This submission contains MATLAB scripts that will build automatically the IEEE 906 Bus European LV Test Feeder in Simscape Power Systems Specialized Technology. The model is a 'quasi-steady' model, meaning it captures an operating point in the minimum number of simulation steps. This is equivalent to a power flow, but enables multiple operating points to be assessed in a time-domain environment. The model can be built both as a single model, or as a four-segment model that is connected through Model Reference. Segmenting the model allows larger models to be built more efficiently, with time savings made in both model construction and model compilation.

Hi Graham, thank you for sharing.
Follow your steps:
This will create a model called 'IEEE_European_LV_COMPLETE'
The system is set up to run with Ts = 1, and load changes every 60s for a 24hr period.
To run the model, open and run 'IEEE_MR'. This is the top-level model that uses model reference to connect to 'IEEE_European_LV_COMPLETE'. Model reference is used so that we need only compile 'IEEE_European_LV_COMPLETE' once.
Once the model is compiled, in 'IEEE_MR' go to Configuration Parameters -> Model Referencing -> Rebuild and select 'Never'. Subsequent runs will not rebuild the model.
However, I have a problem when runs the "IEEE_MR" file:
Unable to update models referenced by 'IEEE_MR'.
The model 'IEEE_MR' has the Rebuild parameter on the Model Referencing pane of the Configuration Parameters dialog box set to Never. However, the following referenced models are out-of-date for the following reasons. Consider resetting the Rebuild parameter to a value other than Never.
Model reference simulation target (IEEE_European_LV_COMPLETE_msf.mexw64) for model IEEE_European_LV_COMPLETE is out of date because IEEE_European_LV_COMPLETE_msf.mexw64 does not exist.
Do you know how to solve it?
Thank you for your detailed model. How can I get the voltage, phase angle and current values of each bus on 1-minute basis? Thank you!
When you run create_European_LV_4segments.m to generate the four segment model, you will generate the different load inputs. Check out lines 108-118.
Change the scripts as necessary to load the correct data.
thank you for the model, but when trying to run init_European_LV_1SEG.m,
I get the message:
Undefined function or variable 'load_inputs1'.
Error in rampInputs (line 7)
ll = zeros(numel(t)*2,size(load_inputs1,2)+size(load_inputs2,2)+size(load_inputs3,2)+size(load_inputs4,2));
Error in init_European_LV_1SEG (line 16)
Any suggestions for the solution? When I check the data files, there are no load_inputs1, 2 or 3, only one file named load_inputs
Also, in the function init_European_LV_1SEG.m, in line 7, the inital code is: load('IEEE_European_LV_COMPLETE.mat'),
but there is not that named .mat file available, but a bit diffrent: IEEE_European_LV_COMPLETE_input_data.mat
