Abstract

A system information input means takes in system information and a system state determining means determines states of the system. A component operation state determination means determines operation states of system stabilizing components. A control plan deciding means decides a control plan of the system in consideration of operation states of the system and the system stabilizing components. In deciding the control plan, a swing mode analyzing means firstly analyzes the swing mode at each place of the system on the basis of waveforms of time domain response simulations. Then, a control allotment setting means determines control allotment for each of the system stabilizing components based on the mode analysis and a control parameter setting means control sets the control parameters of each of the system stabilizing components. If plural control plans are obtained, the optimal one is selected based on eigenvalues of dynamics of the system or by evaluating time domain system responses by simulation method. The decided control plan is output to the system stabilizing components by a control plan output means.
