A Virtual Inertia Control Strategy for DC Microgrids Analogized With Virtual Synchronous Machines
Wu Wenhua,Yandong Chen,An Luo,Leming Zhou,Zhou Xiaoping,Yang Ling,Yanting Dong,Josep M. Guerrero +7 more
TL;DR: A virtual inertia control strategy through bidirectional grid-connected converters (BGCs) analogized with virtual synchronous machine (VSM) is proposed to enhance the inertia of the DC-MG, and to restrain the dc bus voltage fluctuation.
Journal ArticleDOI
Sequence Impedance Modeling and Stability Comparative Analysis of Voltage-Controlled VSGs and Current-Controlled VSGs
Wu Wenhua,Yandong Chen,Leming Zhou,An Luo,Zhou Xiaoping,Zhixing He,Yang Ling,Xie Zhiwei,Liu Jinming,Mingmin Zhang +9 more
TL;DR: The voltage-controlled VSG is more suitable than the current-controlledVSG for grid-connected renewable energy generation in an ultraweak grid from the point of view of system stability and experiment results validate the stability analysis.
Journal ArticleDOI
Sequence-Impedance-Based Stability Comparison Between VSGs and Traditional Grid-Connected Inverters
Wu Wenhua,Leming Zhou,Yandong Chen,An Luo,Yanting Dong,Zhou Xiaoping,Qianming Xu,Yang Ling,Josep M. Guerrero +8 more
TL;DR: The stability analysis results show that the TGCI loses stability easily, whereas the VSG still works well without PLL restrictions under an ultraweak grid or with a large number of inverters connected to the grid.
Journal ArticleDOI
Inverter-Current-Feedback Resonance-Suppression Method for LCL-Type DG System to Reduce Resonance-Frequency Offset and Grid-Inductance Effect
Leming Zhou,Zhou Xiaoping,Yandong Chen,Zhipeng Lv,Zhixing He,Wu Wenhua,Yang Ling,Kui Yan,An Luo,Josep M. Guerrero +9 more
TL;DR: An inverter-current-feedback reso-nance-suppression method without additional sensors is proposed to reduce resonance-frequency offset and grid-inductance effect due to its unattenuated damping characteristic under high-frequency bandwidth and a robust ICFRS is further proposed to improve system stability by maintaining a positive resistance regardless of grid- Inductance variation.
Journal ArticleDOI
A Virtual Phase-Lead Impedance Stability Control Strategy for the Maritime VSC–HVDC System
TL;DR: A virtual phase-lead impedance stability control strategy aiming at rectifier station can effectively mitigate the dc-side oscillation of the VSC–HVDC system without affecting the load performance of the inverter station.
