In this paper a model of PQ sources useful for distribution systems analysis is developed. In the considered systemsthere are, in addition to HV/MV sources, other PQ buses, namely active and reactive power supply nodes (Vδ nodes).The general solution strategy is an iterative forward/backward method, in which the state variables are the nodevoltages. If it is weakly meshed, the network is turned into radial by means of cuts and compensation currents. After thepresentation of the general problem, the equations expressing the unknowns for the PQ nodes are treated in detail.These equations belong to the backward sweep of the algorithm. The methodology has been implemented and appliedso as to test its performance in terms of calculation times and precision.
