Universal Interoperable Control Framework for Inverter-Based Resources

The rapid proliferation of inverter-based resources (IBRs), including both grid-following (GFL) and grid-forming (GFM) topologies, presents significant stability challenges for modern power systems. These challenges are exacerbated by the lack of industry standards for collaborative IBR design, forcing reliance on complex, project-specific modeling and simulations that often fail to guarantee stability across diverse operating conditions. This limitation impedes the seamless, large-scale integration of distributed energy resources (DERs). This presentation rigorously examines interactions within IBR-dominated grids. A novel specifications-based framework is proposed, leveraging time-scales separation to systematically manage and mitigate adverse interactions. As part of this framework, new control techniques designed to achieve robust, stable performance for GFM IBRs will be discussed. Additionally, the presentation addresses the parallel trend of increasing high-voltage DC (HVDC) transmission, which introduces new challenges in stabilizing coupled AC-DC systems. Preliminary research findings will be presented to explain a few of these emerging stability and control challenges, paving the way for future investigations in this critical area.
