Title in Portuguese
Uma contribuição ao estudo da estabilidade de tensão em sistemas elétricos de potência: novos aspectos relacionados à representação da carga.
Keywords in Portuguese
Análise modal
Estabilidade de tensão
Modelagem da carga
Modelagem multimáquina
Abstract in Portuguese
Esse trabalho investiga o impacto do comportamento transitório e em regime permanente da carga sobre a estabilidade de tensão do sistema elétrico. Para isso, utiliza-se uma modelagem detalhada da rede elétrica, capaz de representar os principais eventos inerentes aos fenômenos de instabilidade e colapso de tensão. A simulação numérica do sistema algébrico-diferencial resultante é realizada utilizando-se o solver DASSLC. Ao final desse trabalho, faz-se uma análise da resposta dos diferentes modelos de carga sobre a estabilidade de tensão do sistema de 14 barras do IEEE.

Voltage stability
Abstract in English
This work investigates the impact of transient and steady state load behavior on power systems voltage stability. In order to do this, a detailed electric power system model is used to reproduce the main aspects of voltage instability and collapse phenomena. The numerical solution of the resulting non-linear differential-algebraic equations is carried out by using the DASSLC solver. An analysis of different load models behaviour for some voltage instability situations is presented for IEEE 14 bus system.
