Genetic algorithm based inter-area oscillation damping controller design using MATLAB

This paper presents a GA based optimization scheme for simultaneous coordination of multiple power system damping controllers. Both, local and remote, measurements are considered as input signals to the damping controllers. The proposed algorithm is applied to tuning of single and multiple power system stabilizers as well as tuning of a static VAr compensator. Controller design is tested on the small and mid-sized power systems to prove its effectiveness. All simulations are carried out using the MATLAB based package for nonlinear simulations of power systems, Power Analysis Toolbox (PAT), developed at West Virginia University´s Advanced Power Engineering Research Center. Controllers are designed using MATLAB Control System Toolbox and optimized using GAOT toolbox.
