Abstract
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.
Claims22
An energy management system comprising:
- 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,
- wherein the third interface is further configured to receive at least one of the first power converted by the first interface or the second power converted by the second interface.
