A voltage control device includes a fluctuation calculating unit that calculates voltage tolerance, which is a difference between a voltage measured by a voltage control apparatus and a proper voltage upper limit value or a proper voltage lower limit value, and voltage sensitivity, which is a ratio of a fluctuation amount of active power and a fluctuation amount of the voltage, a change-request-information generating unit that generates information for requesting a change of a limit value of a control target range of other voltage control devices, a change processing unit that performs a change of a limit value of a control target range of the voltage control device according to content of the change request information, and a communication processing unit that transmits the change request information to the voltage control devices other than the voltage control device. The change request information includes information indicating voltage tolerance and voltage sensitivity.
