This paper investigates the capacity allocation problem when the storage battery assists the primary frequency regulation of the power grid using the antlion

An energy storage system equipped with a new energy station can smooth the fluctuation of output power and undertake the frequency regulation obligation of the new energy unit. Nevertheless, the energy storage may cause an insufficient active power reserve of the frequency modulation system if it considers only the single stabilizing fluctuation condition.

The results show that when the lithium-ion energy storage power station is applied to the primary frequency regulation condition, the response time of the converter is 60—80 milliseconds, and the overload capacity of the converter can reach 150% within 30

As can be seen from Fig. 1, the digital mirroring system framework of the energy storage power station is divided into 5 layers, and the main steps are as follows: (1) On the basis of the process mechanism and operating data, an iteratively upgraded digital model of energy storage can be established, which can obtain the operating
