New energy power station AGC and energy storage EMS low-coupling coordination control method and system

The invention discloses a new energy power station AGC and energy storage EMS low coupling coordination control method and system, and belongs to the technical field of power system new energy power generation and energy storage energy management. The system runs in a new energy power station containing energy storage, in a traditional system, AGC is generally used for directly issuing a control instruction to an energy storage EMS, in the method, the power margin needed by energy storage self-adjustment such as a charging and discharging plan of the energy storage EMS needs to be considered, and the AGC needs to be matched with the energy storage EMS in a higher coupling mode. According to the method provided by the invention, the AGC system and the EMS system do not issue control signals and only transmit and collect the measurement data. According to the method, the coupling between the energy storage EMS and the AGC system is reduced, the design complexity and the transformation difficulty of the system a
