ENERGY STORAGE CONVERTER, CONTROL METHOD AND DEVICE THEREFOR, AND COMPUTER READABLE STORAGE MEDIUM

An energy storage converter, a control method and device for the energy storage converter, and a computer readable storage medium are provided. The control method includes: obtaining an operation state of a power grid; under the condition that the power grid operates in a normal state, controlling the energy storage converter to operate in a grid-connected mode; and under the condition that the power grid operates in an abnormal state, controlling the energy storage converter to operate in an island mode. In the grid-connected mode, the energy storage converter uses active power and reactive power decoupling control. In the island mode, the energy storage converter uses virtual magnetic flux control.
