One of the present barriers to the widespread use
of Modular Multilevel Converters (MMC) is the complexity of
its control. We use a suitable degree of simplifications of the
MMC converters, under given conditions, to allow system level
studies over potentially large networks. The analysis is based on
a recently proposed simplified model of the MMC. Based on this
model, we propose an analysis using the theory of Contraction
to define some stability conditions. Some simulation results allow
to see the advantages of the proposed method.
