On-going changing of global power systems towards sustainability is the driving force behind the evolution of modular multilevel converters which provide high efficiency, reliability, superior power quality. The Modular Multilevel Converter topology is discussed intensively as a crucial part of DC grids, especially to integrate offshore wind power and solar power. Generally voltage source converter models are usually utilized for multi terminal investigations, A MMC based DC grid framework with a tripartite focus on internal converter. Besides an evaluation of the implemented MMC model that incorporates the available arm sum voltage, AC and DC system control concept suitable to handle unbalanced voltage conditions is derived for HVDC applications. Combined with wind farms and photo voltaic system MATLAB/SIMULINK Software and sim power systems tools are used. Mainly control system tools, power electronics and electrical elements tools are used.

Generalized modular multilevel converter modelling, designing, HVDC grid control, power converter, MMC with large number of sub modules, wind and solar power integration.
