High-voltage ride through module of energy storage system and control method thereof

The invention discloses a high-voltage ride through module of an energy storage system and a control method of the high-voltage ride through module. The high-voltage ride through module comprises an MOS tube unit, a driving unit, a power supply unit, a sampling unit and a control unit. One end of the switch unit is connected with the anode of the battery, and the other end is connected with the DCside of the energy storage converter; the power supply unit takes power from the energy storage system to provide electric energy for the driving unit and the sampling unit; wherein the driving unitis used for driving the switch unit to work, and the sampling unit detects power grid voltage and grid side current in real time and feeds back the power grid voltage and the grid side current to thecontrol unit; the control unit is used for sending a control instruction to the driving unit according to feedback of the sampling unit to control the switch unit to be turned off. The module is simple and convenient in impleme
