With the rapid development of new energy, the integration of photovoltaics (PV) poses new challenges to power grid stability, particularly in transient voltage scenarios. Existing studies primarily focus on PV systems and inverters, emphasizing static over transient voltage stability, with a scarcity of methods for quantitative evaluation of the latter. This study introduces an assessment method for transient voltage stability in grids with distributed PV, considering their specific access and recovery characteristics. Using PSD Power Tools, the method was validated against traditional simulations for single-node systems and tested on an actual power grid, demonstrating its potential to improve transient voltage stability analysis in clean energy-integrated grids.
