The typical micro-grid structure was analyzed. Based on the micro-grid system control characteristics and the different micro-source output power characteristics, the causes of micro-grid system circulation were derived from the view of micro-source output power in island mode. Also, an output power control scheme, which combined the running by micro-source inverters with the running of micro-grid storage devices, was proposed. The combined running can be reasonably regulated by voltage frequency and voltage amplitude self restoration drooping curve, and the output power can not only suppress the production of micro-circulation, but also switch freely between network model and island model. The experiment results verify the effective of the control scheme.
