This paper proposes different architectures for the coordinationof power injection in interconnected hybrid AC/DC gridswith Multi-TSO. The power dispatch problem is first formulatedfor the HVDC grid with the aim of keeping the balancein real time and try to follow the 15-min schedules introducedby AC TSOs considering the ongoing changes in the HVDCgrid. Next, the Auxiliary Problem Principle (APP) method isproposed to decompose the dispatch problem and distributedbetween connected AC operators who control the local converters.Two different approaches are tested and the sensitivityof the OPF updating rate has been evaluated for a 5-areaHVDC grid with the wind production.
