This paper presents the performance analysis of a high- voltage direct current (HVDC) transmission system using voltage source converters in modular multilevel topology against lightning. Therefore, several simulations were carried out using the PSCAD/EMTDC software to evaluate the transient response of the converters at both terminals and validate the effectiveness of using metal-oxide surge arresters, commonly used in alternating current (AC) systems and HVDC systems based on line-commutated converters. Furthermore, the use of these devices is not approached in the classic and recent technical literature, which makes the contribution of this research original. The results reveal that the correct sizing and location of the surge arresters promote their proper operation, in addition to pointing out that the overvoltage generated by the incidence of lightning on the AC side does not propagate to the Direct Current side.
