Power quality is a key issue in islanded electric power systems. Considering the intrinsic weakness of islanded grids, this paramount aspect is not of easy accomplishment. To fulfill power quality requirements in these weak electric systems, high performance voltage and frequency controls are needed, although the interactions between these controls can lead to stability issues. In particular, frequency and voltage controls’ bandwidth overlapping may produce destabilizing actions. In this paper, a study of the electromechanical stability in shipboard integrated power systems is presented, with particular reference to the case in which voltage and frequency controls dynamically interact.

Abstract
Power quality is a key issue in islanded electric power systems. Considering the intrinsic weakness of islanded grids, this paramount aspect is not of easy accomplishment. To fulfill power quality requirements in these weak electric systems, high performance voltage and frequency controls are needed, although the interactions between these controls can lead to stability issues. In particular, frequency and voltage controls’ bandwidth overlapping may produce destabilizing actions. In this paper, a study of the electromechanical stability in shipboard integrated power systems is presented, with particular reference to the case in which voltage and frequency controls dynamically interact.Pubblicazioni consigliate
