Abstract
A direct-current bus control system is provided for controlling power variation in a DC bus connecting an input power source and a load, including: a main stabilizer including a first charge/discharge element and a first power converter; and a plurality of sub-stabilizers each including a second charge/discharge element, a charge element, or a discharge element, and a second power converter. The plurality of sub-stabilizers include a first sub-stabilizer and a second sub-stabilizer including the charge element. When the voltage of the DC bus is higher than a first charge threshold, the second power converter of the first sub-stabilizer supplies a current equal to a current target value obtained by the second power converter of the first sub-stabilizer from the DC bus to the charge element of the first sub-stabilizer.
