The paper describes the concept of potential application of ACS6080-based grid simulator from ABB and its newly introduced current source mode, to support the testing of grid forming mode (GFM) converters with focus on their island conditions. The obtained simulation results demonstrate promising performance and provide a base for future investigations involving real equipment, towards approaching the viable alternative to conventional test setups, enabling a broader scope and greater diversity of GFM generation units conformity testing.
