Abstract
In a power system stabilization device and power system stabilization method, an excess/shortage of control is prevented and an appropriate control suitable for the system state is enabled. A power system stabilization device including a central processing unit in which there is determined, in advance, a device subject to control necessary to maintain stability when an assumed failure in a power system including renewable energy occurs, wherein the central processing unit executes, for each of a plurality of assumed failures, a computation for determining a subject of control necessary to maintain stability at the time of the assumed failure, and determines, in accordance with an output fluctuation scenario for renewable energy pertaining to the weather, the degree of priority of performing a computation for determining a subject of control necessary to maintain stability at the time of each of the assumed failures.
