National Grid has a good history of operating the AC network and also utilising a DC link as an interconnector. However NG has no experience in operating an integrated HVDC link in conjunction with the AC system.

The first intra network HVDC line is planned to be operational from 2013 to accommodate the significant increase in wind generation being installed in Scotland. It will be the responsibility of the system operator to determine the optimum power flow on this link by balancing the risks and flows between the parallel AC and DC networks.

Determination of how the system should be operated with the introduction of offshore HVDC lines to maximise the exploitation of renewable energy resources, especially wind and the types and amounts of reserve that are likely to be required.
