Protection Systems for DC Shipboard Microgrids

In recent years, shipboard microgrids (MGs) have become more flexible, efficient, and reliable. The next generations of future shipboards are required to be equipped with focuses on energy storage systems provide all-electric shipboards. Therefore, the must very reliable ensure operation all parts system. A MG should protected from system faults through protection selectivity minimize impact facilitate detection location faulty zones highest accuracy speed. It is necessary an across-the-board overview in DC This paper provides a comprehensive review issues challenges faced MGs. Furthermore, given different types components utilized MGs, fault behavior analysis these provided highlight requirements for their protection. divided into three sub-systems, namely, detection, location, isolation. comparison existing isolation schemes, traditional modern techniques, MGs presented advantages disadvantages each scheme.
