It comprises the following steps: constructing an evaluation index system of a dynamic grouping technology, and designing a fitness function of a self-adaptive longicorn whisker algorithm; constructing a self-adaptive step size formula of a self-adaptive longicorn whisker optimization algorithm; applying a self-adaptive longicorn algorithm to optimize a forced updating threshold value of a dynamic grouping technology; determining an automatic update period of a dynamic grouping technique; grouping the battery units, determining frequency modulation power instructions of three battery packs in the energy storage power station by using a dynamic grouping technology, further determining the frequency modulation instruction of each battery unit, and enabling the battery units to respond. The forced updating threshold is searched by using the self-adaptive longicorn whisker optimization algorithm, so that the extremely poor state of charge of the battery unit after the response is finished is reduced, and the schedulable potential of the energy storage power station in the next scheduling period is improved; the action times of the energy storage system are reduced, and the running economy of the energy storage system is improved.)
