  "textContent": "This application discloses examples of an energy storage system, a power conversion system, and a method for optimizing primary frequency modulation. In one example, when the power conversion system determines that a state of charge (SoC) value of a target energy storage battery does not meet a target SoC value and determines that a present frequency of a power grid falls within a frequency modulation constant band, the power conversion system determines, based on a preset mapping relationship between a SoC value and an active power, a first specified active power value corresponding to the SoC value of the target energy storage battery, and controls, based on the first specified active power value, the target energy storage battery to be charged or discharged, so that the SoC value of the target energy storage battery can reach the target SoC value.",
