Abstract :
This paper proposes a comprehensive approach to mid-term voltage stability, combining fast simulation, instability diagnosis and corrective control determination. The fast simulation approximates the mid-term evolution by a succession of equilibrium points, thereby offering a good compromise between efficiency and accuracy. The instability diagnosis and corrective control determination consist of fast sensitivity analyses at some points of the simulated system trajectory, in order to identify critical points and determine the smallest changes in power injections required to recover stability. The method is illustrated on a real-life 1200-bus modelling of the French Western system
