Adaptive voltage unbalance compensation based control strategy for islanded microgrid

Jinman Luo, Haiji Wang, Liyuan Liu

IEEJ Transactions on Electrical and Electronic Engineering > 16 > 11 > 1470 - 1478

In order to compensate voltage unbalance at the point of common coupling (PCC) for the islanded microgrid, a novel strategy based on PCC negative‐sequence voltage feedforward is proposed. Through the PCC negative‐sequence voltage feedforward, a virtual voltage source is added to the DG terminal at the negative‐sequence. Then, the effective impedance between the distributed generation (DG) unit and...

Xianhua Zhao, Liyuan Liu, Cuixia Li, Hua Li

Brazilian Journal of Botany > 2019 > 42 > 2 > 261-269

Grape pruning may lead not only to some physical damages to the xylem vessels but also to the tylose blockage in these vessels. However, there is little information on vessel lumens blockage by tylose decreasing the original capability of sap flow transportation. In present studies, to elucidate the effect of tyloses on both water transport during xylem development and variations in hydraulic conductance...

Impact of gas adsorption-induced coal damage on the evolution of coal permeability

Wancheng Zhu, Liyuan Liu, Jishan Liu, Chenhui Wei, more

International Journal of Rock Mechanics and Mining Sciences > 2018 > 101 > C > 89-97

During the injection of CO₂ into coalbed for geologic sequestration, CO₂ is likely both adsorbed and dissolved in coals, and swells them slightly. When coal is swollen due to the adsorption and dissolution, the induced strain is relieved as the coal structure rearranges to a lower free energy state, causing coal damage and resulting in permeability change. This adsorption- and dissolution- induced...

Liyuan Liu, Wei Chen, Jiangtao Shi, ChengShan Li, more

Fusion Engineering and Design > 2017 > 124 > C > 86-89

As the only high-temperature superconductor (HTS) that can be made into round wire without anisotropy, Bi-2212 round wire holds significant potential for applications as CICC (cable in conduit conductor) for superconducting magnets in fusion reactors. However, Bi-2212 is brittle and sensitive to strain which leads to a low mechanical performance. The effort on studying the impact of strain on the...
