摘　　要：传统的混合电动汽车充电模块有序充电分层控制方法存在网损率大,充电成本高以及充电稳定性差的问题,由此对混合电动汽车充电模块充电控制进行研究.从用户与电网角度构建有序充电分层控制目标,从充电时间约束、系统节点电压幅值约束、变压器容量的约束这三方面制定约束条件,选择动态规划逆序算法获得充电总功率的最佳约束条件;采用动态规划降维迭代方法,将分层控制问题转化为一维优化问题,完成混合电动汽车充电模块有序充电的分层控制.实验结果表明,此次设计的混合电动汽车充电模块有序充电分层控制方法比传统方法的网损率低,能够满足混合电动汽车充电模块有序充电分层控制需求,具有一定的应用意义.The traditional hierarchical control method for charging module of hybrid electric vehicle has the problems of large network loss rate,high charging cost and poor stability.From the point of view of users and power grid,the hierarchical control objective of orderly charging is constructed,the constraints are formulated in charging time,voltage amplitude of system nodes and transformer capacity,and the optimal constraints of total charging power are obtained by selecting the reverse order algorithm of dynamic planning.The hierarchical control problem is transformed into one-dimension optimization by using the method of dynamic planning dimension reduction and iteration,and the hybrid electric vehicle charging is completed.The experimental results show that the designed hierarchical control method for charging module of hybrid electric vehicle has a lower network loss rate than the traditional method,it can meet the demand of hierarchical control and have certain application significance.
