摘要: DC networks that include storage systems, renewable sources, dc loads, and front-end converters can provide some advantages as compared with ac grids. However, the interruption of fault currents is difficult due to no-zero crossing current. Moreover, clearing time traditional circuit breakers be too long for protecting power electronics switching components. Multiport seem a good solution solving aforementioned problem. The introduction multiport dc/dc converter, along its configuration centralized control flow management, proposed in initial sections this study. After this, paper focuses on study system behavior during functioning conditions. Both pole-to-pole pole-to-ground faults are investigated. authors propose strategies hardware solutions overcome protection issues several types. Some numerical simulation results provided.
