Abstract

Grids are seeing changing SCRs, due to increased power converter penetration. This paper assesses several common small signal modelling techniques of varying computational complexity for their accuracy. Each model is tested for its accuracy limitations in response to a power disturbance for varying grid SCRs and X/R ratios and controller damping for distribution networks.
