Abstract
To develop renewable energies, increasing inverter-based resources (IBRs) are integrated into the grid. In IBRs, multiple inverters are often connected to the point of common coupling (PCC) in parallel and adopt the phase-locked loop (PLL) for maintaining the synchronism of the injected current. In state-of-the-art research, the power exchange between inverters and the grid during the transient process has been well studied, revealing the transient instability mechanism. However, the interactions among inverters, which also affect the transient stability, are not fully taken into consideration. This paper analyzes the system transient stability through the modeling of an n-parallel PLL-synchronized inverters system, and then proposes an optimized coordination control method to improve the system transient stability. Finally, a 3-parallel PLL-synchronized inverters simulation model is established and tested to verify the theoretical analysis and proposed method.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
