Unified Newton framework for the steady state simulation of networks with multiple AC-DC converters

As the numbers of converters and other power electronic devices of large rating increase, the search for the 'ultimate Jacobian' capable of representing the overall system behaviour continues. This paper describes the structure of a flexible Newton framework capable of incorporating the three-phase power flow and harmonic analysis in networks containing multiple AC-DC converters and, potentially, any other types of nonlinearities.
