中文摘要：

近年来，随着现代电力系统朝着高度的相互关联性及复杂性方向发展，其脆弱性和巨大事故发生的危害性也日益彰显，所以，有效的电力应急管理显得尤为重要。全面评估电网企业的大面积停电应急能力，明确应急工作的目标和方向成为研究的重点。在运用层次分析法建立的评价指标体系的基础上，通过引入云理论及相关方法，可以获得一种新的电力应急群体决策评价方法。该方法利用云模型完成了评价过程中定性与定量之间的转化并同时考虑了模糊性和随机性问题。最后通过实际算例分析并验证了该方法的有效性和合理性。

英文摘要：

In recent years, modern power system is moving in the direction of high interconnectivity and complexity, which is inherently accompanied by a high degree of vulnerability and hazards of huge accident. Therefore, an efficient power emergency management is particularly important. The assessment method for power emergency is aimed to fully and effectively evaluate the emergency ~sponse capacity of power grid enterprises after a blackout and determine the objectives and direction of power emergency work. On the basis of the power emergency evaluation system established by Analytical Hierarchy Process （AHP）, a new method and theory of power emergency group decision-making bard on cloud model is introduced. The cloud model is firstly employed to solve the power emergency problems. The transformation between qualitative and quantitative in the evaluation process is realized with the fuzziness by considering the subjectivity of group decision-making. Finally, a numerical example is served to demonstrate the reasonableness and effectiveness of the developed method.
