Power system operators around the world are pushing the limits of integrating inverter-interfaced generation from wind and solar to very high levels approaching 100%, including in South Australia, Ireland, the Hawaiian Islands, and Great Britain. These and several others have identified the value of grid-forming (GFM) technology as the key enabler to support this transition. They have integrated several GFM battery energy storage systems to ensure stable operation of their grids, and they are also the front runners in developing preliminary and non-mandatory specifications for GFM resources. On the other end of this spectrum are large power system operators with moderate but ever-increasing levels of inverter-based resources (IBRs) that are still…
