摘要
通过将电动汽车充放电负荷特性与配电网已有的实际负荷特性相结合,利用最小二乘法拟合出新的负荷增长模型;然后将改进的模型嵌入供电能力计算方法中;最后在计及电动汽车的配电网架内以供电能力为指标利用支路交换算法寻找最优网架。通过31节点10 kV配电网进行分析,验证方法的有效性。
By combining the charge and discharge load characteristics of EV with the actual existing load characteristics of the distribution network,a new load growth model is fitted by least squares method.The improved model is then embedded in the power capability calculation method.Finally,taking the EV into account,taking the power supply capability of distribution network as an index,the branch exchange algorithm is used to find the optimal grid.The effectiveness of the method is verified by analysis on a 31-node 10 kV distribution network.
