Identification of optimum location for stabiliser applications using participation factors

The paper presents a novel approach for the identification of the optimum site for power-system stabilisers. The proposed method makes use of participation factors to locate the generator in a multimachine power system which is most effective in damping enhancement using power-system stabilisers. A comparative study between the proposed approach and the conventional eigenvector method has been performed on two utility systems. It is found that the participation factor method is a better criterion for the determination of optimum stabiliser location.
