The utilization potential of LVDC distribution

Low voltage direct current (LVDC) distribution is a promising solution, which benefits are large power transfer capacity with low voltage and improvements to reliability and power quality. Tests by the pilot implementation in Elenia Oy have given promising results. The power transfer capacity of the system has been calculated in the paper using voltage drop and maximum load of cable as boundaries. The branches of the MV network, which can be replaced by LVDC distribution, are determined based on the calculations and mass computation of the whole distribution area of Elenia Oy. Based on the done analysis, it can be inferred that LVDC distribution has a good utilization potential.
