Abstract :
DC networks that include storage systems, renewable sources and Front End Converters can provide some advantages compared with AC grids. On the other hand, the interruption of fault currents is difficult due to no-zero crossing of the current. The use of traditional DC circuit breakers is not sufficient to protect power electronics switching components. In this paper, an introduction of a multi-port DC/DC converter is proposed to solve the aforementioned problem, and achieve a smart power flow management. Moreover, both pole-to-pole and ground faults are investigated, and some numerical simulation results are provided.
