Abstract: This direct-current bus control system for controlling power variation in a direct-current bus connecting an input power supply and a load comprises: a main stabilization device including a first charge/discharge element and a first power converter; and at least one sub-stabilization device including a second charge/discharge element, a charge element, or a discharge element and a second power converter. The first power converter is configured to determine a bus voltage target value corresponding to a stored electricity amount index of the first charge/discharge element, and is configured to bilaterally exchange direct-current power between the first charge/discharge element and the direct-current bus in such a way that the voltage of the direct-current bus matches the bus voltage target value. The second power converter is configured to determine a current target value in accordance with a difference between a threshold value relating to charging or discharging of the second charge/discharge element, the charge element, or the discharge element and the voltage of the direct-current bus, and is configured to exchange direct-current power between the second charge/discharge element, the charge element, or the discharge element and the direct-current bus in such a way that a current equal to the current target value flows through the second charge/discharge element, the charge element, or the discharge element.
