| Summary | Power electronics interfacing renewables, storage, and novel transmission technologies are envisioned to be the cornerstone of tomorrow's resilient and sustainable power systems. While state-of-the-art power converter control can replace grid-forming and grid-supporting functionalities of synchronous machines, their design typically neglects crucial aspects such as unbalanced faults and the interaction between converter protection (e.g., current limiting) and system-level protection. This jeopardizes system reliability and resilience and has already resulted in large-scale system outages and separation events. This proposal is focused on development of a framework that explicitly accounts for current limits, unbalanced conditions, and protection in the control design. The proposed approach will enable reliable and predictable fault-ride through capabilities that do not rely on heuristics, avoid adverse interactions with system protection, and retain the positive impact of grid-forming control on system-level stability when feasible. |
