Undervoltage load shedding is an economical way and one of the methods to prevent voltage instability. The concept of UVLS is to shed certain load to cover the voltage drop due to power system failure. This thesis will presents a scheme database of under voltage load shedding considering contingency which is transmission line outage. There will be two databases which are at normal load case and at peak load case. Both cases is considering contingency. Voltage stability analysis using bus participation factor technique to know the location of load that need to be shed is be discusses in this project. Power system analysis toolbox software and 14-bus IEEE test system is being use to perform dynamic simulation and the result is based on time-domain analysis.
