The embodiment of the invention discloses an energy storage multi-cabinet management method, device and system. The management method comprises the following steps: receiving a warning message of a broken-down electric cabinet in a battery electric cabinet array; determining that the battery electric cabinet array is not in a loaded state at present; and quitting the broken-down electric cabinet from the battery electric cabinet array. The energy storage multi-cabinet management method and device which are provided by the embodiment of the invention have the advantages that only the broken-down electric cabinet is quitted from the battery electric cabinet array when the broken-down electric cabinet appears in the battery electric cabinet array of a battery energy storage system, the wholebattery energy storage system does not need to stop running, running reliability of the battery energy storage system is greatly improved, and stability of the battery energy storage system can be guaranteed when the broken-down electric cabinet quits from the array.
Description
technical field [0001] The invention relates to the field of energy storage technology, in particular to an energy storage multi-cabinet management method, device and system. Background technique [0002] The battery energy storage system can effectively adjust the changes in grid voltage parameters caused by new energy power generation and electric vehicle charging, and solve the randomness and volatility problems of new energy power generation and electric vehicle charging. In view of the important role played by large-scale energy storage systems in the grid, the energy storage system needs to have the ability to provide uninterrupted discharge and storage for the grid. [0003] In order to facilitate the placement, repair and maintenance of the battery, the energy storage unit is mostly realized through the battery electric cabinet, and multiple battery electric cabinets are connected to form an array, realizing the energy storage device in the battery energy storage sys...
