Decentralized Control of Parallel-connected Inverters to Achieve Proportional Load Sharing with a Fast Response and Robustness

Abstract

In this paper, we propose a new decentralized control method to achieve proportional load sharing which maximizes an output power of the parallel-connected inverters. By using this method, we can simultaneously obtain the fast response and robustness for proportional load sharing against the disturbances and the model errors. To verify the validity of the proposed method, we also show the simulation result of proportional load sharing and we analyze the steady state and stability of the closed loop system.
