多回直流之间协调规划的必要性提出了多馈入直流系统电网分区问题.本文提出一种多目标分区方法,用量化指标分析并建立了几种需要协调和互补的关系.根据图理论,将直流分区问题转换为图切问题,并利用谱聚类算法求解.最后,以实际多直流系统为例,验证了该方法的可行性和有效性.“,”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.
