An iterative quota calculation method for congestion management and optimal grid …

This showcases how the IQC quota would react in a scenario without an actual grid congestion, but with grid voltage violations, illustrating the differences between both calculation methods. In both cases, the reference model sees no congestion, as the voltage is not an input to the model, hence it does not compute any quota in these cases.
