This book provides a comprehensive review of the models and approaches that can be employed to
simulate modular multilevel converters (MMCs). Each solution is described in terms of operating
principle fields of applicability advantages and limitations. In addition this work
proposes a novel and efficient simulation approach for MMCs based on sub-circuit isomorphism.
This technique which has its roots in the electronics fields can be profitably exploited to
simulate MMCs regardless of the model used to describe its sub-modules including the most
accurate ones. Lastly this book considers a well-known high voltage direct current (HVDC)
benchmark system consisting of two MMCs. After describing the implementation details of each
benchmark component simulation results in several scenarios (ranging from normal operating
conditions to faults in the AC and DC grid) are included to validate the proposed approach and
showcase its key features. Due to its educational content this book constitutes a useful guide
for PhD students and researchers interested in the topic of MMCs and their simulation. It also
serves as a starting platform for junior electrical engineers who work in the field of power
electronic converters for HVDC systems.
