Optimal placement of power system stabilizers: Simulation studies on a test system

The power system stabilizer (PSS) is important to quickly damp the inter-area oscillations. From the economic point of view and to avoid redundancy, it is desired, not to employ PSS on individual generators to overcome the problem of inter-area and local mode oscillations. The eigenvalue analysis of the power system for various areas is used to determine the inter-area and local mode frequencies and participation of the generators. It is also important to identify the generator that shall be installed with PSS. A simulation study on well-adopted test system is carried out, with various possibilities, to determine the optimal placement of the PSS. The observations of the certain analysis are helpful in determining the PSS placement and are presented in the paper.
