Adequate security margins are commonly applied in power systems by keeping predefined transfer limits through certain transmission corridors in the system. These limits are often set to keep the criterion stating that the system should remain stable after the loss of any component. For many stability criteria such as, voltage stability, and voltage limits at specific nodes, the distribution of the injected power amongst the nodes of the system will be of vital importance. To incorporate this into the analysis of transfer limits the uncertainties in nodal loading and wind power production will have to be considered. In this article we propose a new method for generating samples of the power at all nodes given a set of transfers through specified corridors of the power system. It is then shown how the method can be used to evaluate the risk of violating the system stability limits induced by choosing a specific set of transfer limits. The method can be used in power system operations planning when setting the limits for trading and transfer between the different nodes of the power system.
