Power System Stability Enhancement Using ANN Based Coordinated Emergency Control System

The paper presents an emergency control system based on the artificial neural network (ANN) technique. The control system is able to find a coordinated control action (load shedding, generator tripping) to prevent the violation of power system stability. Besides, the coordination of FACTS with conventional emergency control actions is studied. A 14 bus test power system is used as a case study. The efficiency of the proposed technique has been proved by numerical simulations under different power system operating conditions and for different emergency situations. The results obtained are presented.
