Impacts of grid‐forming inverters on distance protection
IET Generation, Transmission &Distribution, Volume 19, Issue 1, January/December 2025.This paper investigates the impacts of grid‐forming (GFM) inverters on distance protection, with the main objective of providing an improved understanding of the topic. Important interoperability issues are highlighted with simulation results and elaborated upon based on the theory behind the distance relay model and the behaviours of GFM inverters ...

IET Generation, Transmission &Distribution, Volume 19, Issue 1, January/December 2025.In this paper, a current differential protection (CDP) scheme based on cosine compensation coefficient is proposed. ABSTRACT The integration of doubly‐fed induction generators (DFIGs) into wind farms presents significant challenges to current differential protection (CDP). In this study, an adaptive CDP principle for wind farms is proposed.
