The invention pertains to the control technology of microgrid energy storage systems, particularly to a hierarchical distributed control method and device for microgrid cluster with heterogeneous batteries. This method includes primary droop control, two-layer voltage regulation control, and two-layer power management control. The incremental cost of heterogeneous batteries is physically defined as the partial derivative of energy loss with respect to output power. A cooperative control method for the incremental cost of multiple heterogeneous battery units is proposed, which can achieve economic power distribution among multiple heterogeneous battery units while meeting the constraints of charging/discharging power, SoC, and power balance. This invention's method integrates battery types where charging efficiency is tied to charging power with those where charging efficiency is connected to SoC, ensuring ease of expansion. Even with the introduction of a new battery type in the microgrid cluster, the method continues to be effective.
