Coordinated synthesis of PSS parameters in multi-machine power systems using the method of inequalities applied to genetic algorithms

A new method has been proposed based on the method of inequalities for the coordinated synthesis of power system stabilizer (PSS) parameters in multi-machine power systems in order to enhance overall system small signal stability. Since the coordination and control of PSSs is a Pareto-optimization problem, a comprehensive list of design objectives has been presented in terms of a set of inequalities. To solve these inequalities, genetic algorithms have been applied to determine the PSS parameters.
