Abstract
A power distribution apparatus may comprise a converter configured to perform DC-DC conversion between a battery and a power conversion system; and a controller configured to set a droop curve for controlling an output of the converter based on a state of each battery, wherein the converter is configured to receive and store information on the droop curve set by the controller, detect a voltage change in a DC link between the power conversion system and the converter, the voltage change being caused by a start of a charging or a discharging operation, and control the output of the converter based on a detected DC link voltage and the droop curve.
