Advancements in Grid-Forming Control and Power System Stability

The field of power systems is moving towards greater integration of inverter-based resources, which requires innovative control strategies to ensure stability and efficiency. Recent research has focused on developing advanced grid-forming control methods that can handle current limits, modulation limits, and frequency dynamics. These new approaches aim to optimize power flow, minimize frequency deviations, and enhance overall system resilience. Notably, some studies have challenged traditional industry paradigms, suggesting that current trends may be limiting the potential benefits of inverter-based resources. Furthermore, the application of neural networks and adaptive control strategies has shown promise in improving the stability and performance of power systems. Some noteworthy papers in this area include:

  • The paper on constraint-aware grid-forming control, which achieves fast current limiting while preserving transient stability.
  • The study on modal analysis of core inertial dynamics, which reveals that current industry trends may be constraining the potential benefits of inverter-based resources.
  • The research on small-signal stability oriented real-time operation of power systems, which proposes a control strategy to ensure safe operation with high penetration of inverter-based resources.
