摘　　要：文章详细探讨了特高压直流输电系统的评价与优化方法,强调了在能源需求增长和结构转型背景下该系统的重要性。一方面,建立一套全面的评价指标体系,涵盖网损、静态安全、短路比等关键方面,并按照系统性、可量化性等原则精心选取和设计。另一方面,介绍基于主客观最优组合赋权的优选方法,该方法结合了G1法和熵权法,旨在提供一个科学且全面的评价框架,以支持更精准的系统评价和决策制定。通过构建评价矩阵和执行相对贴近度优选,不仅优化了多馈入直流系统的评价过程,还提升了决策的科学性和准确性。This paper discusses the evaluation and optimization of ultra high voltage direct current system,and emphasizes the importance of this system in the context of energy demand growth and structural transformation.On the one hand,a comprehensive evaluation index system is established,which covers the key aspects such as network loss,static safety,short circuit ratio,etc.On the other hand,the paper introduces the optimal selection method based on subjective and objective optimal combination weighting,which combines the G1 method and entropy weight method.By constructing the evaluation matrix and optimizing the relative closeness,this paper not only optimizes the evaluation process of multi-feed direct current system,but also improves the scientific and accurate decision.
