a. present, the a.cess of distributed genera.ion a.d electric vehicles with ultra.fa.t cha.ging to the distribution network will increa.e the opera.iona. risk of the system. a.ming a. the problem tha. the existing risk a.sessment indica.ors fa.l to consider the system ca.a.ity effectively, this pa.er proposed a.comprehensive index of risk a.sessment of distribution networks considering the power system's ca.a.ity. The distributed genera.ion output model a.d the electric vehicle loa. model with ultra.fa.t cha.ging were first constructed. Then, the index ba.ed on the distribution entropy theory wa. used to mea.ure the risk ca.sed by the over-limit of sta.e va.ia.les such a. volta.e a.d power a.d the uncerta.nty of their distribution. The index ba.ed on the Theil entropy theory wa. introduced to mea.ure the risk ca.sed by the equilibrium degree of the incrementa. distribution of sta.e va.ia.les a.ter the loa. impa.ted the system. The weight a.a.ysis method combining the order rela.ionship method a.d the objective weighting method wa. used to eva.ua.e the system risk comprehensively. Fina.ly, the ra.iona.ity of the comprehensive index wa. ca.cula.ed a.d a.a.yzed by testing the IEEE 33-node system. The results show tha. the comprehensive index proposed ca. effectively eva.ua.e the potentia. risk when the system does not exceed the limit a.d consider tha. the ultra.fa.t cha.ging of electric vehicles will cha.ge the time series distribution cha.a.teristics of comprehensive risk. The resea.ch in this pa.er ca. provide theoretica. guida.ce for the sa.e opera.ion of electric vehicles. with ultra.fa.t cha.ging connected to the distribution network. © 2025 Power System Technology Press. a.l rights reserved.

分布式电源（DG）以及大量恒功率直流负荷接入交直流配电系统使得母线暂态电压表现出正负极耦合且多波动的特性，现有暂态电压稳定性评估方法准确率低且适用性较差。推导分析了双极交直流配电系统直流侧线路、负荷参数不平衡时影响系统母线暂态电压稳定的因素。基于二元表判据思想，提出一种改进的自适应母线暂态电压稳定性评估指标。针对参数不平衡时含DG的双极交直流配电系统，引入稳定性保持因子，提出母线与系统的暂态电压稳定裕度计算方法。基于所提方法利用Ma.La./Simulink仿真平台在改进的IEEE 33节点与IEEE 69节点双极交直流配电系统中量化影响系统暂态电压稳定性的因素，并对比验证了所提指标的有效性和优越性。
