Vd, which is dependent on the model outputs, is fed-back to the model inputs which would have caused an algebraic loop if the filters were not present. The continued presence of the algebraic loop indicates that the V Filter and I Filter implementation probably has an unintended direct-feed through at some point during the simulation.
The proposed model bypasses the faulty filters with correctly functioning filters which breaks the algebraic loop.
