This paper is concerned with cooperative control for distributed grid-connected PV system. A two-layer control strategy is adopted, while the upper layer is a cooperative control to organize all the PV units to work cooperatively with given power ratio and the lower layer is a tracking control for a single PV unit. The information communication between PV units is realized through the ring communication structure applied in the upper layer. By using a mixed sensitivity approach, the controller for each single PV unit has strong robustness. The effectiveness of the proposed method is demonstrated by simulation in Matlab.This paper is concerned with cooperative control for distributed grid-connected PV system.
