The invention discloses an energy storage station power coordination control system architecture. The energy storage station power coordination control system architecture consists of a monitoring system, a coordination controller, an energy storage converter (PCS) and a battery management system (BMS), and a LAN is formed by a switch; the monitoring system can receive remote dispatching AGC and AVC instructions and calculate the power adjustment amount of each PCS, PCS adjustment can further be directly performed on a man-machine interface, and the PCS adjustment amount is transmitted to a coordination controller through an MMS adjustment instruction; the coordination controller can receive the MMS adjustment instruction of the monitoring system, directly convert the MMS adjustment instruction into a GOOSE adjustment instruction and send the GOOSE adjustment instruction to the corresponding PCS, local transient power adjustment can be further performed, voltage and current values of agrid connection point are directly collected, the power adjustment amount of each PCS is calculated based on the grid voltage and the frequency fluctuation, and the power adjustment amount is transmitted to the corresponding PCS through the GOOSE adjustment instruction. The priority of local transient adjustment in the coordination controller is higher than the MMS instruction of a monitoring background. The energy storage station power coordination control system architecture is advantaged in that coordinated power distribution in energy storage power stations is achieved, adjustment consistency is improved, and the overall operational reliability of the energy storage power stations is improved.
