AI Technical Summary
然而，现有技术这种粗放式的控制方法，忽视了不同电池单元在实时荷电状态（State of Charge，SOC）、健康状态（State Of Health，SOH）、可调空间以及历史累积调频里程上的客观差异
[0052] By introducing a direct control mechanism for battery cells based on frequency regulation mileage, the frequency regulation control of energy storage power stations no longer relies on the average distribution strategy of a single power command, but achieves refined management based on battery lifespan, energy state, and operating load. By combining time-frequency decomposition and multi-dimensional state modeling, coordination can be achieved between millisecond-level frequency regulation response and hour-level energy regulation, taking into account both dynamic performance and energy balance. By coupling the frequency regulation execution process with the lifespan model, thermal management model, and SOC balance logic, adaptive optimization of the energy storage system under different operating scenarios is realized. In addition, the control logic of this application is scalable and can be adapted to heterogeneous battery arrays containing cells from different manufacturers and of different types, thereby significantly improving the controllability, maintainability, and economic operating efficiency of energy storage power stations, and providing a unified direct control strategy foundation for the safe, long-life, and high-quality frequency regulation of large-scale energy storage systems.
