Abstract
Under voltage load shedding (UVLS) plays a vital part in power system control when the system is subjected to large disturbances. Load shedding has been employed for long time as the last remedy to preclude major power system failure which is activated by under frequency or under voltage relays. This paper proposes an advanced method for under voltage load shedding incorporating the bus participation factor method to determine the location of load shedding. The main motivation of this study is to attain a better performance of UVLS. The proposed methodology is implemented on a 3-machine 9-bus test system. Dynamic simulation is performed to validate the robustness of the proposed method.
