Decentralized Parametric Stability Certificates for Grid-Forming Converter Control
Verena Häberle, Xiuqiang He, Linbin Huang +2
We propose a decentralized framework to analytically guarantee the small-signal stability of future power systems with grid-forming converters. Our approach leverages dynamic loop-…
Quantifying Grid-Forming Behavior: Bridging Device-level Dynamics and System-Level Strength
Kehao Zhuang, Huanhai Xin, Verena Häberle +5
Grid-forming (GFM) technology is widely regarded as a promising solution for future power systems dominated by power electronics. However, a universally accepted definition of GFM…
Equilibrium-Free Contraction Stability Analysis for Grid-Forming Converter-Based Microgrids
Shijie Peng, Xiuqiang He, Xi Ru +1
Renewable-driven microgrids dominated by grid-forming (GFM) converters are subject to persistent power fluctuations, making equilibrium-known stability assessments restrictive. Thi…
Quantifying Grid-Forming Behavior: Bridging Device-Level Dynamics and System-Level Strength
Kehao Zhuang, Huanhai Xin, Verena Häberle +3
Grid-forming (GFM) technology is widely regarded as a promising solution for future power systems dominated by power electronics. However, a precise method for quantifying GFM conv…
Next-Generation Grid Codes: Towards a New Paradigm for Dynamic Ancillary Services
Verena Häberle, Kehao Zhuang, Xiuqiang He +3
This paper introduces a conceptual foundation for Next Generation Grid Codes (NGGCs) based on stability and performance certificates, enabling the provision of dynamic ancillary se…
Dispatchable Current Source Virtual Oscillator Control Achieving Global Stability
Kehao Zhuang, Linbin Huang, Huanhai Xin +3
This work introduces a novel dispatchable current source virtual oscillator control (dCVOC) scheme for grid-following (GFL) converters, which exhibits duality with dispatchable vir…
