The power dispatch problem is first formulated for the HVDC grid with the aim of keeping the balance in real time and try to follow the 15-min schedules introduced by AC TSOs considering the ongoing changes in the HVDC grid. Next, the Auxiliary Problem Principle (APP) method is proposed to decompose the dispatch problem and distributed between connected AC operators who control the local converters. Two different approaches are tested and the sensitivity of the OPF updating rate has been evaluated for a 5-area HVDC grid with the wind production.enDistributed controlHVDC gridOptimal power flowWind farmTechnology::600: TechnologyConference Paper10.1049/cp.2015.0062Conference Paper
