Margem de estabilidade de tensão no planejamento dos sistemas elétricos: análise do impacto do despacho da geração

Abstract

This master thesis proposes an innovative methodology for calculating the voltage stability margin applied to power systems planning studies. Several parameters are investigated regarding their impact on voltage margin values. Special attention is given to the generation dispatch considered in simulation tasks. The main objective of this methodology is to help planning staff to decide about the more adequate generation distribution factors. This decision is based on the so called electrical distance between generation and load buses. This distance is one of the major factors that influence voltage stability margin identification.
