PROBLEM TO BE SOLVED: To provide a voltage control method of a power distribution system, which can easily improve voltage unbalance and voltage deviation in the power distribution system.SOLUTION: A multi-phase AC voltage is applied to distribution lines. An individual controller individually adjusts multi-phase inter-line voltages of the distribution lines on the basis of individual control commands. A measuring instrument measures physical quantities about currents or voltage in the distribution line, as measurement information. In a step S245, the individual control commands are determined on the basis of the measurement information so that a voltage unbalance rate of the distribution lines is lower than a prescribed value. After the execution of the step S245, the individual control commands are calculated on the basis of the measurement information so that multi-phase inter-line voltages are within a prescribed range, under the condition that the individual controller adjusts the multi-phase inter-line voltages in the same direction by the same amount. |
