Medium Voltage Direct Current will be the enabling technology in the shipboard power systems of tomorrow. In such grids, the stability assessment results of paramount importance, as the pervasive presence of power converters can lead to system instability. In presence of perturbations, dynamic interactions between high bandwidth controlled converters and LC filtering stages can indeed provoke unstable behaviors, thus the consequent ship blackout. By adopting the Eigenvalues method, the paper performs the small-signal stability analysis on a DC shipboard power system. Once recognized a system perturbation (i.e. generating converter disconnection) as destabilizing, the virtual Active Damping effect is consequently tuned to re-establish the DC grid stability. Poles repositioning in the left-half plane and dynamics simulations will justify the designed control's capability.
