automatic tap regulation disabled

[willemijnbrus]

hi pgm team,
We added an autmatic tap regulator like in the example notebook (see code below).
we want to make it a choice whether the model runs with the given information about the tap position (transformer["tap_pos"] ) or with automatic tap regulation. Is it correct that when we put TapChangingStrategy.disabled in the calculate_power_flow() function, the loadflow will use the tap pos assigned to the transformer and ignore the information we added on the transformer_tap_regulator?

transformer_tap_regulator = initialize_array(
    DatasetType.input, ComponentType.transformer_tap_regulator, 1
)
transformer_tap_regulator["id"] = [888888888]
transformer_tap_regulator["regulated_object"] = transformer_id
transformer_tap_regulator["status"] = [1]
transformer_tap_regulator["control_side"] = [BranchSide.to_side]
transformer_tap_regulator["u_set"] = [400.0]
transformer_tap_regulator["u_band"] = [20.0]
transformer_tap_regulator["line_drop_compensation_r"] = [0.0]
transformer_tap_regulator["line_drop_compensation_x"] = [0.0]

Hi @willemijnbrus ,

Indeed, the TapChangingStrategy.disabled enum value has exactly that purpose. In fact, the PowerGridModel.calculate_power_flow() function by default uses that value as well (see image below).

I hope this answers your question.
