Power electronics converters will play a crucial role in power grid expansion. Superior advantages offered by MMC make it the most popular candidate amongst various converter topologies. However, due to a large number of components installed within MMC, reliability analysis is an unavoidable task that needs to be carried out to maximize the MMC's availability and positively affect the overall performance of the power system. To this end, applying redundancy at the converter level is one of the solutions to increase the reliability of the MMC. In this paper, the reliability of the MMC is evaluated during its useful lifetime according to various applied redundancy strategies. At the same time, it is proposed that optimal-decision making in redundancy strategy depends on the failure rate of which components are considered. It will be presented that the superiority of the applied redundancy can vary.
