Overvoltage suppression method and system of new energy transmission system, and storage medium

The invention discloses an overvoltage suppression method and system for a new energy transmission system and a storage medium, and the method comprises the steps: building an electromagnetic transient simulation model according to the equipment parameters of the new energy transmission system, and determining the overvoltage exceeding position of the new energy transmission system based on the model; and determining parameters of the overvoltage suppression device according to the most serious overvoltage exceeding position. Secondly, when the suppression device is configured, simulation is carried out according to the installation effects of different positions, the suppression device is installed at the standard exceeding position with the highest overvoltage level, and after the overvoltage level of the system is calculated through model simulation, if the standard exceeding positions still exist, the suppression device continues to be installed at the position with the highest overvoltage in the remainin
