Abstract：Integration optimization is one of the key technologies for multi-terminal DC (MTDC) system. In this paper, an integrated parameter optimization configuration method for improving operational boundary is proposed for the three-terminal DC system. Firstly, the equivalent circuit and its characteristic model of MTDC system are established, and the influence of integrated parameters on system operational boundary is analyzed. Secondly, an integrated parameter multi-objective optimization model is proposed with the optimization goals of the smallest acreage difference between the stable area and the design area, and the lowest integration cost. Finally, the Pareto optimal solution set is solved by the NSGA-II algorithm, and the integrated parameter optimization configuration scheme is selected by the fuzzy clustering algorithm. The simulation analysis shows that the proposed method is effective and feasible, which can significantly improve the operational boundary of MTDC system while ensuring the system economics.
