Mission Based Reconfiguration for Hybrid Shipboard Power Systems Considering Threats*

In the recent years, the automatous operation of All Electric Ships (AES) has gained a lot of attention from both academia and industrial researchers as one of the most promising prospects for the transformational control development of new generation electric ships. In this paper, the reconfiguration problem of shipboard power system (SPS) considering external threats is investigated from the perspective of hybrid and distributed. By constructing a two-layer distributed control framework, mission commands are interpreted by coordinator and then send to zonal controllers, while reconfiguration actions can be performed in-zone by zonal controllers or among multi-zones by coordinator to complete the mission. Based on the extended hybrid model of SPS developed, the subsystem reconfiguration and coordinate algorithm are proposed. Finally the practical example of SPS facing threats is provided to illustrate the process to choose the optimal reconfiguration strategy.
