分布式电池储能系统(BESS)的协调控制是储能应用中的关键问题。针对聚合多样性BESS参与自动发电控制的应用场景，文中首先提出了基于BESS集群荷电状态(SOC)的集群能量平衡反馈控制结构；然后针对充放电损耗与电池老化建立了BESS的服务成本模型，定义了每个控制周期的边际损耗成本和边际老化成本，据此提出了基于市场机制的无需迭代的控制方法，实现了控制目标在BESS集群内的实时最优分配；最后在仿真中对比了BESS聚合器的多种SOC控制方法以及BESS的多种协调控制方法，验证了所提出方法的有效性。

One essential problem of battery energy application is the coordinated control of distributed battery energy storage systems(BESS). To study the aggregation of different BESS participating in automatic generation control, a feedback control method of the state of charge(SOC)is firstly proposed. Secondly, a cost model for the charge and discharge loss and battery aging is established. Thirdly, by defining each control cycle's marginal loss cost and marginal aging cost, a market-based control method without iteration is proposed to achieve the real-time optimal power allocation within BESS aggregator. Finally, a simulation analysis on the effectiveness of several SOC control methods and coordinated control methods of BESS is implemented. The results verify the effectiveness of the proposed method.
