Advancements in Grid-Forming Technology and Power System Stability

The field of power systems is witnessing significant developments in grid-forming technology and its impact on system stability. Researchers are focusing on quantifying grid-forming behavior, analyzing the interaction between grid-forming and grid-following converters, and developing novel control schemes to enhance system stability. The introduction of new metrics, such as the Forming Index, and the development of decentralized stability criteria are notable advancements in this area. Additionally, the integration of demand response and short-circuit current constraints into unit commitment models is being explored to ensure stable system operation. Noteworthy papers in this area include: Quantifying Grid-Forming Behavior, which proposes a novel metric to quantify a converter's response to grid voltage fluctuations. Dispatchable Current Source Virtual Oscillator Control Achieving Global Stability, which introduces a novel control scheme for grid-following converters that ensures global stability. Analytical Framework for Assessing Effective Regional Inertia, which proposes a novel formulation of effective regional inertia that accounts for system topology and spatial distribution of inertia.
