Abstract: A method of controlling distributed power supplies is provided. In the method of controlling one or more distributed power supplies included in a microgrid, as a feeder flow control mode, an operation mode of a first distributed power supply is set, which is firstly connected to a common coupling point of the microgrid and a main grid. A second distributed power supply is selected, which is different from the first distributed power supply. A next operation mode of the second distributed power supply is determined on a basis of a current operation mode of the selected second distributed power supply and output power of the first distributed power supply. The next operation mode of the second distributed power supply is set as one of the feeder flow control mode or a unit power control mode according to the determined result.
