December 6, 2021 – Dr Zhida Deng

Dr Zhida Deng presented the paper ‘Comparison between Ideal and Frequency-dependent Norton Equivalent Model of Inverter-Based Resources for Harmonic Studies’ at the ISGT Asia Conference. The title of the session was ‘Power quality and power electronic applications – 1’.  

This paper has been co-authored with National Grid. The paper compares various approaches to modelling inverter-based resources, namely, the ideal Norton Equivalent Model, the Norton equivalent model with a fix impedance, and the Norton equivalent model with a frequency-dependent impedance.
