DC microgrids are gaining more attention with the increased penetration of various DC
sources such as solar photovoltaic systems, fuel cells, batteries, etc., and DC loads. Due to …

This research presents an optimum design scheme and a hierarchical energy management
strategy for an island PV/hydrogen/battery hybrid DC microgrid (MG). In order to efficiently …

A dc microgrid is a low inertia system dominated by power converters. As a result, the
change rate of the dc voltage is very fast under power variation. In this study, a distributed …

Renewable-based sources can be interconnected through power electronic converters and
connected with local loads and energy storage devices to form a microgrid. Nowadays, DC …

This paper proposes a coordinated power control method with virtual inertia (VI) for fuel cell-
based DC microgrids (MGs) cluster based on the multi-agent system (MAS) control frame. In …

Power buffers are dc-dc converters with large capacitors to provide inertia during microgrid
transients. This power buffer converter precedes the point-of-load (PoL) converter; the later …

Abstract In the Medium-Voltage DC (MVDC) ships, pulse load will cause great disturbance
to DC bus voltage. Hybrid energy storage (HESS) including Supercapacitor, Lithium …

Independence in energy generation, attention to environmental issues, limited fossil fuel
sources, and easy access to renewable energy sources have led governments, industry …

In dc microgrids, droop control is widely employed in power converters interfacing
distributed energy resources and common dc bus for automatic power sharing. In order to …

In this paper, inspired by the concept of virtual inertia in alternating current (AC) systems, a
virtual impedance controller is proposed for the dynamic improvement of direct current …
