Abstract
With conventional technology, since calculation of system stability is performed regarding all imaginable failure cases for the combinations of all objects to be controlled to determine an object to be controlled, there has been a problem of not being able to determine an object to be controlled in all the imaginable failure cases within a calculation period due to longer calculation time. In order to solve the problem, this apparatus for stabilizing a power system is provided with: an imaginable failure scenario generation unit; a power-flow state generation unit that generates a power-flow state of the power system; a system stability calculation unit that calculates system stability of the power system; a to-be-controlled candidate calculation unit that calculates a candidate object to be controlled for stabilization of the power system; a control table calculation unit that calculates a control table; a system stability calculation requiring/non-requiring state range extraction unit that extracts a state range where stability calculation of the power system is required and a state range where stability calculation is not required; and a system stability calculation requiring/non-requiring determination unit that determines whether or not stability calculation of the power system is required.
