This study revisits the use of the direct current (DC) distribution system concept in
households to increase energy savings and potentially reduce costs and associated …

Direct-current (DC) power distribution has been used ever since electric grids were
invented, but, for the last century, low-voltage dc has been largely limited to a variety of …

DC-based microgrids are promising solutions to enhance the energy efficiency, reliability
and safety of residential and commercial buildings, as well as to provide more effectively …

Matching electricity demand to supply will be a growing challenge in the future. We argue for
the need for further research into local power distribution with a focus on “nanogrids”. We …

Series dc electric springs (series ESs) can tackle the intermittency of the renewable
generations (RGs) with reduced storage capacity in dc microgrids (MGs). They can actively …

Many aspects of our electricity systems are rapidly changing, including the ability to locally
generate power with renewable energy sources and integrate local storage. Key factors that …

This paper presents a smart residential electric power supply system, which is named smart
gateway grid (SGG). It can enable residential distributed generations (DGs) and energy …

In the near future, the digitalizing world will continue to improve and the need for DC based
devices will be increased beyond doubt. Today's electrical grid is strictly dependent on AC …

Alternating Current (AC) is the most common form of power available within buildings. This
has historical reasons rooted in large-scale utility generation and distribution of power. With …

The major objective of this study is to determine if direct current (DC) should be used at low
voltage levels in distribution networks. This idea stems from the increasing proliferation of …
