Abstract :
A robust coordinated AVR+PSS, called the “desensitized Four Loop regulator”, has been designed for the French power system and is currently being implemented. It is shown here that it is possible to transform the structure of this controller into any standard IEEE AVR+PSS structure. The AVR+PSSs obtained in this manner are efficient for damping all kinds of electromechanical oscillations of a large scale power system (including inter-area oscillations). This approach is combined with modal analysis techniques. Its efficiency has been verified on several large scale systems and is illustrated here on a modified version of the New England system. The obtained AVR+PSSs have a good robustness against significant changes in the characteristics of the network
