Abstract
The dynamical behavior of temperature is becoming a critical design consideration for the Modular Multilevel Converter (MMC). Investigation of an advanced control structure for Grid Connected-Modular Multilevel Converter (GC-MMC) is proposed in this paper. To achieve this goal, an non-linear model of MMC regarding considering of negative and positive sequence components with thermal dynamics has been presented. Then, due to existence of unbalance voltage faults in distribution grid, non-linarites and uncertainties in model, adaptive robust current controller which is composed of sliding mode and fuzzy control, is developed for GC-MMC. Finally, numerical results are given in order to show the dynamic performance of GC-MMC prototype under normal and unbalanced fault conditions. They illustrate the proposed current controllers could keep the MMC stable under different conditions and thermal performance of MMC is given.
