Abstract: An energy storage cabinet includes a battery rack and a power conversion system. A switch unit is connected between a battery unit and the power conversion system. A first end of the power conversion system is connected to a bus. When an energy storage cabinet in the energy storage system is started, a voltage at the first end of the power conversion system is greater than a first preset voltage. The power conversion system in the to-be-started energy storage cabinet may obtain, through the first end, a voltage output by the started energy storage cabinet, convert the voltage into a target voltage, and then supply power to the start unit. After obtaining the power, the start unit controls the switch unit to be turned on. The battery unit may output stored electric energy through the power conversion system, to start the energy storage cabinet.

Abstract: A method includes: performing one or more adjustments on a filter parameter based on battery information of the ESS that is at a first control moment, and performing one or more times of power filtering by the filter, until a power fluctuation rate determined based on a power obtained through filtering is less than or equal to a preset threshold; and determining, based on the power obtained through filtering, a given power of the ESS that is at the first control moment. During smooth control of a power, a relationship is established between battery information and a filter characteristic, so as to prevent a battery from quickly reaching a fully charged state or a fully discharged state.
