Abstract

Abstract : Here, a methodical research on the stability and response of a converter‐based generation model is conducted, focusing on the accompanying effects of a system split scenario in the (European) electricity transmission network. The purpose of this research is to analyse the behaviour of a generic but detailed model in case of extreme contingencies. In particular the focus is set on reduced short‐circuit power, high rates of change of frequency, and sudden voltage phase jumps at the point of common coupling (PCC). These effects are analysed by means of electromagnetic transient (EMT) simulations. In addition, the stability of the converter control is evaluated qualitatively. For the investigations carried out here, a single reduced wind turbine model with full‐size converter is used focusing on the interactions with the accompanying phenomena of a system split. The results show that reduced short‐circuit power as well as a large and sudden voltage phase jumps can be potential reasons for the converter system to disconnect from the grid.
