├── plug
    └── REISE.jl

Then, to build the images when starting, use the override feature described here, for example

docker-compose -f docker-compose.yml -f docker-compose.dev.yml up --build

The contents of the scenario_framework folder are provided to mirror the client server architecture used internally and enable reproducible testing in that environment. Note: this is not currently recommended for general research purposes, however developers who wish to run integration tests without access to the server may find this useful.

The basic operation is similar to standalone mode described earlier. First cd to the scenario_framework directory, which has the compose file for this environment. The integration tests can be run using the following:

docker-compose up -d
docker exec scenario_client bash -c 'pytest -m "not db"'

In addition to the test suite from PowerSimData, this will run the tests provided here, which demonstrate typical user workflows.
