Beschreibung
Zusammenfassung:	The invention discloses a method for controlling charging and discharging of a line energy storage device. The method for controlling the charging and discharging of the line energy storage device includes the steps of determining discharging current value of the line energy storage device, determining charging current value of the line energy storage device, determining charging and discharging voltage of the line energy storage device with actual voltage of a power supply network, the discharging and the charging current value as parameters and according to a specific functional relationship between the charging and discharging voltage value and the parameters of the actual voltage of the power supply network, the discharging and charging current value, instructing the line energy storage device to charge when the said charging voltage is reached, and instructing the line energy storage device to discharge when the said discharging voltage is reached. With the method of the invention, charging and discharging voltage value of the line energy storage device are provided, and thus, the line energy storage device is allowed to be timely charged and discharged when the charging and discharging voltage value are reached, net pressure of the power supply network is further ensured to be stable, and energy is saved.
