Abstract
A power system supervisory control apparatus, a power system supervisory control system, and a power system supervisory control method for reducing social cost and improving resilience of a power system are provided. The power system supervisory control apparatus including multiple renewable energy power supplies includes: a system influence degree evaluation section that evaluates a system influence degree when a renewable energy fluctuation or an assumed fault has an influence on the power system by using, as computation conditions, system data for obtaining a state of the power system, renewable energy fluctuation data indicative of a fluctuation of a power generation output, and assumed fault data of an assumed fault in the power system, and calculates system influence degree evaluation result data; a computation condition selection index calculation section that calculates a selection index for the computation conditions; and a condition selection section that selects the computation conditions.
