摘要：

This paper shows the feasibility of a novel decentralized control scheme for the grid-tied ac-stacked photovoltaic (PV) inverter architecture. The proposed decentralized control scheme with low-bandwidth communications requirements enables a fully distributed PV inverter architecture. Detailed modeling and theoretical analyses will be provided to support the existence of such decentralized control scheme. Simulation and experimental results on a representative laboratory-scale prototype will be presented under symmetrical and asymmetrical conditions as well as 10% grid voltage sag to show the effectiveness of the proposed control scheme in different operating conditions.
