Electricity management involves a series of interconnected activities between the nuclear industry and its customers in order to rationalize electricity consumption. In this way, both the electricity supplier and the consumer will benefit more. Electricity management has a logical output and different plans to reduce energy consumption. Direct current (DC) distribution has recently been considered in building research due to increased on-site generation and battery storage, and the increasing prevalence of DC internal loads. In terms of performance comparison, DC current distribution buildings are much more efficient than AC distribution buildings. With the increase of distribution generation penetration coefficient, DC distribution network has been gradually considered due to higher quality, lower losses and larger distributed energy compared to AC distribution network. The DC distribution system has the potential to eliminate many of the conversion losses in AC building distribution networks, which include photovoltaic and DC end-uses. This means that AC / DC converters can be eliminated using the DC distribution system, which reduces losses. In this paper, we examine the development of direct current (DC) networks from a technical and economic point of view using domestic and commercial loads. A review of the achievements achieved in this regard and a sample of work done in this regard is provided.
