Deliverable‐power dependence on distribution‐line resistance and number of loads in low‐voltage DC distribution system

Abstract

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