in an islanded microgrid to control voltage and frequency, we need control methods such as droop control.In general, selection of the power

sharing coefficients and controller parameters carefully will promote the system performance against disturbances and load changes. in the sys with multiple DGs using trial and error methods to select voltage and current PI controller parameters consume time. Is there a step by step way to do it?

I could not get desirable results using given parameters in special paper.
