In an all electric ship, the intelligent and integrated power system (IPS) that allows for reconfiguration offers better fight-through and survivability capabilities compared to manual service restoration. Automated reconfiguration involves optimizing the status of switches (ON/OFF) such that power delivered to loads is maximized after the occurrence of a fault. The priority is given to vital loads over semi-vital and non-vital loads while maximizing the power delivered. The novelty of the formulation presented in this paper is the consideration of non-radial power flow in a balanced hybrid (AC & DC) shipboard power system (SPS). Analysis of the original mixed-integer non-convex reconfiguration optimization is done by formulating appropriate low complexity convex form to reduce computation time. Comparative studies of cumulative distribution frequency (CDF) of the power delivered to loads for non-radial and radial configurations are presented to demonstrate the robustness of non-radial topology in case of multiple simultaneous faults.
