According to the present invention, power supplied from the power system of a voltage control device can be distributed to a plurality of power receiving system nodes. The voltage control device comprises: a management server including a predicted voltage calculation unit which receives continuous power data from power receiving system nodes in real time and calculates the predicted voltage of the power receiving system nodes, or an adjusted voltage calculation unit for calculating an adjusted voltage for conservation voltage reduction (CVR); and a voltage adjustment unit for receiving the adjusted voltage and controlling the voltage of the power receiving system nodes. The power receiving system nodes of the voltage control device may include at least one among an electric vehicle charger, a switchboard for controlling the voltage of the electric vehicle charger, or a charging station equipped with a plurality of electric vehicle chargers. Therefore, the voltage control device can predict the charge amount of an electric vehicle charging state or power usage thereof and adjust the voltage to stabilize the voltage of the electric vehicle charging station that varies according to customer distribution or over time and to obtain a CVR effect.
