Revisiting the Voltage-Source Behavior: Why Impedance Magnitude of Grid-Forming Converter Rises Near Fundamental Frequency?
Chao Wu, Jinhao Wang, Yong Wang +2
Grid-forming (GFM) converters are generally expected to exhibit low impedance near the fundamental frequency due to their voltage-source behavior. However, an impedance peak and a…
Impedance Reshaping Method of DFIG System Based on Compensating Rotor Current Dynamic to Eliminate PLL Influence
Xiaoling Xiong, Bochen Luo, Longcan Li +2
The phase-locked loop (PLL) used in the doubly fed induction generator (DFIG) can cause frequency coupling phenomena, which will give negative resistance characteristics ofthe DFIG…
On Power Control of Grid-Forming Converters: Modeling, Controllability, and Full-State Feedback Design
Meng Chen, Dao Zhou, Ali Tayyebi +3
The popular single-input single-output control structures and classic design methods (e.g., root locus analysis) for the power control of grid-forming converters have limitations i…
A non-invasive fault location method for modular multilevel converters under light load conditions
Yaqian Zhang, Yi Zhang, Frede Blaabjerg +1
This paper proposes a non-invasive fault location method for modular multilevel converters (MMC) considering light load conditions. The prior-art fault location methods of the MMC…
