Undervoltage load shedding to avoid voltage instability / Mohd Firdaus Mohd

This thesis presents a comparative measurement for under voltage load shedding in power system. The technique for comparing the voltage profile for the particular bus is developed by using the Simulink. The voltage profiles for this condition: initial condition, some loads are shed; some generators are turned off, at stressed condition, and also in the event of line outage condition; are observed. From the observation, the condition of voltage level can be determined. Result shown that when the load shedding is applied, the voltage profile at any particular bus is better. This can avoid the voltage instability for the system that can lead to the event of voltage collapse.
