Identification of optimum sites for power system stabilizer applications

Many existing methods of identifying the optimum sites for installing power system stabilizers (PSSs) in multimachine systems are restricted to (1) the sequential PSS application, which considers the enhancement of damping of just one critical electromechanical mode at a time; (2) the eigenstructure analysis of the open-loop system, which does not take the control matrix (i.e. the B matrix in the linearized model x=Ax+Bu for power systems) into consideration. A method of identifying the optimum sites for installing power system stabilizers is described that can identify the optimum sites for installing PSSs so that several electromechanical modes are damped out simultaneously and that take both the eigenstructure of the open-loop system and the control matrix into consideration. >
