Controlling a bidirectional AC/DC converter stable with no power transfer

I'm trying to model a bidirectional AC/DC converter that can both transfer power from AC to DC and vice versa. Also, when set to zero no power (P*=0) should be exchanged, which is the case in the model attached to this question. I'm trying to control the voltage over the capacitor (Vc) at the DC side (which is in this case 400V) and the reactive current to zero (Iq*=0). Unfortunatly, only the DC voltage over the capacitor as well as the power transfer are controlled "correctly" (both go at least to the reference values). The d component of the current at the AC side (Id) is for some reason going to 1000A while it should be around 0A, with no power transfer. Furthermore, the q component of the current at the AC side (Ic) is controlled to go to 0, which is also not the case at this moment.
Does anyone has an idea what I'm doing wrong? I hope when this works I can change the value of the power exchange between both sides to nonzero values, while the converter still behaves as planned.
Please let me know!
Kind regards,
Sándor
