The invention relates to the technical field of flexible interconnection device control, in particular to a control method and device for an inverter in a flexible interconnection device and a storage medium, and the method comprises the following steps: building a model-free current prediction robust control dynamic model of the inverter; establishing a model-free current prediction robust control evaluation function of the inverter; traversing all control inputs of the system, and calculating corresponding evaluation function values; and selecting the candidate item with the minimum evaluation function value as the control input of the system, and applying the candidate item to the flexible interconnection device. According to the invention, through setting the model-free current prediction robust control dynamic model and the evaluation function, the evaluation function value corresponding to each switch state can be calculated, and the switch state corresponding to the minimum evaluation function value is
