Analysis of optimized reconfiguration of power system for electric ships

Reconfiguration involves optimizing the status (ON/OFF) of switches such that power delivered to loads is maximized after the occurrence of a fault. The optimized reconfiguration prioritizes power delivered to vital loads over semi-vital and non-vital loads. The formulation presented in this paper is an extension of the work in to new balanced hybrid (ac & dc) shipboard power systems (SPS). Analysis of the non-convex reconfiguration formulation is done by appropriate non-convex solver and by convex approximation. The non-convex solution provides bounds on the optimal performance of the problem while the convex approximation reduces the complexity. Number of faults against the power delivered to loads is presented to showcase the system robustness against random fault scenarios.
