MÉTODOS DE NEWTON DESACOPLADO NA SOLUÇÃO DO FLUXO DE CARGA CONTINUADO

Abstract

This paper presents a study of theimplementation of decoupled versions of Newton, for thecontinuation power flow, to obtain the maximum loadingpoint of power systems. Makes use of the simultaneousresolution schemes and alternate. It is observed that themaximum loading point is of fundamental importancebecause it defines the boundary between the operatingregions of stable and unstable in terms of static voltagestability. The use of the angle of the voltage and voltage as aparameters was efficients for the determination of themaximum loading point. The results obtained for IEEE testsystem (14 and 30 buses), using the schemes mentioned,show that the alternate presents better performance that thesimultaneous. When compared to the Newton's Raphsonmethod, the scheme alternate shows satisfactoryperformance, not changing the final solution.Index Terms ⎯ Continuation Method, Decoupled Methods,Power Flow, Maximum Loading Point.
