Abstract
It is possible by means of a system simulation device to extract a disturbance mode wherein multiple accident conditions are assumed and to determine control parameters, but when the number of accident conditions increases, a threshold value pertaining to a divergence constant deviates prior to an update period, with the result that an uncontrollable disturbance mode appears. In order to solve this problem, the present invention is a power system stabilization system for determining control parameters for a control device connected to a power system, the power system stabilization system equipped with: a disturbance mode prediction unit for predicting a disturbance mode of a power system on the basis of operation information and an assumed system configuration for the power system; a post-control parameter update period prediction unit for predicting an update period for a post-control parameter in post-control after a disturbance has occurred; a threshold value setting unit for setting a threshold value pertaining to a divergence constant on the basis of the disturbance mode and the update period for the post-control parameter; and a control parameter determination unit for determ…
