Disclosed is a micro-grid control method for communication-line-free interconnection based on frequency shift control. When a micro-grid runs in an off-grid mode, communication-line-free interconnection micro-grid control is realized with the aid of a power frequency signal of a voltage source, by use of a frequency shift control technology and by taking a frequency signal as a means of communication. No MGCC is needed, and an energy storage device is connected in parallel with DGs autonomously. Specifically, when a micro-grid runs in an off-grid mode, a virtual synchronous generator technology is used in main energy storage.
