摘　　要：本文提出一种基于分层控制的有序充电控制架构,能够与传统电网控制架构融合的基础上,实现配电网范围内电动汽车和分布式可再生电源的协同有序控制。协同控制系统分为两层:配电网控制系统和站级控制系统。配电网控制系统以配电变压器处负荷方差最小为目标,以电动汽车总充电能量需求,充电功率为约束进行有序调度,并把调度计划上传给电网调度中心,以安排发电机出力;站级系统以实际充电曲线与调度指令误差最小为目标,以单台电动汽车和换电电池的充电电量需求为约束,进行实时有序充电控制。以北京市某地区实际数据为例,验证了协同控制系统的合理性和准确性。A hierarchical coordinated control architecture was proposed for synergetic control of electric vehicles（EVs） and distributed source in this work, it can easy integrate with the traditional control system of power system. The synergetic control system is divided into two layers： distribution network control system and substation control system. The distribution network control system taking minimizing load variance of the distribution transformer as objective function and EVs＇ total charging energy demand as constraints to realize the energy dispatch, and then send the whole power consumption schedule to the power system control center; substation system is to control EVs＇ real-time charging taking the minimizing the command error as objective and the single EV＇s charging and swapping energy constraints. Based on the actual data of a certain area of Beijing city as example, the rationality and accuracy of the synergetic control system was verified.
