The invention discloses a power distribution method and device for distributed charging piles. The method comprises the following steps: selecting a plurality of influence factors influencing power distribution of the distributed charging pile, determining a power distribution initial coefficient corresponding to each influence factor, calculating the weight and Gini coefficient of each influence factor by adopting an entropy method according to the power distribution initial coefficient, and calculating the power distribution of the distributed charging pile according to the weight and Gini coefficient of each influence factor. The method comprises the steps of calculating a comprehensive Gini coefficient of all influence factors, setting a constraint condition, taking the minimum comprehensive Gini coefficient as a target function, establishing a power distribution model, solving the power distribution model and obtaining a power distribution result of the distributed charging piles, and the fairness of power resource distribution of the distributed charging pile system can be judged through the Gini coefficient. Therefore, power resource allocation can be carried out on the distributed charging pile power system in the area more scientifically and intelligently, and ordered control and efficient management of the distributed charging piles are realized.

    本发明公开了一种用于分布式充电桩的电力分配方法及装置。本发明通过选取影响分布式充电桩的电力分配的多个影响因素,并确定各个影响因素对应的电力分配初始系数,根据电力分配初始系数,采用熵值法计算各个影响因素的权重和基尼系数,根据各个影响因素的权重和基尼系数,计算所有影响因素的综合基尼系数,设置约束条件,以综合基尼系数最小为目标函数,建立电力分配模型,求解电力分配模型,得到分布式充电桩的电力分配结果,由于可以通过基尼系数判定分布式充电桩系统的电力资源分配的公平性,从而能够更科学更智能的对区域内分布式充电桩电力系统进行电力资源调配,实现了分布式充电桩的有序控制和高效管理。
