A novel approach for real-time implementation of MVDC shipboard power system reconfiguration

In a Shipboard Power System (SPS), faulty components are separated from the rest of the system after the occurrence of faults. In this situation, it is important to quickly restore the power supply to the affected parts of the SPS and reconfigure the system to improve its reliability and ensure safe and satisfactory operation of the system. Similar to terrestrial power systems, onboard post-fault reconfiguration aims to ensure the maximum delivery power/service to the system's loads following a fault. In this paper, in order to deal with the reconfiguration problem during the fault situations in Medium Voltage DC (MVDC) SPS, a real-time Simulated Annealing (SA)-based reconfiguration technique is designed and implemented in the Real-Time Digital Simulator (RTDS). To validate the proposed approach, two MVDC SPS models including four and six zonal loads are used to simulate several fault scenarios. The simulation results demonstrate the effectiveness of the proposed approach to reconfigure the system under different fault situations in the real-time operation of the SPS.
