Grid forming (GFM) control is an emerging technique for power electronic devices that plays a crucial role in the integration of inverter-based resources (IBRs) such as battery energy storage systems (BESS), solar, and wind into the power grid. GFM inverters are designed to help maintain the frequency and voltage of AC power grids, providing a stable and reliable power supply. As the future power grid shifts towards a higher penetration of IBRs, the use of grid forming inverters is becoming increasingly important. This presentation introduces several types of commonly used GFM voltage source converter (VSC) models, including droop control, virtual synchronous generator, and synchronverter, which have recently been developed in RSCAD FX. Additionally, the presentation demonstrates how GFM VSC examples can be conveniently modified and implemented in various real-time simulation applications, such as BESS, renewables, microgrids, and HVDC transmission.
