Abstract

In this paper, we show that in a low-voltage DC distribution system the deliverable power to a load has an upper limit Plim due to the voltage instability at the receiving ends. On the basis of the previously derived concept of Plim, we obtain the dependence of Plim on the distribution line resistance R. In addition, we investigate the influence of the number of loads on Plim. The result shows that a distribution line of lower R causes Plim to be lower. This reduction in Plim becomes more distinct for a larger number of loads.
