In voltage security assessment it is of great importance to determine the most critical
contingencies of the system. However, most of the contingency ranking methods fail to …

This paper presents a framework for real-time contingency screening using a situational
awareness oriented tool. While some contingencies might have a significant impact on …

Installation of reactive compensators is widely used for improving power system voltage
stability. Reactive compensation also improves the system loading margin resulting in more …

An increase in demand for electric power has forced utility transmission systems to
continuously operate under stressed conditions, which are close to instability limits …

La estabilidad de voltaje se define como la capacidad de un sistema de potencia de
mantener valores de voltaje dentro de límites previamente establecidos en todos los buses …

In recent years, power systems are often operated close to instability due to an increase in
human power consumption or usage. Therefore, the problem of Dynamic Security Analysis …

El fuerte crecimiento y, penetración de los sistemas de generación distribuida en los
sistemas de potencia, conlleva a la necesidad de evaluar el impacto que tiene sobre la …

Dentre as diversas técnicas existentes para o estudo de estabilidade em sistemas elétricos
de potência, destaca-se a análise de contingências. Esta abordagem é importante tanto nas …

Contingency ranking is one of the methods used in power system operations and planning
to foresee the behavior of a system when there is a large disturbance in the system. Several …
