摘　　要：针对主动配电网(ADN)新特性及其自愈控制新要求,提出一种基于组合权重及属性区间法的ADN运行状态态势评估方法。在构建ADN运行状态态势评估指标体系的基础上,分别采用层次分析法(AHP)和变异系数法获取各评估指标的主观赋权和客观权重,并进一步基于最小二乘优化法实现组合权重赋值,然后提出基于属性区间理论的ADN运行状态态势评估方法。通过目标ADN中不同时刻的评估样本算例,分析验证了所提ADN运行状态态势评估方法的有效性、合理性和结果可观性。Aiming at the new characteristics of active distribution network(ADN)and its new requirements for self-healing control,a situation evaluation method of operating state in ADN based on combination weight and attribute interval method is proposed.With constructing of the index system for situation evaluation,the analytical hierarchy process(AHP)method and the coefficient of variation method are used to respectively obtain the subjective weight and objective weight of each evaluation index,and the combination weight assignment is further realized based on the least squares optimization method.Then,a situation evaluation method based on the attribute interval theory is proposed for the operating state in ADN.Finally,through the examples of different evaluation samples,the validity,rationality and observability of the proposed situation evaluation method are verified.
