| Abstract | ||||
| The phenomenon of voltage collapse eclipses a potential hazard for the transmission and distribution systems. The load shedding for avoiding the existence of voltage instability in power systems is taken as a remedial action during emergency states. Te load shedding strategy for power systems with location and quantity of load to be shed is presented in this paper. Two methods are used for this purpose. The first method is based on a mathematical calculation of an indicator of risk of voltage instability. The second method is based on a fuzzy load shedding based algorithm that uses a voltage stability indicator for averting voltage collapse. Applications to the standard IEEE 14- bus system are presented to validate the applicability of the two proposed methods. | ||||
