Abstract: An energy storage valve operation control method and apparatus, an energy storage system, a computer device, a storage medium, and a computer program product. In a case that an energy storage valve needs to exit operation, a branch current of the energy storage valve is gradually controlled to reduce. During this process, a power variation of the energy storage valve is acquired in real-time and the acquired power variation is sent to a sending-end voltage source converter valve, enabling the sending-end voltage source converter valve to adjust its output power based on the power variation of the energy storage valve at any time, thereby maintaining stable output power of the sending-end voltage source converter valve. Ultimately, when the branch current decreases to satisfy a preset current condition, the energy storage valve is disconnected from a grid.
