Indeed the behavior of this power transmission network are very complex and present problems of instability such as short circuits, oscillation at low frequency, an overvoltage etc. For that, the simulation with the Power World Simulator 15 software, the use of the automata and the means of protection makes it possible to predict the behavior of our network and to bring it back in its stable dynamic regime in the event of the persistent disturbances
