Abstract

Steady state power system insecurity such as transmission lines being overloaded causes transmission elements cascade outages which may lead to complete blackout. The power system operator must know the system state at any instant. The contingency analysis predicts which contingencies make system violations and rank the contingencies based on sensitivity. Active power, reactive power and maximum loadability index have been derived. For all contingencies performance indexes have been computed using Newton Raphson power flow method in MATLAB environment. Ranking is done on the basis of sensitivity approach. Sensitivity is the change in load bus voltage w.r.t. change in load. In this paper contingency screening & ranking with voltage stability consideration is performed on IEEE 5 bus system using developed methodology.
