✦ Synopsis

The stability limits for power systems can be defined by curves on the capability chart. In this paper the sensitivity of these curves versus system parameter perturbations is considered. The results also look interesting from a practical point of view, since a more realistic and efficient margin for stability can be defined. On this basis, the margin variations due to parameter perturbations are determined. Finally, a useful criterion is introduced to determine globally the influence of the parameter perturbations on the dynamic behaviour of the system.
