DC supply of low-voltage electricity appliances in residential buildings

This full paper concentrates on the results of technical and economical analyses of DC supply of low-voltage electricity appliances and application of low-voltage DC (LVDC) networks in electrification of real estates. This paper illustrates possible advantage that can be achieved by using DC voltage inside the premises. The main contribution of this paper relates to the suitability of electricity appliances for low-voltage DC and the influences of LVDC real estate distribution networks on the energy- and cost-efficiency of electricity distribution.
