B4-60 Designing HVDC Grids for Optimal Reliability and Availability Performance

The WG will develop the definitions of Reliability and Availability for HVDC Grids, e.g. considering the ability of different parts of the system to transport power between each part, as well as the capability of the converter stations to provide the relevant power interface between the HVDC Grid and the ac network.  Issues to be considered will include mean time to failure, repair times, capacity loss etc.  Reference will be made to the criteria developed for ac networks, as well as those developed for point to point HVDC systems.  All components of the HVDC Grid will be considered, but unavailabilities in the AC system should be disregarded in this context.

The WG will provide guidance in respect of the additional costs that may be incurred by adopting different reliability and availability criteria.
