现有配电网评估方法未能涵盖智能配电网的核心价值和需求,且权重计算的主观性较强,易受人为因素影响,为此构建了一套新的智能配电网综合评估体系和方法。文中将指标体系划分为宏观需求指标集和微观评估指标集2个层次,其中,宏观需求指标集是智能配电网的宏观表象,微观评估指标集则表征其中的微观因素,两者间存在紧密的因果关联关系。同时提出了基于DEMATEL-ANP-反熵权法和改进灰色关联度法的组合权重分层优选模型,计算求解指标体系的指标权重值,使其兼顾主观性和客观性。通过在算例中的应用分析表明,该方法实用性较强,对于评估配电网的智能化发展水平和实际效益,分析识别电网的运行状态和薄弱环节有重要意义,可为智能配电网的建设改造和趋优运营提供参考。

The core value and demands of smart distribution grid cannot be covered by existing distribution network assessment method, besides the subjectivity of weight calculation is strong and easy to be impacted by human factor, so a new comprehensive assessment system and method for smart distribution grid is constructed. The index system is divided into two hierarchies: the macro demand index set and micro assessment index set, in which the macro demand index set reflects macro presentation of smart distribution grid and the micro assessment index set characterizes the micro factors in the former, and there is a close causal correlation relation between the two sets. Meanwhile, a combined weight hierarchical optimizing model based on DEMATEL-ANP-anti-entropy weight method and improved gray correlation method is proposed to solve and calculate index weights of the index system to make subjectivity and objectivity simultaneously considered. Applying the proposed method to a certain regional distribution grid, the results of application show that the proposed method is practicable and can assess the intelligent development level and obtain actual benefit as well as identify the operating conditions of distribution grid and its weak link. The proposed method is available for reference to the construction, planning, renovation and optimized operation of smart distribution grid.
