Integrated Electric Power System supervision for reconfiguration and damage mitigation

Yasar, Murat / Beytin, Adam / Bajpai, Gaurav / Kwatny, Harry G.

Autonomous shipboard electric power system operation is one of the major goals in order to ensure safe, reliable and economic system operation. Integrated Electrical Power Systems need to be capable of redistributing power almost instantly in order to supply both non-propulsion and propulsion shipboard electrical loads. The dynamics of the power systems require differential-algebraic equations along with discrete switching actions to account for load shedding and redistribution. Therefore, the reconfiguration problem can be formulated in a hybrid supervision framework in order to have a complete system description. The supervisory system will also be required to accommodate faults and failures to achieve damage mitigation. The paper discusses an approach of hybrid supervisory reconfiguration and damage mitigation in the context of a novel architecture of shipboard electric distribution systems.
