Abstract：To address the voltage over-limit and curtailment issues caused by the high proportion of

photovoltaic（PV）integration into distribution networks，a grid-forming energy storage preventive voltage control

strategy based on voltage sensitivity was proposed. The core of the strategy lies in transforming the "passive

remediation" of voltage over-limit into "active prevention". The strategy is based on the voltage sensitivity matrix

and PV output prediction，and it assesses the risk of voltage over-limit in advance. If there is a risk of over-limit，a

preset charging power curve will be actively issued to the grid-forming energy storage before the over-limit occurs，

allowing it to reserve safety margin for the system by absorbing active power in advance. Simulation verification in

Matlab/Simulink show that this strategy not only effectively prevented voltage over-limit but also achieved zero

curtailment and reduced the number of energy storage actions，significantly enhancing the voltage security level and PV absorption capacity of the distribution network.
