TGGS Special Block Lecture about Smart Grid Technology

by the Intitute for Automation of Complex Power Systems

Introduction to Modelica with OMNotebook

1. Double click on the Home folder icon
2. Navigate to the folder gits/tggs/omnotebook_exercise
3. Double click on rlc - Student.onb
4. Now, you can start completing the OMNotebook.

Note: Each model must be initialized by executing each cell with shift+enter

Grid Modeling and Simulation - CIMverter, ModPowerSystems and OMEdit

Note: You can copy the commands with ctrl+C and paste them in the terminal with ctrl+shift+V

CIMverter usage

Open a new Terminal and enter

cd ~/gits/CIMverter/build/bin

to change into the proper directory of the CIMverter.

Then enter following command for the conversion of a sample grid in CIM to a Modelica system model file called CIGRE.mo:

./CIMverter -a ../../samples/CIGRE_MV_Rudion_With_LoadFlow_Results/ -o CIGRE

This CIGRE grid can be simulated by OpenModelica based on the ModPowerSystems library:

Simulation with OpenModelica

For simulating the generated CIGRE.mo grid:

1. Double click the OMEdit icon on the desktop
2. Choose File -> Open Model/Library File(s) from the menu
3. Starting from the home directory, choose the file gits/modpowersystems/ModPowerSystems/package.mo
4. Choose File -> Open Model/Library File(s) from the menu
5. Starting from the home directory, choose the generated file gits/CIMverter/build/bin/CIGRE.mo
6. Click on CIGRÈ in the left menu of OMEdit
7. Execute the simulation by choosing Simulation -> Simulate from the menu

Further Insights

You can have a look into the CIM data with

cd ~/gits/CIMverter/samples/CIGRE_MV_Rudion_With_LoadFlow_Results/
mousepad Rootnet_FULL_NE_24J13h_EQ.xml

To see the templates which the CIMverter applies to obtain ModPowerSystems compatible models, go to

cd ~/gits/CIMverter/ModPowerSystems_templates/

You can view the system model template with

mousepad modelica.tpl

and a exemplary component model template with

mousepad Transformer.tpl
