文摘This paper presented PSS (Power system stabilizer) design based on Genetic Algorithm - Fuzzy PID (Proportional Integral and derivative) or GAFPID. GAFPID based PSS design is considered for multimachine power system. The main motivation for this design is to stabilize or to control low-fi'equency oscillation and terminal voltage of power systems. Genetic Algorithm (GA) is employed for the optimization of the parameter of stabilizer. By minimizing an objective function in which the oscillatory speed deviation of the generator, small signal and large signal performance of the system is improved. The effectiveness of the proposed PSS in increasing the damping of system electromechanical oscillation is demonstrated in a simple two-area power system.
