Robust Circuit Parameters Design for the CLLC-Type DC Transformer in the Hybrid AC–DC Microgrid
Jingjing Huang,Xin Zhang,Zhikang Shuai,Xinan Zhang,Peng Wang,Leong Hai Koh,Jianfang Xiao,Xiangqian Tong +7 more
TL;DR: A robust circuit parameters design scheme is proposed for the CLLC-DCT and exhibits good power transmission and voltage regulation ability in the hybrid ac/dc microgrid even when its actual inductors/capacitors values vary with the practical power and temperature.
Journal ArticleDOI
Distributed Hierarchical Control of AC Microgrid Operating in Grid-Connected, Islanded and Their Transition Modes
TL;DR: Compared with central-standard hierarchical control, the proposed method only requires local neighbor-to-neighbor interaction with a sparse distributed communication network, and the scalability, flexibility, reliability, and robustness are greatly improved in practical application.
