“…), with the AC network typically functioning as the primary supply source. Reference [254] analyzed the effect of different DC distribution network configurations on overall network efficiency. Before continuing with a discussion of DC network configurations, it is important to define the following two primary categories of configurations: (a) configurations without SST and (b) configurations with SST.…”

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 paper presents an in-depth comparison of the benefits and limitations of using a low-voltage DC (LVDC) microgrid versus an AC microgrid with regard to the integration of low-carbon technologies. To this end, a novel approach for charging electric vehicles (EVs) on low-voltage distribution networks by utilizing an LVDC backbone is discussed. The global aim of the conducted study is to investigate the overall energy losses as well as voltage stability problems on DC and AC microgrids. Both architectures are assessed and compared to each other by performing a power flow analysis. Along this line, an actual low-voltage distribution network with various penetration levels of EVs, combined with photovoltaic (PV) systems and battery energy storage systems is considered. Obtained results indicate significant power quality improvements in voltage imbalances and conversion losses thanks to the proposed backbone. Moreover, the study concludes with a discussion of the impact level of EVs and PVs penetration degrees on energy efficiency, besides charging power levels’ impact on local self-consumption reduction of the studied system. The outcomes of the study can provide extensive insights for hybrid microgrid and EV charging infrastructure designers in a holistic manner in all aspects.

One of the main environmental targets of the European Union is to improve the energy efficiency in order to reduce the emissions of greenhouse gases. This work presents a cost-effective optimization method for design engineers to maximize the energy efficiency of electrical installations during the design phase. Hence, besides the safety and capacity requirements that need to be ensured during the design procedure of an electrical installation, the energy efficiency during its operation will also be considered. Thus, the proposed multi-objective optimization technique, based on genetic algorithms, offers a design guideline for the placement of the distribution boards, for the cable sizes and for the equipment used, for maximizing the energy efficiency of the building and at the same time the cost effectiveness of the electrical installation. The proposed method has been implemented and validated using a commercial software (Modecsoft ElectricalOM) for electrical installation designs.
