A two-step method for reconfiguration of shipboard power system

The modern shipboard power system integrates heavy loads and has less fault tolerance than the conventional power system. Therefore, a fast and high-performance reconfiguration scheme is needed when a fault occurs. In this paper, a two-step reconfiguration method is proposed to achieve a rapid and optimal reconfiguration scheme for shipboard power system. This method at first employs graph theory to generate an emergency reconfiguration which can quickly restore the system with relaxed operation constraints. Then, the particle swarm optimization (PSO) algorithm is used to improve the reconfiguration scheme while considering multiple objectives and stringent constraints.
