Abstract
The power conversion device includes common DC buses, AC buses, DC connection terminals, AC connection terminals, N pairs of distributed power supply connection terminals, N DC/DC converters for transferring power between the common DC buses and the distributed power supply connection terminals, M DC/AC converters for transferring power between the AC buses and the common DC buses, and a control unit for controlling each converter on the basis of a high-order control command. The DC connection terminals are connected to the common DC buses and connected to an external DC power distribution grid, the AC connection terminals are connected to the AC buses and connected to an external AC power distribution grid, and the distributed power supply connection terminals are connected to the DC/DC converters and connected to external DC distributed power supplies.
