Modularized energy storage converter, control method and device and electronic equipment

The invention discloses a modular energy storage converter, a control method and device and electronic equipment. The control method of the modular energy storage converter comprises the following steps: determining whether a fault exists in a current energy storage converter unit or not; when the energy storage converter unit has no fault, a competition host signal is sent out; confirming a host according to the plurality of competition host signals; the host obtains the total required power, the charge state of each energy storage unit and the efficiency curve of each energy storage unit; the host determines the to-be-accessed/to-be-cut-out number of the energy storage units through the total required power and the efficiency curve of each energy storage unit; and according to the charge state of each energy storage unit, controlling the energy storage units corresponding to the to-be-connected number/to-be-cut-out number to be connected into/cut out of the power grid.
