Abstract
The main objective of this paper is to propose a decentralized control approach for active and reactive power control of grid-tied cascaded H-bridge PV inverter architecture. The decentralized controller allows fully distributed architecture both in terms of control and physical implementation of a PV system, resulting in higher reliability and potentially lower cost. The proposed control approach not only maintaining the balance of the system but also by sending supervisory commands to only one inverter minimizes the required communications for controlling active and reactive power. Detailed modeling and analysis are provided to show the feasibility of the proposed decentralized approach. The decentralized control scheme is verified by real-time hardware-in-the-loop setup.
