A method for collaborative control of dual inverters in a microgrid includes performing isolated grid detecting on a microgrid to determine the operation state of the micro-grid; detecting whether a load of the microgrid is a balanced load or an unbalanced load; detecting whether the load contains harmonics, and determining a class of the load; determining a working condition type of the microgridaccording to an operating state of the microgrid and a category of the load; controlling the output current of the dual converters according to the working condition type of the microgrid, the dual converters comprising a first converter and a second converter. The power distribution can be effectively controlled, the power supply quality can be improved, and the service life of the battery can be prolonged.
