Our research project considers the restoration of electrical power systems after a significant disruption due to natural disasters such as hurricanes, and earthquakes. In this work, we focus on ensuring the stability of the grid with respect to transient effects that occur during the first few seconds following a restoration action. The problem can be modeled as a nonlinear program with differential equations describing the short-term reaction of power generators. In this work, we identify critical constraints that guarantee transient stability after a line switching. If the current configuration is unstable, we propose an optimization model allowing to find the closest stable state with respect to the original restoration plan.
