Determination of PSS location based on singular value decomposition
In a multi-machine power system, it is important to determine the best location for the application of power system stabilizers. A technique based on singular value decomposition to identify generators that contribute in each oscillation mode is introduced. Measures based on singular value decomposition for controllability and observability for every mode are described and the selection of the best location for the installation of the PSSs is done according to these measures. The proposed methodology is designed to use the system transfer function. Studies illustrate the effectiveness of the proposed technique.
