Summary:The invention provides a control method and device for an energy storage system to participate in primary frequency modulation and a medium. The control method for the energy storage system to participate in primary frequency modulation comprises the following steps: acquiring the current frequency of a power grid; when the difference value between the current frequency of the power grid and the rated frequency of the power grid is greater than a preset frequency deviation, determining inertia output and droop output of the energy storage system according to the battery capacity of the energy storage system and the difference value between the current frequency of the power grid and the rated frequency of the power grid; determining an inertia distribution coefficient and a droop distribution coefficient according to the difference between the current frequency of the power grid and the rated frequency of the power grid; determining the actual inertia output of the energy storage system according to the inert
