Micro-grid, combined with distributed generation(DG), which reduce the impact on the grid, combines the advantages of each proposed distributed generation units. It can operate in islanding mode and grid-connected mode: In grid-connected mode, it works in current-mode. While in islanding mode,it needs to maintain voltage and frequency stable.This paper based on the stratified contral structure, propose a new controller, not only it can suitable for the system’s method smooth transformation, but also can weak the transient process effects, so the system’s stability can be improved . Finally, experimental the new controller’s validity and reliability by establishing the experimental platform.
