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
