Copying answer from comments: Question askwer did not respond to request for additional information:
Fortunately I'm working on the same project. Glad to see another person working on the same =) I've designed a DG source (Micro Turbine Generator) for connecting it to utility grid. Then I wanted to check the rate of change of freq/voltage with DG end and Point of common coupling. From what you have said, your DG is supposed to fail supplying adequate power to loads in islanding condition. So the freq will drops and the only thing I didn't understand is, how could the power output of your sync gen increases with loss of mains? Could you elaborate your problem. May be we could discuss together and continue our project.
