A Backward Method for Solving PV Nodes in Weakly Meshed Distribution Networks

Risultato della ricerca: Otherpeer review


In this paper, a new iterative backward/forwardmethodology for the load flow solution of weakly meshedsystems with fixed voltage nodes is presented. Suchtechnique models the loads at each iteration by means ofimpedances, and the PV nodes by means of reactances.Each iteration is organised in two steps. In the first, theradial network attained from the meshed system throughcuts and composed of shunt and series impedances issolved. In the second step, based on a reduced Théveninimpedance matrix, the compensation currents to beinjected in the cut nodes are deduced. Modelling the PVnodes by means of reactances allows the attainment, forthe reactive power of these nodes, of the same precisionthat it is possible to get solving the network with themethods usually adopted for transmission networks. Afterthe presentation of the different implementations of thebackward/forward method proposed in the literature, thenew technique and the relevant implementation arepresented in detail. The methodology allows the solutionof systems with meshes and PV nodes; test results showprecision, speed and good convergence properties.
