Modular Multilevel Converter Based Solid State Transformer

Analysis of Modular Multilevel Converter Based Solid State Transformer Implementing Hybrid Control

Abstract

A Solid State Transformer (SST) consists of a high-frequency transformer and power electronic converters.It is relatively a complex system. It requires control in many stages. The control methods vary from topology to topology. In this paper, Modular Multilevel Converter (MMC) topology is used in converter stage. To control MMC, a hybrid control is implemented consisting of a modified sorting algorithm and model predictive control. Using the proposed algorithm, the performance of the system under different grid disturbances has been analyzed.
