Dynamic switching control method of energy storage system and energy storage system

The invention provides an energy storage system dynamic switching control method and an energy storage system, and belongs to the technical field of energy storage batteries. The method comprises the following steps: acquiring a parameter set of each battery cluster in the energy storage system, wherein the parameter set comprises a charge-discharge state and a residual electric quantity of the battery cluster; based on the parameter set, judging whether a target battery cluster meeting a triggering condition of a dynamic switching strategy exists in the plurality of battery clusters or not; and when the target battery cluster exists in the plurality of battery clusters, controlling the connection state of the target battery cluster based on the dynamic switching strategy. Thus, charging cut-out or discharging cut-in of a single battery cluster can be achieved, the problem that control over the battery clusters in the energy storage system is not flexible can be solved, and the safety and operation efficiency
