A power storage system and method of controlling the system is disclosed. The power storage system is connected to a power generation system and a grid. If a remaining amount of power of a battery is insufficient when the grid is in a quasi-normal state, the battery is charged by directly receiving electric power from the grid, and thus electric power is available for the if the grid subsequently goes back into the abnormal state.

Power storage system and method of controlling the same

A power storage system and method are disclosed. The system is connected to a load, a power grid, and a power generation system. When the grid is in an abnormal state, a battery is simultaneously charged with power from the power generation system and used to supply power to the load.

Power storage apparatus, method of operating the same, and power storage system

Provided are a power storage apparatus and a method of controlling the power storage apparatus. The power storage apparatus stores power supplied from a power generation system or a power grid. The power storage apparatus supplies stored power to a load during an electric failure, and supplies stored power to the power grid. The power storage apparatus includes at least one battery cell, a battery management unit coupled to the battery cell, a bi-directional converter coupled to the battery management unit, a bi-directional inverter coupled between the bi-directional converter and the power grid, and a central controller controlling the operations of the bi-directional converter, the bi-directional inverter, and the battery management unit. An uninterruptible power supply (UPS) function may be performed to stabilize the power storage system including the power storage apparatus.

Apparatus for storing power and method of controlling the same

An energy management system includes: a first interface configured to receive a first power from a power generation system; a second interface configured to couple to the power generation system, a power grid, and a storage device, and to receive at least one of the first power from the power generation system, a second power from the power grid, or a third power from the storage device, and to supply a fourth power to at least one of the power grid or a load; and a third interface configured to receive the third power from the storage device, and to supply a fifth power to the storage device for storage.
