We have been developing our capability in HVDC services, including complex modelling, project development and technoeconomic assessment. As well as comparisons of HVAC versus HVDC technologies and all of the associated studies and analysis required to make these assessments, we also have internal capability to carry out detailed modelling of IGBT -based voltage source converters. For further information, please see our most recent capability statement and please feel free to get in touch [email protected].
