| description | While virtual inductance in grid-forming control effectively reduces inrush current, it negatively impacts transient stability. This study proposes a synchronous loop control strategy incorporating an adaptive adjustment mechanism to improve power angle stability and dynamic response performance in grid systems. Initially, the transient stability mechanism under voltage sag is analyzed, revealing its dependence on both the active power reference value and the Point of Common Coupling voltage. Subsequently, phase compensation is applied in the active power loop to lower the active power reference value, while voltage feedback is utilized in the reactive power loop to enhance the Point of Common Coupling voltage. Furthermore, an adaptive adjustment mechanism dynamically optimizes the equivalent power reference value by regulating phase compensation coefficient, effectively minimizing power angle oscillation amplitude. Moreover, the inertia and damping parameters are tuned to strengthen frequency dynamic response capability. Finally, the stability of the proposed control strategy is rigorously validated through Lyapunov function analysis. Simulation results validate that the proposed strategy significantly enhances transient stability and dynamic performance under voltage sag conditions. |
