Anotation

IEC TR 63179:2026, which is a Technical Report, provides technical information for planning high-voltage direct current (HVDC) systems with line-commutated converters (LCC), voltage sourced converters (VSC), or both. It provides general principles for deciding between HVDC and AC transmission systems, as well as processes and methods for preliminarily defining the HVDC transmission scheme, including selection of converter type and key parameters, grid stability analysis, and technical-economic comparison among various solutions. In addition, this document gives the objectives to be achieved in the planning phase. This document is applicable for planning a point-to-point or a back-to-back HVDC system. This document can also be used for DC grid systems (including multi-terminal HVDC systems) as a reference. This document is not exhaustive. It is possible that there are other specific aspects, that are particularly important for a specific HVDC project.
