Abstract：A normal operation mode of China's power grid is to transmit large-scale power from energy base to load center through UHVDC transmission. It was difficult to obtain the global optimal solution for the security constrained unit commitment problem due to the stage coordination mode between the HVDC plan and the generation plan at the sending and receiving terminals, and the HVDC transmission quota may be subject to the operation mode of the receiving power grid. The influence of power grid information such as the number of starting machines, start-up capacity and reserve capacity on the DC limit was incorporated into the unit commitment model, and an optimization model for the integrated day ahead dispatching plan considering the dynamic adjustment of DC limits was proposed. In order to meet the requirements of solving the model, a hybrid integer programming model solution algorithm with the coupling of decision variables was proposed. The proposed model was applied to the New England standard calculation example (10 units and 39 nodes) and a provincial power grid in China to verify the effectiveness of the proposed model.
