Estabilidad de voltaje en sistemas de transmisión considerando la operación de transformadores con TAPS

Abstract

This document presents a voltage stability research, considering the inclusion of transformers with taps, knowing that the variation in the number of turns in transformers changes the voltage magnitude in buses. In order to analyze the voltage stability, the continuation power flow method is used to create PV curves. This power flow formulation integrates the generalized model of a transformer with taps. The proposed cases are set as a function of the direct and inverse control that transformers can make. The results allow determining which tap positions modify the points of voltage collapse, improving or worsening the voltage stability in the test SEP.
