In Japan, keeping stability became critical in the interconnected system, because long-term low damping oscillations in multi-regional power systems (about 0.3Hz to 0.5Hz) arise in large-scale power system interconnections. And the oscillations have been the subject for studies in fields of operation, control, and devices by the many power system utilities. To analyze and solve the problem of low-frequency oscillation phenomena, a method is presented to find the best allocation and to design power system stabilizers (PSSs) for damping inter-area power oscillations. In this paper, allocation of PSSs in an interconnected power system with inter-area modes has been determined by an eigenvalue analysis, and PSSs for the allocated generators have been designed by a frequency response method. Dynamic simulations using a 10-machine power system model are presented in order to show the effectiveness of the PSSs designed according to the proposed method.
