Abstract
An advanced fuzzy logic control scheme has been proposed for micro-computer based power system stabilizer (PSS) to enhance the stability of power systems. In the proposed control scheme, additional integral information of generator speed is taken into account to enlarge the stability region together with propotional and differential information of generator speed. Namely, the advanced control rules are based on the PID information of generator speed. Various simulations have been performed subject to several types of large and small disturbances using a one-machine and an infinite-bus model system. In addition, comparison studies have been made between a conventional analog-type PSS and the fuzzy logic PSS. The results show that the stable region of the study system is highly enlarged up to the physically stabilizable boundary by the proposed fuzzy logic control scheme.
