Tranmission & Distribution Co-Simulation Example

This is an example of a Simple T&D Co-Simulation. This example will take a simple static power system model and add a detailed secondary side with individual residences with a collection of devices such a HVAC, Water heater, Pool pumps, etc. Then also add a Transmission system using MATPOWER

To get started nagivate to the following folder within the main script base and open the coSimulationTD.py script.

# navigate to the repositories folder
cd $HOME/repositories

# from here navigate to main landing for experiment runs
cd modificationScipts
nano coSimulationTD.py

This script will contain all of the setting you have available for the experiment. The following will explain the settings:

# ---------------------------------------------------------------
# ----------------------- Settings ------------------------------
# ---------------------------------------------------------------

# name of the experiment
experimentName = 'tdExample'

# number of distribution systems in the experiment
distributionSystemNumber = 2

# create simple bash run scipt that will start a GridLAB-D instance per feeder
createRunScripts = True

# create HPC run scipt that will work with the Co-Simulation launcher capability
createHPCScripts = False

# this assumes that everything associated with this experiment is in a certain folder structure. This is the path to the root folder
rootPath = '/people/hans464/helicsUseCaseScripts'

# dictionary that holds all the log level information for each type of federate
simulatorLogLevels = dict()
simulatorLogLevels['fncs'] = 'WARNING'
simulatorLogLevels['matpower'] = 'INFO'

# specify the port fncs will use to communicate on

After modifying the setting for this script you can create and run the experiment by doing the following:

# navigate to the repositories folder
cd $HOME/repositories/HELICS-Use-Cases/PNNL-Real-Time-Transactive-Energy/modificationScripts

# run scripts to populate feeders
python coSimulationTD.py

# execute experiment
cd ../experiments/tdExample
./runAll.sh
