Abstract
A grid connection control method of an energy storage apparatus, an energy storage control unit, an energy storage system, and a storage medium are provided and relate to the field of energy storage technologies, where the method includes: sequentially controlling energy storage units of energy storage sub-modules to be connected to corresponding voltage-sharing capacitors in a state in which a main energy transmission circuit is disconnected from a direct-current bus, so as to make the energy storage units pre-charge the corresponding voltage-sharing capacitors; and controlling the main energy transmission circuit to be connected to the direct-current bus under a condition that the voltage-sharing capacitor of each energy storage sub-module meets a voltage-sharing capacitor pre-charge completion condition.
