power system (the DG supplies its power to a part of the public distribution system that has been separated from the Therefore it seems to he useful to investigate a possible DC the increasingly Abstract-The need of a high quality of the electricity supply has induced many customers to equip their plants with utility's power System). appliances (UPS) that have inside a DC section in which it is inserted a storage system. Moreover the technological progress distribution solutions (taking into ..distribution svstem interfaced with the public distribution circuital solutions that allow to connect loads and generators network by means of an inverter. This substantial modification will involve new strategies concerning the control and protection philosophies for the new distribution systems and also for load and distributed generators.In this paper it will he considered the use of a DC low voltage local network; in particular, under the hypothesis to employ the existing LV AC cables, a comparison concerning losses and transmissible power behveen AC and DC distribution scenario is performed.This paper was developed within the activity "Ricerca di Sistema" (DM 28/02/2003).
