Control method and control system for switching power supply modes of energy storage train

The invention provides a control method and a control system for switching power supply modes of an energy storage train; in the process of switching power supply of an overhead line system and power supply of the energy storage system, a bidirectional DC-DC conversion circuit is controlled to enter the boost chopping voltage-boosting mode, the bus voltage of the train is increased, and the voltage of a train bus is higher than the voltage of a contact network in contact with a pantograph or the voltage of the contact network to be in contact with the pantograph, so that in the power supply mode switching process, no current is transmitted between the contact network and the pantograph, the arc discharge problem occurring at the moment when the pantograph is separated from the contact network is avoided, and the problem that a ground transformer substation is impacted due to sudden load switching caused by the instant contact between the pantograph and the contact network is avoided. 本申请提供一种储能列车切换供电方式的控制方法和控制
