Abstract:

Power system stability is the concept in which all operating parameters are within the limits. Sometimes power systems face various network operating problems due to change in network configuration when subjected to line outage contingency due to various reasons. To provide appropriatesecurity, it is desirable to analyse the effect of contingencies and plan suitable steps for enhancing system stability limit. Network contingency ranking is evaluated considering composite criteria based on fuzzy logic approach. Network contingencies not only over load the branches, but also lead to unsatisfactory voltage limit leading tovoltage collapse. This paper presents an approach to choose proper transmission corridor to place the FACTS device-unified power flow controller (UPFC) under normal and line outage contingencies.Thishas been tested under simulated conditions on a Indian power system networkand the results for a 25 node equivalent EHV power network is illustrated.
