Optimal allocation and design of power system stabilizers for enhancing the damping of inter-area oscillations in Japanese eastern interconnected power system

Large extended power systems are often characterized by inter-area oscillations, usually spontaneous, which may be caused by small disturbances, such as changes in load, that take place continually. Inter-area oscillations have been the subject for studies in the fields of operation, control, and de...

More Information
Summary:Large extended power systems are often characterized by inter-area oscillations, usually spontaneous, which may be caused by small disturbances, such as changes in load, that take place continually. Inter-area oscillations have been the subject for studies in the fields of operation, control, and devices by many power system utilities in Japan. Power system stabilizers (PSSs) are very effective controllers in enhancing the damping of low-frequency oscillations, since the controllers can increase damping torque for inter-area modes by introducing additional signals into the excitation controllers with which generators are already equipped. Allocation of PSSs has been determined by an eigenvalue analysis, and PSSs for the allocated generators have been designed by a frequency response method. The designed PSSs have been verified in a Japanese power system standard model.
