MÉTODO DA SOMA DE POTÊNCIAS PARA SOLUÇÃO DO FLUXO DE POTÊNCIA EM REDES DE DISTRIBUIÇÃO TRIFÁSICAS E DESBALANCEADAS

the power sum method (PSM) is very accurate for solving flow and has a fast convergence in radial networks. Its formulation represents balance terms of flows lines. This facilitates its application optimal model by composing part set equality constraints. As conventional PSM uses positive sequence representation distribution networks are three-phase unbalanced, then, this work, an expansion fundamental equation proposed to calculate nodal voltages. The process evaluating accuracy comparatively carried out through solution under unbalanced network 135 buses.
