Harmonic Voltage Distortion Damping Method for Parallel-Connected LCL-Type Inverters in Islanded Operation
Leming Zhou,Wu Wenhua,Yandong Chen,Jiang Jie,Zhou Xiaoping,Yang Ling,Zhixing He,Kui Yan,An Luo +8 more
TL;DR: A harmonic voltage distortion damping method is proposed in this paper, which mainly includes a direct output voltage control and the parallel virtual-admittance control that effectively reduces the adverse effect of droop-frequency offset on the quality of the PCC voltage.

Bounded droop controller for parallel operation of inverters
TL;DR: The proposed bounded droop controller introduces a zero-gain property and can guarantee the boundedness of the closed-loop system solution, for the first time, for parallelled inverters feeding generic non-linear/linear loads.
