Direct Current (DC) microgrids are expected to become larger due to the rapid growth of DC energy sources and power loads. As the scale of the system expends, the importance of voltage control will be increased to operate power systems stably. Many studies have been performed on voltage control methods in a DC microgrid, but most of them focused only on a small scale microgrid, such as a buildi...

Historically, the development and design of distribution systems (DSs) microgrids (MGs) were based primarily on alternating current (AC) as a traditional approach due to many advantages such eliminating need for synchronization, well ease integrating distributed energy resources (DERs). Recently, given democratization DER through local installations renewable appliances using power electronics,...

This paper proposes a novel extended-single-phase shift (ESPS) control strategy of isolated bidirectional full-bridge DC-DC converters (IBDCs) which are a promising alternative as a power electronic interface in microgrids with an additional function of galvanic isolation. Based on the mathematical models of ESPS control under steady-state conditions, detailed theoretical and experimental analy...

This paper presents a distributed hierarchical control framework to ensure reliable operation of dc microgrid (MG) clusters. In this hierarchy, primary control is used to regulate the common bus voltage inside each MG locally. An adaptive droop method is proposed for this level, which determines droop coefficients according to the state-of-charge (SOC) of batteries automatically. A small-signal...

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 fa...
