SimPowerSystems: Wind turbine DFIG model on weak grid

Hi, i am modelling a wind-farm cluster consisting of DFIG wind turbines. It operates without problems in phasor simulation method as long as the impedance of the grid it is connected to is low. But when i try to simulate a weak grid, the terminal-voltage collapses and the transferred active and reactive power oscillate and go to zero.

Is anyone familiar with the DFIG model of the SimPowerSystems toolbox and can help me solving the problem?

Thank you very much! Robin
