“…The new 220 V DC system reduced the copper costs and maximized the space as the battery size was reduced by 30-40%. Another research study looked at switching to a 110 V DC system to replace an existing single-phase 220 V AC system or three three-phase 380 V AC system so that existing appliances can be utilized with fewer modifications [222]. The authors of [123] examined the new industry specification and global standard for data centers at 380 Vdc [29].…”

This manuscript presents a comprehensive review of recent advancements in electrical distribution networks, with a specific focus on the incorporation of direct current (DC) applications. The research aims to comprehensively address the current and future aspects of DC, spanning from the distribution level to the utilization level. The renewed interest in DC power systems has led to the investigation of several transitional challenges in recent years. A significant portion of these efforts has been dedicated to determining the feasibility of applying DC to specific use cases. Additionally, the literature has explored design considerations such as system architecture and voltage levels, the integration of DC into existing distribution networks, load flow (LF) computations, and the distinct safety concerns associated with DC power systems. In this paper, the various research endeavors are categorized, evaluated, and scrutinized to assess the current state of the transition from a purely alternating current (AC) distribution system to a solely DC or hybrid AC/DC distribution system. A bibliometric analysis is conducted, constructing a network of co-occurrence based on author-provided keywords, which reveals the primary research foci in this domain. The barriers hindering the widespread adoption of DC distribution systems and potential solutions are also discussed. Moreover, this article synthesizes ongoing efforts to address these obstacles and delineates future research directions by emphasizing the existing knowledge gaps.

This work demonstrates the possibility of using the available-in-market appliances in a DC-distribution system. This demonstration also represents an alternative migration from AC-distribution to DC-distribution. DC-distribution has been shown to be more efficient and provided good power quality in a distribution system. The power supply technology in the modern appliances makes the possibility of an appliance to be used in either both AC-distribution and DC-distribution without any modification. Appliances are tested by using an AC-source as the base-line and then the test replaces the ACsource by a DC-source.

In this paper, an adaptive control system for a dc microgrid for data centers is proposed. Data centers call for electric power with high availability and a possibility to reduce the electric losses and hence the need for cooling. By using local energy sources, high reliability can be achieved, and by using dc the number of conversion steps, and therefore also the losses, can be reduced. The dc microgrid can also be used to supply closely located sensitive ac loads during outages on the utility grid. The proposed dc microgrid can be operated in eight different operation modes described here, resulting in 23 transitions. The adaptive control system coordinates the control of converters, sources and switches used in the dc microgrid. The adaptive control system is tested in the simulation software packages PSCAD/EMTDC, and the results of the most interesting operation modes and transitions are presented. The results show that it is possible to use the proposed dc microgrid to supply sensitive electronic loads, and also during utility grid outages, supply closely located sensitive ac loads. To reduce transients in the voltage experienced by the sensitive ac loads, the dc microgrid requires fast utility outage detection and fast switches.
