N2 - A methodology for the analysis of radial or weaklymeshed distribution systems supplying voltage dependent loads isdeveloped. The solution process is iterative and, at each step, theloads are simulated by means of impedances. The network isdivided into two sub-networks which must be solved separatelyand sequentially; in the first, named RP-net, only the linesresistances and the loads shunt equivalent resistances areconsidered; in the second, named XQ-net, only the linesreactances and the shunt equivalent reactances are taken intoaccount. After a brief presentation of the b/f method, which iscurrently the most commonly used technique to solve distributionnetworks, the proposed methodology is detailed both for radialand for meshed systems. Finally, some results are presented inorder to evaluate the performances of the methodology in termsof number of iterations and precision.
