Abstract
A direct current bus control system including a direct current bus connecting between an input power supply and a load, including a main stabilizing device including a first charge-&-discharge element and a first power converter, and at least one sub-stabilizing device including a second charge-&-discharge element, a charge element, or a discharge element, and including a second power converter, wherein the first power converter is configured to derive a bus voltage target value according to a power storage amount index of the first charge-&-discharge element, and to bidirectionally pass direct current power, so that the voltage of the direct current bus matches the bus voltage target value, and the second power converter is configured to derive a current target value, and to pass direct current power, so that a current equal to the current target value flows.
