An energy storage system (100) includes a battery system (200), a direct current link (300), and a controller (105). The battery system includes battery racks (210) that respectively include rack battery management systems (211). The battery racks (210) are divided into a first group (221) comprising at least one first battery rack (210a) including a first battery (213a) and a second group (223) comprising at least one second battery rack (210b) including a second battery (213b), wherein the direct current link (300) is connected to the battery system (200) and the controller (105) determines the operation mode of the battery system (200) from one of a charge mode or a discharge mode. The controller (105) performs a control operation in the charge mode to charge the first battery rack (210a) and not operate the second battery rack (210b), and performs a control operation in the discharge mode to discharge the second battery rack (210b) and not operate the first battery rack (210a). |
