I. Introduction
Due to the increased penetration of distributed energy resources with inherent DC nature, such as photovoltaics (PV), battery energy storage systems (BESS) and electric vehicle batteries, but also DC loads, such as LED lights, microprocessors, laptop/cellphone batteries, etc., there is a growing interest in both academic and industry environments towards low-voltage (< 1500 Vdc) DC microgrids (DCMGs) (see Fig. 1), owing to numerous advantages of DC power distribution [1], [2]. Typical application cases involve commercial buildings, industrial plants, datacenters, EV charging stations and marine. The main motivation for introducing DC microgrids comes from expectedly increased power conversion efficiency due to reduction in number of the power conversion stages, which underpins the process of the power grids decarbonization. As described in [3], in industrial plants with energy recuperation, moving from the AC to DC distribution brings a measured efficiency improvement of 5.87 %. Further benefits involve potential cost reduction and more resilient operation of the system.
