Design of Multilevel Modular Converter: A Mathematical Model in MATLAB Simulink

The development of various renewable energy generation techniques and distributed generation of electricity due to the increased global energy needs, a robust transmission system for the transfer of power from high generation regions to high demand regions over long distances is the need of the hour. In order to achieve the successful integration of the renewable energy generating systems, HVDC systems are being integrated into the current AC grids. VSC technology has been the recent interest since the advent of semiconductor turn off devices and their inherent advantages. Multilevel Modular Converter is the latest form of VSC type of converters suitable for flexible power transmission with lower insulation transformer, low switching losses, high scalability and high modularity. With the increased capabilities of the converter, accompanies increased complexity in the design and control of the converter. The main aim of this thesis is to build a mathematical model of an MMC that is capable to simulate the working of the MMC with high scalability of the power ratings of the converter with high modularity and establish a relationship between the various parameters involved in the scalability of the model with regards to the output power quality of the converter.Electrical Engineering, Mathematics and Computer ScienceSustainable Energy Technolog
