Under Voltage Load Shedding (UVLS) has been successfully deployed in many systems throughout the world to protect local systems from voltage collapse. This is particularly true if the system conditions and the contingencies leading to voltage instabilities are of low probability, but would result in serious consequences. However, the locations and how much(More)
Heavily loaded condition may lead to power system instability either due to sudden increase in load or tripping of adjacent transmission line. When load increases, the apparent impedance decreases accordingly depending on the nature of load, similar instances can be observed during short circuit event [1, 2]. In addition, the system may also experience(More)
Modern power system network are usually operated to its maximum capabilities. This in turn would expose the system towards possible voltage instability condition. Coupled with peak load condition where lines can be loaded to its limit, probable scenarios relating to voltage instability could lead to tripping of overload lines which would then lead to(More)
