Abstract :
In this paper improved branch-based voltage stability proximity indices are proposed. Their computation does not require the use of equivalents nor matrix handling, being straightforward and fast. They can be a very useful tool for power systems operators and planners both to evaluate systems operating conditions, and to determine system reinforcement actions. Also, the indices can be used to compare different operating situations as far as voltage stability is concerned.
