Abstract
A power distribution system configured as a radial network includes buses having respective voltages, and distribution lines having respective currents. The radial network interconnects the buses with the distribution lines in a tree-like manner. A bus has a link to at least two distribution lines. The bus voltages and distribution line currents are determined by a processing circuitry configured to receive a Branch Matrix (BM) iteratively determine currents for the distribution lines and voltages for each of the buses until a difference is below a predetermined tolerance, and output final bus voltages and final distribution line currents. The circuitry iteratively determines the currents by determining a current matrix (CM) using the BM, and by determining the currents for the plurality of distribution lines in a zig zag manner over the matrix elements in the CM. The system finds a solution using fewer iterations than the backward forward sweep method.
