MVDC power system voltage control through feedback linearization technique: Application to different shipboard power conversion architectures

Abstract

MVDC distribution systems are proving to be a very promising research topic, given the large number of studies proposed in the academia and in the navies worldwide. In this paper authors present some multi-machine MVDC distribution system architectures, exploiting and comparing a range of choices on the topic of voltage control. Three network topologies are presented and analyzed, applying a series of tests which include load connections and fault events. Considerations about engineering feasibility, control complexity, performance and possible improvements are given as conclusions.
