Phase Shift Transformer in a simple network

Hello!
I have only recently started working with pandapower and now have questions about phase shift transformers and their effects on the grid. I have attached a simple network.
My specific task is as follows:
I would like to simulate the loading of the two lines (line 1 and line 2) depending on all available transformer taps of transformer 1 (ideal phase shifter, 220/110 kV). Transformer 1 have the transformer taps -9--0--+9 with an additional phase angle of 60°. Loads and generations remain constant, only the transformer taps of transformer 1 are changed. The aim is for example to create a diagram in which the loading of the two lines are plotted against all transformer taps of transformer 1.
What is the best way to proceed and how can I best model such a phase shift transformer? Do I need a control module for this task?

I would be very happy to receive a few tips and would like to thank you in advance for your answers.

Does anyone have any ideas on how I could solve this problem?

and loop over the tap position
