Abstract [en]

Adequate security margins are commonly applied in power systems by keeping predefined transfer limitsthrough certain transmission corridors in the system. These limits are often set to keep the N-1 criterionstating that the system should remain stable after the loss of any component. For many stability criteria suchas, voltage stability, and voltage limits at specific nodes, the distribution of the injected power amongst thenodes of the system will be of vital importance. To incorporate this into the analysis of transfer limits theuncertainties in nodal loading and wind power production will have to be considered. In this article wepropose a new method for generating samples of the power at all nodes given a set of transfers throughspecified corridors of the power system. It is then shown how the method can be used to evaluate the risk ofviolating the system stability limits induced by choosing a specific set of transfer limits. The method can beused in power system operations planning when setting the limits for trading and transfer between thedifferent nodes of the power system.
