Abstract

The invention provides an energy storage system management method and device, an energy storage system and a storage medium. The method comprises the following steps: acquiring cell state data of each energy storage unit in the current energy storage system; wherein the cell state data represents the performance state of each cell in the energy storage unit; determining the maximum output power of each energy storage unit according to the cell state data of each energy storage unit; for each energy storage unit, determining the actual output power of the energy storage unit according to the maximum output power of the energy storage unit and the maximum output voltage of the direct current converter coupled with the energy storage unit; and according to the actual output power of each energy storage unit and the current load power demand, determining the target output power of each energy storage unit, so that each energy storage unit outputs electric energy according to the target output power. The abnormal energy storage unit is prevented from influencing the energy storage system to execute the electric energy output task, the task coordination distribution among the plurality of energy storage units is realized, and the stability of the output power of the whole energy storage system is improved.

Description

technical field [0001] The present application relates to the technical field of energy management, and in particular to an energy storage system management method, device, energy storage system and storage medium. Background technique [0002] At present, the increasing demand for electricity for products such as electric vehicles has promoted the innovation and development of battery energy storage technology. [0003] In the existing technology, battery energy storage technology generally adopts the method of connecting batteries in series and then paralleling them. Multiple sets of batteries are connected in parallel to form an energy storage unit. An energy storage system includes multiple energy storage units, and the energy storage units are directly connected to the The DC bus of the high-power converter uses the energy storage unit as the smallest unit for power output to output power. [0004] However, during the use of the energy storage system, abnormalities suc...
