This is a online remote demonstration. So there's no installation required.
The tutorial has 3 parts:
- An introduction to jupyter notebooks
- A simple value exchange that sends pi (i.e. 3.14...) back and forth between two federates. To run it start both the notebooks in that folder simultaneously and go back and forth.
- An example transmission-distribution exchange between PyPower and OpenDSS via OpenDSSDirect. Similar to piexchange, this requires starting two notebooks simultaneously that each setup a federate and then interact via HELICS.
- In these examples the HELICS broker is setup by one of the federates programmatically. It is also possible (and perhaps more common for large co-simulations) to start the broker directly using the executable provided by HELICS and then have federates attach.
- Similarly these examples illustrate configuring the federates and their data exchange programmatically. It is also possible to put this configuration information in a file and have HELICS read it in, which can make it easy to use the same federate code to be re-used as multiple different federates.
- For larger co-simulations, the helics-cli helps manage the process of configuring and starting a large number of federates.
If you are interested in running this demonstration on your computer, you can follow the installation steps below.
Tutorial Installation (optional)
- Install Miniconda3
- Run the following
git clone https://github.com/kdheepak/openmod-2019-helics-tutorial cd openmod-2019-helics-tutorial conda install jupyter conda install nb_conda conda env create conda init bash # use your appropriate shell here conda activate helics-environment jupyter notebook
You can check if everything has been installed correctly by running the following to start Python:
conda activate helics-environment python
When Python has started you can run the following:
>>> import helics as h >>> h.helicsGetVersion()
