  "textContent": "The present invention discloses a method and system for participating in grid frequency regulation within full range of charging and discharging of energy storage, comprising: collecting grid operation power and frequency data, and constructing a full-range droop coefficient; setting constraints of upper and lower limits of a frequency deadband, obtaining an actual output power command value based on the constraint function constructed from a theoretical power command value and a rated charging and generating power value, and controlling operation of the grid; and setting a hysteresis interval on the power command of an energy storage system, wherein when the demand of the grid exceeds the upper threshold, the energy storage system switches from the charging mode to the discharging mode; and when the demand of the grid falls below the lower threshold, the energy storage system switches from the discharging mode to the charging mode.",
