In this paper, a novel strategy for virtual impedance design in droop-connected converters is analysed; the method is based on the stability analysis of equivalent system loops and aims at defining feasible operating regions of the converter depending on the control parameters. The effect of the tuning on the regulating performances of the system then has been tested in a simulation environment.
