摘要
随着电动汽车的快速发展,电动汽车充电机性能优劣极大影响了电动汽车用户的充电感受。文中提出了一种基于逼近理想解排序法(TOPSIS)的组合赋权评价方法,可以对电动汽车充电机运行性能进行全面评价。首先,建立充电机状态评价静态指标与动态指标,静态指标为充电机的输出性能、安全性能、电磁兼容性能与其他性能,动态指标为充电机对电网电能质量的影响指标;然后,采用博弈论把主观权重与客观权重整合优化为组合权重,并进行归一化处理;最后,基于TOPSIS法计算充电机的运行状态的贴近度,并得出最终评分。文中选取天津市场上3种常见充电机进行了全面评价,结果与其市场表现一致。因此,文中提出的充电机评价方法能够较全面地对充电机性能进行评价,可为电动汽车用户选购充电机提供参考。
With the development of electric vehicles (EVs), the performance of the chargers has a great influence on the feeling of EVs’ users. This paper proposes a method based on the combination weighting method and the TOPSIS (Technique for Order Preference by Similarity to an Ideal Solution) method in order to evaluate the operating performance of EV chargers scientifically and reasonably. Firstly, the static and dynamic indicators of the chargers’ performance evalua-tion are established. Static indicators include the output performance, safety performance, electromagnetic compati-bility and other performance of EV chargers. The dynamic indicators are defined as the influence of the chargers on the power quality of the grid. Then, the combined weights are formed with the subjective and objective weights based on Game theory and all the weights are normalized. Finally, the TOPSIS method is used to score the closeness of the operating state of the charger. Three chargers chosen from the Tianjin’s market are used in the case study and the evaluation results correspond with the sales. So the proposed method can evaluate the chargers in a comprehensive way and provide a reliable suggestion for the charger consumers.
