Coordinated Primary Frequency Regulation and Grid-Forming Control for Wind Turbine Generators
Meng Chen, Yufei Xi, Lin Cheng +4
Conventional grid-forming (GFM) control strategies often treat the DC source as an unconstrained link, creating mismatches when applied to the wind turbine generators (WTGs). Focus…
Optimal sizing of a hydrogen-based direct reduced iron-electric arc furnace system integrated with methanol synthesis toward zero-carbon steel production
Qiang Ji, Fashun Shi, Lin Cheng +4
The paper develops a fractional‑programming model to optimally size a hydrogen‑based direct reduced iron and electric arc furnace system integrated with methanol synthesis, evaluat…
LCL Resonance Analysis and Damping in Single-Loop Grid-Forming Wind Turbines
Meng Chen, Yufei Xi, Frede Blaabjerg +2
A common assumption in both grid-following (GFL) and grid-forming (GFM) control systems is that they are open-loop (OL) stable in the vicinity of high-frequency resonances. Hence c…
