Zusammenfassung:The close proximity and the necessity of coordination between multiple high-voltage direct currents (HVDCs) raise the issue of grid partitioning in multi-infeed HVDC systems. A multi-objective partition strategy is proposed in this paper. Several types of relationships to be coordinated and complemented are analyzed and formulated using quantitative indices. According to the graph theory, the HVDC partition is transformed into a graph-cut problem and solved via the spectral clustering algorithm. Finally, the proposed method is validated for a practical multi-HVDC grid, confirming its feasibility and effectiveness.
