摘要

电动汽车充电站广泛接入到配电网中是实现电动汽车大规模推广应用的关键之一。为了评估与评价电动汽车充电站的接入对于配电网的影响,本文根据所提出的配电网承载能力评估指标体系,针对电动汽车充电站的充电方式与位置特点等分别建立电池更换站、居民区充电站、公共场所充电站的概率负荷模型。利用基于模糊理论、熵权法、层次分析法的综合评价方法对评估指标体系进行评分。在此基础上提出了一种优化配电网承载能力的重构方法。最后以IEEE 33节点配电网为算例对配电网承载能力评估指标体系与优化算法的可行性进行了分析和验证。

Abstract：

Widespread electrical vehicle (EV) charging station integrated to distribution network is one of the vital important factors for EV large-scale application. In order to evaluate the impact of the power distribution grid integrated with EV charging stations, according to proposed index appraisal system of distribution network supportability, for EV charging stations charging characteristics and location, the probabilistic load model of battery replacement stations, residential charging station and public charging station are established in this paper. The fuzzy theory, entropy weight method and the analytic hierarchy process are used to comprehensively evaluation the index appraisal system. Accordingly, this paper proposes an optimization reconfiguration approach for improving supportability of the distribution network. Finally the index appraisal system and feasibility of optimization algorithms are analyzed and verified by standard IEEE33 node distribution network.

Key words： Electric vehicle charging stations distribution networks supportability analytical hierarchy process ant colony algorithm
