Control method, apparatus and system for high-capacity integrated type virtual synchronous machine

The invention discloses a control method, apparatus and system for a high-capacity integrated type virtual synchronous machine. The control system for the high-capacity integrated type virtual synchronous machine comprises n groups of energy storage battery backs, n paths of DC/DC circuits, and n paths of DC/AC circuits, wherein each energy storage battery pack is connected with the corresponding DC/DC circuits and DC/AC circuits in sequence; the direct current sides of the DC/AC circuits are connected with a direct current bus in parallel; the alternating current sides of the DC/AC circuits are connected with a transformer in parallel; and the alternating current sides of the DC/AC circuits are connected with n paths of filtering loops. By virtue of the process, the problem of relatively high difficulty in SOC balance control of the high-capacity energy battery is solved. 本发明公开了种大容量集中式虚拟同步机控制方法、装置及系统，其中大容量集中式虚拟同步机系统包括n组储能电池组，n路DC/DC电路，n路DC/AC电路，每个储能电池组依次连接对应的DC/DC电路和DC/AC电路，DC/AC电路的直流侧并联连接直流母线，DC/AC电路的交流侧并联接
