摘　　要：传统方法不能对多阶段配电网进行有效协调,存在损耗较大、安全性低等问题。为了解决这一问题,提出基于演化算法的多阶段配电网智能协调方法。首先,确定有功可调设备以及无功的补偿设备,设定多阶段配电网智能协调目标函数;其次,从可靠性、节点功率、无功出力、线性锥潮流等方面对目标函数进行约束;最后,结合受约束的目标函数以及多阶段配电网的网络结构特点,采用演化算法对配电网开关状态进行最优组合,最终实现对多阶段配电网的智能协调。为了检验所提方法的有效性以及优越性,进行仿真对比实验。实验结果表明,所提方法在对多阶段配电网进行智能协调时弥补了传统方法损耗大、安全性能低不足的同时,所需时间仅为10. 43s、20. 15s,协调效率更高,具有一定的可行性。The traditional method can not coordinate the multi-stage distribution network effectively and has many problems,such as high loss and low security. In order to solve this problem,a multi-stage intelligent coordination method for distribution networks based on evolutionary algorithm is proposed. First of all,determine the active power adjustable equipment and reactive power compensation equipment,set the multi-stage distribution network intelligent coordination objective function;secondly,from the reliability,node power,reactive power,linear cone power flow and other aspects of the constraints on the objective function;finally,Combined with the constrained objective function and the network structure characteristics of multi-stage distribution network,an evolutionary algorithm is used to optimize the switching state of distribution network. Finally,the multi-stage distribution is realized. Intelligent coordination of the network. In order to verify the effectiveness and superiority of the proposed method,a comparative simulation experiment was carried out. The experimental results show that the proposed method can make up for the large loss and low safety performance of the traditional method in intelligent coordination of multi-stage distribution network,and at the same time,the time required is only 10. 43 s and 20. 15 s,and the coordination efficiency is higher and has certain feasibility.
