Please help me solve this issue./ algebraic loop error containing model/powe​rgui/equiv​alentmodel​1/statespa​ce.

Hello, please help me solve this problem.

I am basically working on lvrt improvement of WECS using SFCLS. I am getting this error in my model

"Simulink cannot solve the algebraic loop containing 'power_pss_for_sfcl_addition/powergui/EquivalentModel1/State-Space' at time 0.30020254164893118 using the LineSearch-based algorithm due to one of the following reasons: the model is ill-defined i.e., the system equations do not have a solution; or the nonlinear equation solver failed to converge due to numerical issues."

I had searched earlier how to remove algebraic loops, but this one is inside powergui, so can't be removed.

If I do not apply a fault in my model, it runs without error. however, when i apply fault for [0.2 0.3](three phase to ground), this error is returned right after fault clearing.

besides, simulation speed is also very slow.

kind suggestions will be highly appreciated.

thanks.
