科学合理地规划城市电动汽车充电站是大规模电动汽车与智能电网友好互动的重要前提。基于模糊物元理论实现电动汽车充电站规划方案评估。分析了城市电动汽车充电站规划特征,构建了备选充电站评价指标体系。利用模糊物元分析法求解多个备选点的最优模糊物元序列,并将该序列作为参考序列。采用熵权法获得备选点对应评价指标的权重,通过灰色关联分析法计算备选点的加权灰色关联度,并依据关联度大小确定电动汽车充电站规划方案。最后,算例仿真结果验证了所提方法的合理性和可行性。
Scientifically and rationally planning a city electric car charging station is an important prerequisite for the friendly interaction between a large-scale electric car and a smart grid. EVALUATION OF PLAN SCHEME FOR EV CHARGING STATION BASED ON FUZZY MATTER ELEMENT. Analyzed the planning features of city electric vehicle charging station and built the evaluation index system of alternative charging station. The fuzzy matter element analysis is used to solve the optimal fuzzy element sequence of multiple candidate points, and the sequence is used as the reference sequence. The entropy weight method is adopted to obtain the weights of the evaluation points corresponding to the candidate points. The weighted gray relational degree of the candidate points is calculated by the gray relational analysis method, and the planning scheme of the charging station of the electric vehicle is determined according to the degree of relevance. Finally, the simulation results show that the proposed method is reasonable and feasible.
