Abstract
A centralized voltage controller according to the present invention includes a voltage distribution determination unit that calculates a controlled amount in each of a plurality of voltage controllers on the basis of a measured value of a voltage at each point on a distribution line, a tap position determination unit that determines a change amount of a tap position to be given to each of a plurality of local voltage control units on the basis of the controlled amount, and a tap-change-amount management unit that limits the change amount when receiving, from the local voltage control unit, a limit signal indicating that a tap position in the voltage controller controlled by the local voltage control unit is an upper limit or a lower limit of a settable range.
